Prepaid Data SIM Card Wiki

T-Mobile US[]


T-Mobile US is the rising star among the “Big 3” providers. In 2019 a merger with Sprint was proposed and in 2020 approved by the authorities and courts. After the merger the New T-Mobile as it's called will be on par with its two major rivals Verizon and AT&T.

2G is on 1900 MHz up to EDGE speed. 3G is on 1700 MHz (AWS) and 1900 MHz up to DC-HSPA. 4G/LTE is on 1700 MHz (B4, B66), 700 MHz (B12) and 1900 MHz (B2). In 2017, they acquired spectrum on 600 MHz (B71) for LTE that will be used to enhance coverage (called 'extended coverage'). See Basics chapter for specifics and compatibility.

T-Mobile announced that from 2019, 5G is available "nationwide". For a start in late 2019 200 million people are covered by 5G on 600 MHz (n71). Note that most plans are open for 5G, but very few US-sold smartphones (and so far none from other parts of the world) are capable of this new frequency.

Availability and start-up[]

Their starter packs are called “activation kits” and consist of a SIM card and an explanation leaflet in English and Spanish. They are available online to be sent to an US postal address, at T-Mobile branded stores (locator) and other stores without ID. Note, that activation kits sold in T-Mobile stores need to be activated at time of purchase. You can not buy just the SIM card. Micro-, mini- and nano-SIMs are available.

The official price in stores is now a whopping $10 (plus local taxes) containing only about $3 credit. Stores such as Best Buy sell the SIM starter kits with prepaid value included at no extra charge. (E.g. a $50 value SIM kit includes a SIM card without extra charge). Some shops want to charge even higher prices or hefty fees for cutting. So it's a better idea to buy the SIM in advance by independent merchants on (search for “T-Mobile Activation Kit”), simcallus or that are also shipped overseas for a small fee to avoid being overcharged. As of November 2018, activated SIM cards are selling on eBay at around $10. They have often bought the activation kits at one of T-Mobile's many promotions for $1. But you can't rely on getting one for this start-up price in a T-Mobile shop and promo codes are only for online orders to be sent to an US postal address. Do not buy an un-activated T-Mobile SIM on eBay, etc. unless it includes a prepaid plan activation code. Without an activation code the SIM can't be activated on prepaid.


T-Mobile is shutting down its 2G and 3G networks for 4G/LTE and 5G. From August 2020 T-Mobile service is requested to check whether your BYOD is capable of their network by offering VoLTE before activation. Starting January 2021, phones without T-Mobile VoLTE support will be prohibited from being activated on the T-Mobile network. With a phone sold by T-Mobile you will be fine. But with an unsupported device by Xiaomi or Huawei which you bring into the country, you may have problems activating it on their network from 2021. We'll keep an eye on it and it's still unknown if this affects all MVNOs too.

The activation kit comes only with an activation code and without a number assigned to it. Activation is done by calling 877-778-2107 from any phone, *611 from T-Mobile phone or online HERE. This is where you can choose your number and plan too. Signing up can be done while you are in the US or before at home. You will get a text message for verification. This SMS used not to be forwarded abroad when roaming on a network other than T-Mobile US. Recently, first users succeeded in activating it through non-US roaming networks. So you might give it a try before leaving for the US.

In 2016 T-Mobile changed their policy and started to ship SIM cards already pre-activated on the $3 "pay as you go plan". This gives the advantage that you only have to change the plan, but the highly popular $30 plan (see below) becomes now only available to un-activated kits or at Walmart stores.

Recharges and validity[]

You can try to recharge T-Mobile online, but looks like it accepts only US-issued credit cards. Non-residents should use vouchers instead, called 'refill cards' available at T-Mobile stores, many supermarkets, gas stations, Walgreen’s and CVS drugstores, 7-Eleven and many other places. Minimum top-up value is $10.

For refill cards, be aware that you are likely to pay more than the 'face value' of refills in stores due to the recently-introduced '911 Prepaid Wireless Emergency Service Fee', which for example in Los Angeles is around $5.80 on a $30 refill.

For refills by (foreign) credit cards the online site Callingmart is a great source. They previously charged a 2% fee, but as of November 2018 this is waived, and they charge no taxes and accept PayPal too.

For recharge T-Mobile numbers directly without PIN codes you can try SwiftRecharge online portal. The portal allows to recharge any prepaid T-Mobile numbers with all type of bank cards and crypto currencies such as Bitcoin, Ethereum and USDT. Though there is small convenience fee will be applied.

The SIM card is valid for 90 days after the last refill. After 90 days since last recharge, it will be terminated and the remaining credits will be lost. Since 2014 T-Mobile has a $3 monthly minimum charge.

There is one exception to this termination rule and minimum charge: for iPads with LTE connectivity and other certified tablets too, T-Mobile offers a 200 MB per month free plan which doesn't expire after 90 days or charge a monthly fee. According to T-Mobile, these accounts expire after 365 consecutive days without any activity. Since free activity counts, you should use mobile data once per year to keep this free plan alive.

Re-activation of old SIM cards[]

It's verified that you can re-activate old T-Mobile SIM cards that have been terminated before and shut off. You can buy an T-Mobile Activation Code (without the SIM card) on eBay for a few $ and activate it online using your old expired T-Mobile SIM card. Thus, you will get a new number, but don't have to buy a new SIM card (at $20+) or obey expiry rules and waste money on useless monthly minimum charges.

You can also re-activate old T-Mobile SIM cards that are on the $3 per month Pay As You Go Plan by simply recharging the SIM card online with your T-Mobile web login. When you visit the US, just top up enough to pay for the $3 monthly charge and the data pass you want and then just let the plan lapse when you leave. DO NOT sign up for autopay or your account will always be charged when the balance goes below $0. Recharging $20 when arriving is usually enough to pay for the $3 minimum and then a $10 1 week 1GB data pass, with a few dollars left over for any voice calling you may want to do.

Default plan: "Pay as you go"[]

Their default rate for voice and data costs a $3 monthly fee. This includes 30 minutes voice (incoming or outgoing, domestic only) OR 30 text messages (domestic only). These two data passes can be added:

  • $5: 500 MB for 1 day (based on one calendar day on Pacific Time)
  • $10: 1 GB for 7 days

Activating one of the data packs can be done online at the "mobile" My Account site[1], in person at a T-Mobile store, or by calling customer service. The $10 data pack can be renewed within the 7 days when the data is used up (or before, but you lose any remaining data for that pass).

Monthly plan: Connect and Simply Prepaid[]

T-Mobile has multiple types of prepaid plans, all with unlimited texts and calls. Their cheapest type, T-Mobile Connect, was introduced in early 2020. It includes 2GB or 5GB depending on the plan, and unlimited calls and texts. Note that unlike their Simply Prepaid plans (and many other plans in the US), data is hard cut off after the data cap is used instead of slowed down. Their Simply Prepaid plans support eSIM on iPhone XS and later. If you want to use a different plan (or don’t have an iPhone), you can sign up for a plan at a T-Mobile store or their website.

Plan Name Cost Data
T-Mobile Connect 2GB $15 2GB (hotspot usage taken from data amount)
T-Mobile Connect 5GB $25 5GB (hotspot usage taken from data amount)
Simply Prepaid 10GB $40 10GB (hotspot usage taken from data amount)
Simply Prepaid Unlimited $50 Unlimited (hotspot usage at 3G speeds)
Simply Prepaid Unlimited Plus $60 Unlimited (10GB of dedicated hotspot usage, then usage at 3G speeds)

The Connect plans shut off data in the event of an overage, whereas the 10GB plan throttles data to 128kbps, and the unlimited plans deprioritize data after 50GB.

To reduce data consumption video streams are compressed and reduced to 480p quality. Their Data Maximizer is enabled by default on all plans, but users can disable at no charge on all plans except the Unlimited and Unlimited Plus plans. These users can't opt out of Data Maximizer but they can purchase 24 hour HD passes for $3. The HD passes provide un-throttled video streaming on the phone only, streaming over hotspot is throttled to 1.5 Mbps.

Plans renew automatically if there's sufficient balance to cover the monthly charge. When the plan renews the expiration date of any unused funds is extended 30 days.  If the balance is insufficient to renew the account will be suspended. You have 120 days to add money and restart the plan. After 120 days, the account will convert to the $3/month Pay As You Go plan for as long as the account has sufficient balance to renew.

The legacy daily Pay as you go plans have been discontinued in 2015.

Data-only plans[]

T-Mobile sells data-only packages too. They are called “Pay in Advance Mobile Internet” and don’t have voice or text. You can activate any un-activated starter pack to it, but once a SIM is activated to a phone, it's not eligible for data plans. Special starter kits are reduced to $10 for data-only SIM cards. These data plans advertised for non-telephony devices only as "tablet plans", but work in smartphones too without voice or text.

  • Data passes (on demand)
Price Data Period
$5 500 MB 1 day
$30 3 GB 30 days

These packs can be activated online on demand through your account and don’t renew themselves. One day is based on 0.00am-11.59pm in Pacific Time. They can also be added to a new SIM card for a $10 set-up price.

  • Monthly packs

Furthermore there are Simple Choice data only monthly packages (for 30 days) with automatical renewal. They include up to 5 GB data roaming in Canada and Mexico. Full LTE speeds are available up to the monthly allotment, including tethering, then service is slowed to "up to 2G speeds" for rest of service period. Prices do not include possible taxes and fees and a starter kit costs $10:

  • $10: 2 GB
  • $25: 6 GB
  • $40: 10 GB
  • $55: 14 GB

Metro by T-Mobile (rebranded from metroPCS)[]

new logo

Metro by T-Mobile, formerly under the brand MetroPCS used to be an own CDMA provider until it was acquired by T-Mobile in 2013. The parent company then moved customers from CDMA to its own GSM-based network. In June 2015, the CDMA network was shut down, but MetroPCS remained a separate brand reselling T-Mobile's GSM network in 2G, 3G and 4G/LTE (for coverage and frequencies see T-Mobile).

Since 2014, MetroPCS supported BYOP (Bring your own phone) of any T-Mobile capable, unlocked devices. In 2018, it was rebranded to 'metro by T-Mobile' with new offers added.

Start up[]

SIM cards for BYOP are available online to be sent to an US postal address or at metro stores and authorized dealers (locator) for $10 each, but not in branded T-Mobile stores. All SIM sizes are offered.

Recharge and Balance[]

Metro offers a number of ways to pay without surcharges: Online using a credit/debit card or a Metro payment card sold at Walmart, BestBuy and other retailers. For a fee of $2 you can use a 24-hour payment machine at a Metro store. For $3 you can top-up over the counter at a Metro store or authorized dealer. Alterantively, you can use online mobile top up portal such as Swiftrecharge, with a fee ranging from $1.99 to $3.99 depending on the amount you refill.

Check your balance and expiration date in the MyAccount section of the Metro website, using the MyMetro app on the phone or by calling *611 from your Metro phone, or 888-863-8768 from any phone.

You can activate monthly packages online, at a Metro store or an authorized dealer.

SIM swapping[]

Unlike other GSM operators, MetroPCS restricts users from switching SIMs between phones. SIM swaps are possible but require a call to the *228 or 611 automated voice response system or a visit to MetroPCS store to have the SIM linked to the new device. Stores may charge a fee to swap SIMs between to phones. As of late 2018 there are numerous reports of people being charged a $15 fee (plus tax) for putting their Metro SIM card in another device in a store.

To do a SIM swap using the automated voice response system: on the phone you want to swap the SIM from, dial *228 if it's a MetroPCS phone or 611 if it's a non-MetroPCS phone, at the first prompt, say "My Phone", then "Change Device", when prompted if you are using the same SIM, say "Yes", when prompted, enter the IMEI of the phone you are switching to and wait for the confirmation message, hang up and switch the SIM to the new phone.

Data packages[]

Metro by T-Mobile offers only monthly combo packages with unlimited US talk and text and this data quota:

  • $30: 2 GB data, hotspot use allowed
  • $40: 5 GB data, hotspot use allowed
  • $50: unlimited data, no hotspot use
  • $60: unlimited data, max. 10 GB hotspot use

Beyond the included data quota, speed will be throttled to 128 Kbit/s. On the unlimited data plans data speeds are subject to deprioritization after 35 GB when the network is congested. Beyond some customers may get slower speeds in times of congestion. Video streaming is always limited to 480p. For a $10 add-on, you can get HD.

Boost Mobile[]


Boost Mobile is a prepaid carrier once owned by Sprint, and has now been sold to Dish Wireless. As part of the T-Mobile and Sprint merger works, work is in progress to migrate customers off of the old Sprint-based system, and SIMs on the T-Mobile network are now available, so it can now be moved from the Sprint section to here.

Start up[]

Currently, "expanded network" SIMs (that use the T-Mobile network and are compatible with any devices that use T-Mobile frequency bands) are now being made available nationwide as a result of the Dish acquisition being completed. While some stores may still have older, Sprint-based SIMs ("expanded network" SIMs are orange, triple-cut, and only have the Boost Mobile logo, while old SIMs are white, single-cut nano size, and have logos for Sprint, Boost, and Virgin), most should carry the new SIMs.

As of June 2020 Boosts mentions these phones as compatible to their "expanded network": LG K51 and Stylo 5X,  Motorola Moto E6 and G7 Play, Samsung Galaxy A10e and A20 as well as all iPhones from series 6, preferably in the US version. The device must still be activated by a dealer in a store. The pop and swap functionality will be available at another time. More info can be found here: hbring-your-phone.html

This costs $10 plus local taxes. Some franchised Boost stores may want to charge more, either increasing the price of the SIM or charging an "in-store service" fee on top. While this can be avoided by buying a starter kit at a retail store like Best Buy or Target, There is a way to tell if you will get a new or old SIM in the starter kit,old sim kits have the terms "Nationwide Network" and the older Boost logo as shown above on the packaging. The new expanded network SIM cards have the letters "TN" on the SIM card itself and the logo is the new boost logo with the combined Dish symbol. Only do this if you have a phone that is also compatible with the old Sprint-based system.

Validity for a Boost SIM is 90 days from last monthly plan top-up. Each time you pay for a month of service, you get that month's service, and if you do not top up for the next month's service by the next due date, you will continue to be able to receive incoming calls and SMS for 60 days, after which the SIM will deactivate and you will lose your plan and number.

Monthly Plans[]

Boost has two plans with limited data and two unlimited plans with varying amounts of tethering data available:

  • $30: unlimited domestic voice/SMS and 2 GB
  • $35: unlimited domestic voice/SMS and 3 GB
  • $35: unlimited domestic voice/SMS and 10 GB (hard cap)
  • $45: unlimited domestic voice/SMS and 15 GB
  • $50: unlimited domestic voice/SMS/data, 12 GB mobile tethering
  • $60: unlimited domestic voice/SMS/data, 30 GB mobile tethering

Taxes and fees are included in the above prices. Streaming video is throttled to 480p quality on all except the $60 plan. On plans with limited high-speed data, music streaming with these services is zero rated. The difference between the two $35 plans is that the 3 GB plan offers unlimited data at 128kbps after the cap is reached, while the 10 GB plan will cut off data after the cap is reached.

For plans with limited high-speed data, additional high-speed data can be purchased online once you have set up a My Boost account for the following prices:

  • $5 for 1 GB
  • $10 for 2 GB


There is one package available for international roaming, to Mexico only. The $5 Todo Mexico Plus add-on allows for unlimited voice, SMS, and up to 8 GB data roaming in Mexico depending on your plan.

All packages will renew automatically, if there is credit. If you do not have sufficient funds in your account to renew your service will be suspended. Unused call credits rollover provided you top up on time before the account is deactivated for inactivity.

Pay-as-you-go plan []

Their pay-as-you-go rate outside of monthly packages doesn't offer data or MMS. Current Lycamobile monthly plan users can switch to the pay-as-you-go plan only by adding a $10 top-up and letting their plan expire. It's the least expensive way to park a phone number as regular top-ups aren't needed. This plan is not mentioned on their website. Funds added to a Lycamobile pay-as-you-go account never expire as long as a non-toll-free call is made or received or a text is sent at least every 60 days. That means, it can cost less than 30¢ a year to keep a SIM alive.
