Three main mobile operators of Thailand ("big three") - AIS, DTAC and True Move. There is a number of smaller providers or MVNOs that lease government bandwidth mostly on the CAT network (such as Finn, Penguin or My).
Purchase of a new SIM card is easy, and can be done at operators' shops in major malls or at the airports or at any 7-Eleven, Family Mart and many mini markets. Thailand does, however, have a strictly enforced mandatory SIM card registration and you will need to provide your ID or passport at the point of purchase (see below).
Generally you have the choice between two options:
- buying your tourist SIM at an airport store or flagship store of the operator in a shopping mall
- buying your local SIM in an operator store or mini market like Family Mart, 7-Eleven and others
Arriving at BKK (Suvarnabhumi) airport in Bangkok, the 3 major players have their flagship stores in the big arrivals hall just past the customs check almost side by side. There you can compare prices and promotions. At DMK (Don Mueang) Bangkok's budget airport you can now find the stores of the three major providers located next to each other facing exit gate 6. At Phuket's internatl. terminal and Chiang Mai's airports you find stalls of the providers too. Alternatively, you can go to a flagship store of the provider found in major shopping malls. If you don’t want a tourist SIM, there are several 3rd party phone shops even at BKK airport near the train entry point at the lower level, as well as most operator stores and mini-markets like 7-Eleven and FamilyMart in town.
Tourist and local SIM cards
Some users argue that local SIM cards bought in a mini store are cheaper. That's right, but tourist plans sold only in branded operator stores at the airport or in malls have other advantages. If you want to call IDD, they give you the lowest rates (ask for the prefix). In these stores you will get English-speaking service and they will install the SIM in your device with all the configurations. You clearly understand your plan and the included services print out in English. They are not a rip-off like in some other SE Asian countries and a valid option for not so experienced users. In addition, for late-night arrivals generally the operator desks at the airport selling tourist SIMs are the only ones active (the registration system mini-markets use for registering local SIMs shuts down at night so even if the store is open, they can not complete activation for you), so if you want a local rate plan you will have to wait until the next day.
On the other hand local SIM cards are somewhat cheaper for data, have speed-limited but true unlimited usage options available, and they support international roaming if you plan on going to other countries in the region later. In addition, the big providers are now willing to provide support in English for visitors using these local SIMs if you go to one of the flagship locations or call the customer service line. You will, however, need to know what plan you want and which strings are attached. The cheapest plans are severely throttled in max. speed, some as low as 384 kbps. But they can be a very good value for regular visitors to the country as well as travelers around the region who don’t want to have to find a new SIM (and register ID again) for each country they visit.
In the list below we show some of the local prices as an indicative because there are many more options and promotions around. These plans are separate from the Tourist and Roaming SIM cards that you need to buy in a branded store and both lines can't be mixed.
Concerns for all providers
The big three operators have SIM cards for all sizes - normal, micro and nano SIMs. All major operators allow tethering and they treat all data going through their network equally. If you are using an iPhone, you may need to perform a network reset or a carrier update for the mobile tethering option to appear. Tethering provides, most of the time, excellent quality. It's sufficient for VoIP and supports PPTP/SSL/IPsec VPNs. If you work remote and are a heavy user, you will have a trouble free experience.
For voice calling overseas heavily reduced rates even below VoIP providers are offered by the three major operators using special IDD prefix codes on Tourist Plans only. Let them give you the cheapest option for your destination which has to be dialed before the country code (see below).
Adding credit or airtime is quite easy as long as you stay in Thailand. Loading airtime gives you ability to make calls or subscribe to data packages and also extends the lifetime of the SIM card. A few physical places where you can top-up are 7-Eleven, Family Mart, BigC, Tesco, phone kiosks and the outlets of the operators. Note that 7-Eleven can only sell top ups for cash and not for AIS.
Adding credit online is also possible and there are some options:
- Officially, dtac no longer accepts foreign credit cards for top-ups via its app for no fee. Foreign Visa and MasterCard cards have been tested and no longer work as of 2021. However, foreign JCB cards still work.
- MobileTopup.com accepts Alipay, Cryptocurrency international and local Visa and MasterCard with a fee, and PromptPay without.
- If you have Bitcoin you can top-up at MobileTopup.com or bitrefill.com
- If you use Webmoney you can do it through wm-thailand.com. Most of these options add face value surcharges, and conversion fees may be added in the process. They remain mostly limited to the 3 major providers.
- For developers, there is also a API service.
- Rabbit LINE Pay, a local digital wallet built into the LINE messaging app, supports foreign Visa/MasterCard/JCB cards and allows top-ups to AIS or dtac accounts for no additional fee. You will need to set this up after arrival, however, as it requires a Thai mobile number as well as the address of where you are staying in Thailand.
There are a lot more resellers found on the internet, all using the same API and provider. If one of them does not work with your number and payment option, trying another one will most likely give you the same error.
You have to top-up a Thai SIM card every 45 days or pay more to add validity in order to keep it alive as well as make at least one call or outgoing SMS activity every 6 months. Many Thai SIM cards expire in 45 days after the last top-up, unless you are able to add extra validity. The bare minimum to maintain validity is 10 THB every month. DTAC's policy is that every top-up extends SIM validity by 30 days, so multiple small top-ups will keep your SIM active for longer than one large top-up (example: 5 x 20 THB top-up extends your SIM validity by 150 days compared to a single 100 THB top-up). Additionally, True and DTAC allow you to extend validity for a price, check this site on how to extend.
Before you purchase any SIM card, make sure that the network you are choosing is compatible with your devices (see below). The big three providers have different networks operating on more than one set of frequencies that are combined through domestic roaming. So you should better enable roaming on your device, even for domestic use. Most old networks mainly on 2G are about to decommissioned soon. These frequencies are used for 3G, 4G/LTE and since 2020 5G NR:
- AIS has 3G/DC-HSPA on 900 and 2100 MHz (and roaming on TOT 2100 MHz) and started in 2016 with 4G/LTE Advanced called "4.5G" on 700, 900, 1800, and 2100 MHz (bands 1, 3, 8, and 28). 5G started on 2600 MHz (n41) and mmWave (n258).
- dtac has the largest 3G spectrum: 3G/DC-HSPA on 850 and 2100 MHz and 4G/LTE on 700, 1800, and 2100 MHz (bands 1, 3, and 28), with 5G on 700MHz (n28) and mmWave (n258).
- TrueMove H has 3G/DC-HSPA on 850 and 2100 MHz 3G/DC-HSPA and the largest 4G/LTE spectrum on 850, 900, 1800 and 2100 MHz (bands 1, 3, 5, 8, and 28) as well as TDD-LTE 2300 MHz (band 40). 5G started on 2600 MHz (n41) and mmWave (n258).
- CAT: is on 3G/HSPA only on 850 MHz (with national 4G roaming for its My brand on True's 4G/LTE network on 1800 and 2100 MHz).
- TOT: is on 3G/HSPA on 2100 MHz in Bangkok only (nationwide through 3G roaming on AIS) and plans 4G/LTE on 1800 MHz 4G/LTE (B1) and 2300 MHz TDD-LTE (B40) as well as mmWave 5G (n258).
Note that all old 2G/GSM networks are to be shut down within the next few years as the providers need more spectrum for LTE. AIS has sealed a roaming agreement with dtac for 2G on their 1800 MHz band, which dtac is going to use until 2018. True has leased back bandwidth from CAT on 1800 MHz for 2G until the end of 2016 while TOT has never had any 2G. However, all providers and the NBTC have agreed in late 2019 to indefinitely postpone the shutdown date, so the networks remain in place for now, but be aware that the shutdown plans can resume at any time.
Coverage, speed and 5G
The leading trio is very much on par. 4G/LTE availability is generally high at about 90-95% of the population on all three major networks. According to Open Signal in 2020 AIS had the best 4G coverage at 95%, while dtac had the best download speeds at an average 10 Mbps. Sometimes there is congestion in city areas. 5G started on AIS and True in 2020 on 2600 MHz (n41), while dtac is planning to deploy 5G on the 700 MHz band. In addition, all providers have mmWave (n258) spectrum and are deploying it.
IDD Calling Prefixes
Thailand is one of the few countries where some international calls are charged lower than domestic or even VoIP calls. For this you have to use certain IDD prefixes. So the correct order to dial abroad is:
<IDD prefix> <country code> <area code> <local number>
The prefixes differ between operators and are added at the end of each section. The major providers give out special discounted prefixes on which major landlines in Europe, America, Asia and Australia can be called for as low as 1 THB per min. On all operators you can use CAT's prefix 009 (price list) or TOT's 008.
New biometric registration (effective 2017)
Under the law all SIM cards have to be registered from 2015. You will need to show an ID at the point of purchase. This is now enforced in all providers stores and outlets very strictly and from the end of 2017 a new biometric system is introduced. You will now additionally have your face scanned or fingerprints taken.
The new system is mandatory from 2017 to the registration of both new prepaid and postpaid SIM cards, but not to existing SIM card holders. It's to be used across Thailand in all 55,000 customer service shops and outlets. Operators can choose to use either the face or fingerprint recognition verification system.
The number of new SIM cards sold by all three major mobile phone operators that are ordered to introduce this new biometric registration system is around 4.2 million units monthly. Under the previous method, the registration locations copied only the ID cards of the SIM card buyer together with a barcode of the purchased SIM card.
Under this new method, new SIM card subscribers will have to insert their ID cards into the fingerprint reader or the face recognition card reader at the registration locations. The card readers are connected to the mobile phones or PC of the registration locations. In the case of the face recognition system, the locations will take the SIM card users’ face with the mobile phones embedded with an NBTC registration application. Then the app will see, if the captured face matches with the face stored in the ID card database. Foreigners buying SIM cards in Thailand will have their faces scanned and matched against their passport photographs.
In 2018 new restrictions on the number of SIM cards have been implemented. Users can from now on only buy up to 5 SIM cards from one mobile provider, which then must be registered via the country’s biometric verification system (a face recognition or a fingerprint verification).
Thailand has a very strong network of public WiFi hotspots all over the country. Some of them e.g. in airports are free and publicly available. Others in hotels and restaurants are for customers only. There are many hotspots of AIS, True and dtac throughout the country. If you purchase a SIM, also check for the accompanying WiFi plan. In general monthly plans over 500 THB per month will include free WiFi package. WiFi plans can be purchased separately as well, and paid from your phone balance. While True has the largest WiFi presence, AIS has the largest roll out of the latest 802.11n WiFi points, and generally has better speeds and reliability.
Some prices below are without taxes. Expect to add 7% tax for the final price.
AIS (1-2-Call, you! Mobile)
AIS has the largest 2G/3G network with a 50% customer share. It's part of the SingTel Corp. that also owns e.g. Optus in Australia and SingTel in Singapore.
Surprisingly, AIS was the last major provider to start 4G/LTE in 2016 on the 1800 and 2100 MHz band (B3, B1), partly marketed as "4.5G" or LTE Advanced. It now covers 80% of the population in 2017: 3G/4G coverage map and is competitive to True and dtac. 5G has started on 2600 MHz (n41). AIS' prepaid brand is often dubbed 1-2-Call.
You can get their SIM cards online (only for old 3G SIMs) to be sent to a Thai address and at airports, major shopping malls, telecom stands, in AIS and Telewiz branded stores (shop locator in Thai with map). Change language of their messages to English by pressing *700# <call> and choose option 5.
Top-up, balance check and validity
Top-ups can be done in many ways, but ATMs and internet banking require Thai bank accounts. So topping up by an electronic top-up or cash card is recommended. They are sold at some convenience stores such as Family Mart, Tesco/Lotus, Big C or online. 7/11 stores do not sell AIS top-ups anymore, but usually you can find a stand alone vending machine which will allow you to use cash to top up. A small fee will be deducted.
Every AIS store has a "payment kiosk" that is an automated top-up machine as well. These green/white machines are also found at malls and MRT/BTS stations, and are the fastest option to Top-up. There is no markup, 500 THB in gives you 500 THB credit.
Top-ups can also be made by credit card on the AIS service page in increments of 50 THB. International credit cards are a mixed bag, most of them do not work.
Top-ups up to THB 150 are valid for 30 days and of more than THB 150 are valid for 60 days. In case there is no usage or no recharge for 90 days, with no remaining validity, the number will be automatically terminated.
To maximize validity extension, top up in small increments e.g. For THB 500 credit, top up THB 100 5 times and the validity will be extended 5 times instead of once with a single THB 500 top-up.
To top-up by code, type *120*<16 digit voucher PIN>#. To check account balance and validity, type *121#. Check data balances by *121*3#.
1-2-Call SIM cards are their regular prepaid voice and data cards. All new SIM cards include 4G/LTE and 5G are sold for around THB 50 with a THB 15 call credit and some bonuses. They offer a huge array of SIM cards:
- The One SIM: This SIM was introduced in 2018 as often a specific SIM can't be found. When you top-up at least THB 150 cumulatively a month you get 2 GB of YouTube data for 30 days as well as unlimited data on AIS Super WiFi hotspots, and every day you top up at least THB 50 you get unlimited YouTube data for that day. In addition, you get unlimited data for use of TikTok. However, all free usage must be redeemed through the MyAIS app (not geo-restricted).
- Super Social: This SIM is geared to social media. For a top-up of at least THB 150 you get unlimited use of Facebook, Facebook Messenger, Line, Twitter, and WhatsApp at 4 Mbps for 30 days and unlimited AIS Super WiFi data for 30 days.
- Super Net SIM: This is their best SIM for data-use. It's sold for THB 50 (discounted to THB 25 if purchased together with a top-up of at least THB 150). After activation you get unlimited internet at 2 Mbps valid for 30 days, and upon topping up at least THB 150, for the following 30 days as well. Regular packages (see below) can also be added. It is available at FamilyMart stores.
- Zeed: This SIM is targeted to teens and has been one of their best plans, but seems to be faded out. On activation, it includes 500 MB of data, and 2 GB of YouTube data for 1 month. It also includes AIS Super WiFi. These data allowances renew for future months if you top up at least THB 100 per month. However, this SIM is very difficult to find, and may be sold by shops at a mark-up over face value (e.g. 99 THB rather than 50 THB).
- Net Marathon: These are preset SIM cards valid for 6 or 12 months:
- 7.5 GB per month at 1 Mbps for 6 months: THB 600
- 7.5 GB per month at 1 Mbps for 12 months: THB 1200
- 20 GB per month at 4 Mbps for 6 months: THB 1400
- 100 GB per month at 10 Mbps for 12 months: THB 1790
- Zodiac SIM: This SIM comes in 12 different zodiacs. It's sold for THB 99 and contains 500 MB data and WiFi for 7 days and another 1 GB data as bonus if you top-up at least THB 150.
- Others: AIS has some other SIM cards, but most are probably not of interest to visitors like Sood Koom SIM. Their tourist SIM called Lucky SIM and their roaming SIM called SIM2Fly are featured further below in the article.
High speed data packages
AIS has a rather large and confusing range of data add-on packages (in addition to their many SIM card types, some of which already come with data). These data packages on up to 4G/LTE can be activated on all their SIM cards from above.
|Data||1 day||3 days||7 days||30 days|
|100 MB||9 THB|

If any internet usage allowance has not been used after the package validity ends, the remaining internet allowance will be forfeited. Excess usage will be calculated at the rate of your main package. Service rates are 7% VAT exclusive.
Low speed data packages
Furthermore, some throttled packages are sold with "unlimited data" in different speeds. However, since 2019 these are no longer real unlimited packages as after some threshold they are capped to 128 or 64 kbps/s.
|64 kbps||unlimited||30 days||29 THB|
|512 kbps||500 MB||24 hours||22 THB|
|2.5 GB||7 days||89 THB|
|7.5 GB||30 days||300 THB|
|1 Mbps||500 MB||24 hours||25 THB|
|2.5 GB||7 days||120 THB|
|7.5 GB||30 days||350 THB|
|4 Mbps||1 GB||24 hours||32 THB|
|7 GB||7 days||220 THB|
|20 GB||30 days||650 THB|
|6 Mbps||1.5 GB||24 hours||45 THB|

|10 Mbps||2 GB||24 hours||55 THB|
|14 GB||7 days||330 THB|
|33 GB||30 days||1100 THB|
For activation use their app or go to this site, pick your pack, enter your number and receive the SMS activation code.
As of early 2020 AIS has a special promotion with unlimited volumes only for new SIM cards. It must be activated within 7 days of card activation and works only if no other package has been applied to the card before:
- max 4 Mbps: 150 THB, activation: *777*967*306650#
- max. 10 Mbps: 200 THB, activation: *777*968*306650#
It auto-renews for up to 12 months, if account balance allows it.
Social media packages
Social media users can add these packs with unlimited use of Facebook, Line, Instagram and WhatsApp:
- for 24 hours: incl. 300 MB general data @ 384 kbps: 17 THB, activation: *777*766#
- for 7 days: incl. 100 MB general data: 59 THZB, activation: *777*7013#
Tourist SIM: AIS Lucky SIM
Alternatively, AIS offers their Lucky SIM to visitors in five different starter packs (prices inclusive of VAT):
- for 49 THB: 7 days of free WeChat and AIS Super WiFi
- for 88 THB: 7 days of unlimited mobile data at 1 Mbps and AIS Super WiFi, extendable for 88 THB per 7 days, automatically charged if there is enough balance in the account
- for 160 THB: 5 GB data, 15 THB call credit, free social apps and AIS Super WiFi for 5 days at AIS shops and retailers.
- for 299 THB: 15 GB data, 15 THB call credit, free social apps and AIS Super WiFi for 8 days (16 days in promotion) at major airport stores, other AIS stores and Family Mart nationwide.
- for 599 THB: 30 GB data, 15 THB call credit, free social apps and AIS Super WiFi for 15 days (30 days in promotion) at AIS stores nationwide.
All data beyond the quota is throttled to 384 kbps (and all data packages added to the 49 THB starter SIM will be throttled to 384 kbps). Social apps include Facebook, Line, WeChat, Twitter, WhatsApp, TikTok, and Instagram. On all Lucky SIMs the cheap IDD prefix 00300 enables calls to some destinations like Germany or China at 1 THB per min. For more countries use 003 prefix for reduced call rates.
The default data rate outside packages is 2 THB per MB. These add-ons are advertised for the Lucky SIM (tax incl.), valid for 8 days, but in fact you can add any regular package shown above too:
|39 THB||3 GB||*777*7102#|
|59 THB||5 GB||*777*7104#|
|90 THB||10 GB||*777*7106#|
|150 THB||20 GB||*777*7442#|
When used up, max. speed will be throttled from to 384 kbps.
AIS WiFi passes
AIS has many WiFi hotspots, especially in shopping malls and airports. AIS Super WiFi Packs are available with unlimited data volumes:
|9 THB||1 hour||*777*380#|
|19 THB||5 hours||*777*381#|
|29 THB||1 day||*777*382#|
|99 THB||30 days||*777*384#|
You will need to purchase any AIS SIM card (for 50 THB) in order to buy a WiFi pass. All packages now provide access to to AIS Super WiFi, which has superior speeds (tested up to 150/150 Mbps in real world use) compared to the normal WiFi (capped at 10/1 Mbps). For the 1 hour and 5 hour packages, time is counted from login to logout. To log out, go to wifi.ais.co.th.
Some SIMs and packages come with WiFi; to obtain the password dial *388*1# or get it online.
Roaming SIM: SIM2Fly
The AIS SIM2Fly was originally meant for outbound Thai tourists, but is now being distributed throughout the region, because it offers quite good roaming rates. The SIM2Fly SIM card comes in 2 varieties:
- 399 THB: SIM card for certain countries in Asia and Australia for 10 days
- 899 THB: SIM card for certain countries in Europe and the Americas for 15 days
The Asian version comes with 6 GB roaming data at 3G and 4G/LTE speeds and is valid for 10 days in China (incl. Tibet), Japan, South Korea, Singapore, Malaysia, Hong Kong, Laos, India (in certain states only), Taiwan, Macao, Philippines, Cambodia, Myanmar, Australia, Nepal, Indonesia, Qatar and Sri Lanka and now in Vietnam and Brunei too.
After the main package has expired, you can add a new data package. For more data in the same countries you can use following codes to extend your data package:
- 1 GB valid for 2 days: 119 THB, activation by *111*356#
- 4 GB valid for 8 days: 299 THB, activation by *111*354#
As the data package is 100 THB less then the price of a new SIM card, it may be worthwhile to keep your SIM active. You can extent the validity by various methods listed here. AIS SIM2Fly can be found for sale all over SE Asia. Some online shops are selling SIM2fly SIM cards to foreign countries for a surcharge and delivery fees. To top-up from abroad you can use https://mobiletopup.com/ (5% fees apply for credit card payments and amounts start at 20 THB) or other agencies that can charge up to 30% fees.
Be aware of the strict Thai SIM cards validity rules: prepaid SIMs can expire in as little as 45 days after last use. Any top-up (regardless of the value) extends validity for another 30 days. To maintain a validity of one year then, you can top-up 12 times, getting 30 days with each top-up. Minimum top-up value is 10 THB, but most international agencies start at 20 THB only. As long as the SIM is active, your credit balance remains for next use. There is one online service that will automate this process to add 360 days to your prepaid SIM for a fee. Generally, these top-up requirements can make the deal much less attractive for occasional users, but remain a good option, if you buy and load it in Thailand for an onward journey through SE Asia.
As of 2019 the AIS SIM2Fly is now available as an eSIM, and initially supported by the iPhone Xr and Xs. The eSim has the same data plans of the conventional SIM, but no physical SIM is needed. The eSIM should work on any device with an embedded SIM that can scan a QR code to load the SIM profile. For now eSIMs can be purchased at AIS shops, on the AIS website, and various online resellers. Keep in mind eSIMs need to be reissued if you wish to switch phones or deactivate the plan.
You can switch the SMS language of the plan to English with code: *119*2#
- IDD prefixes for calling abroad: 003 (quality) or 00300 (budget on some plans like Traveller SIM, from THB 1 per min)
- APN: internet
- Websites (in English & Thai, click the flag icon on the top right to change language between English and Thai): https://www.ais.co.th/en/index.html?intcid=getpage-en-header_menu-logo#0
dtac for Total Access Communication is Thailand's 3rd largest network by the number of users. It's partly owned by Telenor group from Norway and is the network that owns the biggest wireless bandwidth in the country. Its prepaid brand is called Happy.
4G/LTE started in 2014 on 2100 MHz (B1) in Bangkok only and has been expanded in 2015 to Phuket and Pattaya and another 40 cities nationwide: 4G coverage map. In 2015 4G/LTE was started in the metro Bangkok area mostly on the additional 1800 MHz (B3) frequency which is much more common internationally. In June, 2018 DTAC started offering 4G+ on the rare 2300 MHz frequency through a deal with TOT. 5G is planned on 700 MHz.
You can get their SIM cards from almost any shop including at the airports, but if you prefer, you can obtain it directly from their stores. The current list of available SIM starters is here.
- Happy NET SIM: Costs 49 THB, comes with unlimited Facebook, Facebook Messenger, LINE, Instagram, Twitter, and YouTube at 42 Mbps for 7 days after every top-up of at least 50 THB, up to 4x per month and 12 months from activation.
- Happy Combo SIM: Costs 99 THB, only available at 7-Eleven, comes with unlimited data at 2 Mbps and unlimited number of 15-minute calls to other DTAC numbers for 7 days from activation
- Go Plearn SIM: Costs 49 THB, comes with free basic 4G internet at slow 64 kbps for 12 months from activation (from other SIMs change by *103*55*9# for 30 THB), which can be extended another 12 months with at least 10 THB of paid usage in the past 12-month period.
- Super 4G SIM: Costs 49 THB, comes with free YouTube streaming at night (midnight-8am), zero-rated music streaming through the Music Infinite app and 1GB per month for 7 days up to 12 months when top-up at least 150 THB per month (press *103*333*9#).
- Gift SIM: A free limited-time promotional SIM available until the end of 2021. 500 MB for 3 days is given out with a 20 THB top-up within 3 days of activation, and 1 GB of data for 7 days is given out each month with at least 100 THB top-up.
- Net Zing X2 SIM: Costs 25 THB, gives out unlimited data at 2 Mbps for 15 days with any top-up within 15 days of activation. After this period, two additional unlimited-usage packages at 2 Mbps are available for this SIM- 100 THB for 7 days (activate by dialing *104*101#) and 300 THB for 30 days (activate by dialing *104*103#). Both packages auto-renew for up to 12 months from activation date if there is sufficient balance on the renewal date.
There are other SIM starters available, but they are either only available online or are not as good value as what is presented here.
High speed data packages
Default rate for data is 1.99 THB per MB except for the Happy NET SIM where it is 0.99 THB per MB. dtac offers two main categories of packages: those with a certain high-speed volume that is throttled when used up and those that are reduced in speed from the start and are called 3G or light packages.
For the first category, you get connection at full 4G/LTE or 5G speed up to 100 Mbps for a certain amount of data, then your speed will be capped at the stated fair use policy (FUP) maximum speed which is varied respective to the plan you choose (but you can use them as much as you like, they are unlimited after all).
Some options only appear online. They can be activated either on the dtac app or by finding the package on this page, clicking "more detail" on the desired package, and following the steps.

Unofficially, their regular 3G and 4G packs have sometimes worked in the past, so you might give them a try. However, effective 2018, this seems to be discontinued and all attempts to activate a regular bundle on a Tourist SIM seems to usually be denied.
True has like dtac and AIS many WiFi hotspots throughout the country. They have the biggest WIFI network with more than 100,000 hotspots: Hotspot Locator. When not included in your plan, they offer these packages for a max. speed of 200 Mbps (add 7% taxes):

For roaming there are two options- one is to purchase a standard prepaid starter pack, which supports roaming.

The APN may need to be set manually to 'internet' and username/password 'true'. Both standard prepaid starter packs and the Travel SIMs can be reloaded with the following packages:

My (by CAT)
My is a MVNO operated by CAT Telecom Public Company Ltd., the state-owned company that runs Thailand’s international telecommunications infrastructure, including its international gateways, satellite, and submarine cable network connections.
It's the 4th largest mobile network operator in Thailand and owns spectrum on the 850 Mhz frequency, rents it out to True Move. In return it can use 20% of the bandwidth for their own My by CAT operation and other MVNOs (see below). Towers and network are operated by True Move for their own 3G 850 Mhz. In 2016 they started national roaming with True for 4G/LTE. To all prices below add 7% taxes.
Frequencies and coverage
My has only 3G/HSPA+ on 850 Mhz (= B5) without fall-back to 2G. As My uses the same 850 MHz network as True Move, their 3G coverage is the same. By 2014 it had a coverage of approximately 97% of population and consisted of around 14,000 BTS. But as there are way less users on CAT's 20% share as they have roughly a market share including MVNOs of 1-2% so far.
Starting in 2016 they opened up 4G/LTE access by national roaming on the 4G/LTE 1800 MHz and 2100 MHz network of True Move. Summing up, for the CAT offers below you need 3G on 850 MHz and 4G/LTE on 1800 and 2100 MHz (B3, B1).
My by CAT shops and CAT service centers are now showing up in some shopping malls (locator in Thai-English).
Top-up vouchers can be found at various locations like CAT stores, AJ Sabaidee top-up kiosks, U Top-up at Big C and postal offices, Tesco Lotus and 7-Eleven (only for THB 100 and 300). To top-up by code type *901*<voucher code>#. To check balance type *902#.

Penguin SIM (on CAT)
In 2016 some new MVNOs started mainly on the CAT network. The most visible so far is Penguin SIM by White Space. It's aimed at the Thai youth, but accessible to everyone and heavily marketed at small street vendors and other places. It has certain pros and cons, you should be aware of. Most starter kits are on the 3G-only CAT network (see above). While it has a good coverage identical to True's 3G footprint, it doesn't offer a 2G fallback and you need to have a device capable of 850 MHz in 3G. They sell only one starter kit that supports 4G/LTE, it only offers access to True's 2100 MHz (B1) network, and it is named very similarly to another, 3G-only starter kit (SIM Rider Plus compared to SIM Rider) and can not be changed later so make sure you're purchasing the correct SIM starter kit at the store.
Penguin SIM has very low prices, but most of their rates are severely throttled. That means that they can be good for messaging like LINE (preferred messenger in Thailand) or basic internet, but inconvenient for browsing websites. All of their publications are in Thai only. To all the given prices below (except on the Tourist SIM) add 7% taxes.
All their SIM cards are sold for THB 49 with THB 20 credit when you top-up THB 50-100 only at street vendors and major kiosks chains. They are rarely offered at airports or tourist hotspots etc. On the street you will be told that you don't need registration. As it's required by law, you'll risk disconnection, but you might be fine for a short time. In a kiosk chain store let them register it for you.
Top-ups are available at the usual stores like FamilyMart and 7-Eleven. Check balance by *502#, check your number by *504#.
They offer different plans that can't be changed except from a classic or SIM Rider SIM to a Sud Soi SIM. As it's only written in Thai on the package, it might be hard to find out as they differ:
- Classic Pinguin SIM is sold in some Family Mart stores for THB 49 with THB 15 credit valid for 30 days. Internet is included at THB 39 per day, but severely throttled at 128 kbps.
- SIM Rider is sold in some 7-Eleven and Jiffy stores. It has unlimited data capped at 1 or 4 Mbps.
- @ max. 1 Mbps: THB 20 for 24 hours - *555*81#; THB 55 for 3 days - *555*82*1#; THB 99 for 7 days - *555*83*1#; THB 279 for 30 days - *555*87*1#
- @ max. 4 Mbps: THB 24 for 24 hours - *555*84#; THB 63 for 3 days - *555*85*1#; THB 119 for 7 days - *555*86*1#; THB 450 for 30 days - *555*88*1#
- SIM Rider Plus is Penguin's only 4G/LTE SIM. It charges a default rate of 0.50 THB per MB and has the following packages of full-speed data with overuse at 128kbps:
- 1 GB: 50 THB for 24 hours- *555*92#, 85 THB for 7 days- *555*93#
- 3 GB: 195 THB for 31 days- *555*94#

- Me and You SIM is Penguin's newest starter pack and available in some 7-Eleven stores for THB 49 with THB 15 credit valid for 30 days. Internet is included at THB 20 per day, but severely throttled at 128 kbps.
- Sud Soi SIM has Penguin's most comprehensive selection of add-ons, with unlimited capped-speed data add-ons ranging from 24 hours to 1 year as well as some data add-ons with FUP. The default rate without an add-on is 0.90 THB per MB.

Finn Mobile (previously LINE Mobile, on dtac)
LINE is the most popular social messenger in Thailand. In 2017 they teamed up with dtac and launched LINE Mobile powered by DTN on dtac's 3G and 4G network as a MVNO. They offer unlimited use of free Line services including Line Messenger, Line Calls, Line Video, and Line TV not debited from your data allowance. In 2019 Line Mobile was rebranded to Finn Mobile.
This SIM card is only available online through their website delivered by courier all over Thailand selecting one of their plans from below. For activation foreigners need to send a selfie with the SIM card and another pic with the photo of your passport. So it might not be so useful for travellers as it might take a while (they say 2-3 days) and you need a postal address in Thailand.
All management of the SIM card is made through their app available for iOS and Android. For payment it need to be linked to a VISA, MasterCard or a Rabbit Line Pay.
Data feature packages
All Line applications are free and basic data at low speed of max. 256 Kbps are for free as well as SMS. Fast data up to 100 Mbps are taken from one of these monthly combo plans which can be changed each month:
|Lite||5 GB||0 Mins||399 THB||189 THB|
|Special||20 GB||100 mins||499 THB||229 THB|
|Max||80 GB||300 mins||1099 THB||279 THB|
|Unlimited||U/L||U/L mins||1999 THB||499 THB|
For the packages marked with (#) a 50-70% discount shown as promotion in the table is given every month for max. 12 months.
For extra data you can add 1 GB at 60 THB.
