All countries

There are international SIM cards on the market offering "worldwide" data roaming or at least in major regions. Their offers are collected here in this "all countries" section. Their data rates are often more expensive than on the national level. So always compare with local SIM cards and roaming offers in your country. Although you won't save much using these cards, they may be a good option for frequent travelers and people travelling through multiple countries. For Europe alone, check the European Union section too.

''For a better readability this article is split into two separate parts now. This first part below is dedicated to international (data) SIM card offers. In a second article travel combo packages with Wi-Fi hotspot rental or purchase combined with a worldwide data plan are listed.''

PART 1: Worldwide Data SIM Cards
The data SIM-only approach has the main advantage, that you can use your own gear. You don't need to buy or rent and learn how to handle another device. But you need to be sure, that your device works on the frequencies employed in this country. So check compartibilty of your mobile with the bands offered in your destination before you start your journey. Compared to offers that include a WiFi router they are harder to share between devices and are priced higher for data than WiFi combo plans, for which you'll have to pay extra for the hardware.

TravelSim
TravelSim is one of the oldest and most established companies to have launched an international prepaid card, using an Estonian (+372) number. It has voice and text service in about 190 countries and proved to be quite reliable.

The only problem has been its very high cost for data. If you travel a lot and always go to different countries it can be much more comfortable to use only one prepaid number which can be used (almost) worldwide. But this has an extra price.

In 2016 they lowered some data prices and scrapped their data card. They now offer only one product for voice, text and data with lower rates, but a higher start-up price.

Start-up price and availability
The TravelSim card is only available online on their website with worldwide free shipping. It costs 75 EUR with 50 EUR credit and comes as micro-, mini- or nano-SIM. It can be reloaded by international credit cards on your TravelSim online account and stays vaild for 2 years after the last top-up.

Validity
Unlike voice and text, data is only available in about 100 countries and 2G and 3G only. The rates range from crazy 10 EUR to 0.19 EUR per MB depending on the country. The price model is split into 2 schemes: a pay-as-you-go rate and package rates.

Pay-as-you-go rate
It's the default rate when no pack is booked and the only rate for some countries. Rates are charged in 1 KB or 10 KB increments and the most important countries are:
 * 0.19 EUR per MB: in the most of Europe, Brazil, China, Australia, India, Indonesia, Israel, Japan, Korea, Turkey, Thailand, Taiwan, USA, Canada
 * 0.39 EUR per MB: in Serbia, Turkey
 * 0.59 EUR per MB: in South Africa
 * 10 EUR per MB: in many countries in Latin America, Africa and Asia
 * see new price survey (click on data rates)

Data packages
Furthermore, they now offer these new data roaming packs: To book a package type *146*941* #. To deactivate *146*940* # and *146*942* # to check the status of service. Data packages can be used in following countries: Argentina, Australia, Austria, Azerbaijan, Belgium, Brazil, Bulgaria, Canada, Chile,  China, Colombia, Costa Rica, Croatia, Cyprus, Czech Rep., Denmark, El Salvador, Estonia, Faroe Islands, Finland, France, Georgia, Germany, Gibraltar, Greece, Greenland, Guatemala, Honduras, Hong Kong, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Japan, Kazakhstan, Korea (South), Kosovo, Kuwait, Latvia, Lithuania, Luxembourg, Macedonia, Malaysia. Malta, Mexico, Monaco, Netherlands, Nicaragua, Nigeria, Norway, Panama, Paraguay, Peru, Poland, Portugal, Puerto Rico, Qatar, Romania, Russia, Saudi Arabia, Serbia, Singapore, Slovakia, Slovenia, Spain, Sri Lanka, Sweden, Switzerland, Taiwan, Tajikistan, Thailand, Turkey, UAE, UK, Uruguay, USA. In other countries data roaming may be possible, but only on pay-as-you-go rates (see above).

Only one package can be activated at once. A data package is activated as soon as the order through USSD-command is made (even in the country not listed above). The package cost is taken immediately. The package is completed either when the ordered amount of data is used, or when duration time is reached. It's possible to order a new data package when the data amount has been finished, despite the duration time of this package. If the amount of data hasn’t been used, the client can't order a new package. To order a new package the current one has to be deactivated with USSD-command. In case of deactivation, unused amount of data will expire and money will not be refunded. Daily AUTO package is activated only when data session is initiated in one of the countries from the list. The package cost is taken from user’s balance immediately when Daily AUTO package is activated. If customer uses data in one of the countries next day, the Daily AUTO package will resume its service automatically and the packagecost is taken immediately from user’s balance.

More Info
The rates are surely above the prices of average national data SIM cards. But there is hardly one product comparable on the market. Other international roaming cards like XXSIM and Maxroam don't offer so low prices for worldwide data, that's why they are out of the list. It depends on how much you are willing to pay extra for an almost worldwide solution. Always compare the TravelSim rates with the roaming rates of other mobile providers.

As calling an Estonian mobile number can be expensive TravelSIM made a deal with the VoIP providers Skype and Viber that can be activated by *146*711# for free. When the feature is activated, Skype and Viber users can call the TravelSim number for free using special dialing format +372 800 XXXXXXXX, where XXXXXXXX is a TravelSim number without the prefix 372. The call is free for the Skype and Viber user, but the TravelSim user still has to pay for an incoming call.

OneSimCard
On the other side of the Atlantic OneSimCard by Belmont Telecom Inc. offers a very similar product. Its "data & roam" SIM works in 160+ countries, is also based on an Estonian number (+372) which is added by a US or Canadian number and has essentially the same rates like TravelSIM.

The main difference is the underlying currency of US$ instead of Euro. The SIM costs $29.95 with free shipping in the US and the tariff table is identical to TravelSIM: The PAYG rate of 0.19€ is $0.25, 0.39€ is $0.50 going up to 20€ or $25. They also sell totally the same data packages for the equivalent rates in US$. Although data of some countries are not counted twice in the packages like with TravelSIM, they simply cut in half the allowances of the (2x) countries, which is the same in the end. For more info see TravelSIM above or check their website. If you live in America, it might be the closer choice for you to get the same SIM plan.

XXSim
Like TravelSim XXSim is a reliable international SIM card based on an Estonian (+372) number which has been around for years. In fact, both products use the same platform. Voice is available in about 190 countries and data in a few less. While TravelSim has issued a data card, XXSim has not (yet). XXSim offers the exact same data prices given above at the pay-as-you-go-rate, but they don't offer any packages though.

That's why XXSim can't be recommended. First you pay the premium of an international SIM card, but you don't get the discounts of TravelSim. Charging 0.19 EUR per MB within the EU, you are almost at the price cap for any SIM card sold in the EU with roaming data. So for many users the roaming option of your home carrier is the more convenient choice at the same price, while TravelSim is the cheaper alternative if you want to buy an international card.

Piranha Mobile
Piranha is an international SIM card coming with an US (+1) and an UK (+44) mobile number. It offers prices below TravelSIM at the cost of less reliability and comfort.

Start-up price and availability
The starter pack is available only online as mini-, micro- or nano-card in three denominations with free international shipping: Top ups can be made online with credit card or PayPal. Auto top-up can be linked to a credit card.
 * SIM card with £5, credit: £12
 * SIM card with £30, credit: £35
 * SIM card with £50, credit: £50

Generally, they offer good rates on voice, text and data, but the rates are as complicated as the technical settings. Most calls are made through the callback procedure. In tests, the card proved to be very reliable:

Data rates
For data, they offer roaming in about 140 countries. It is billed in 50 KB increments. Rates differ even in the same country, depending on which local roaming network you are on. Some price examples: Because of different rates for different providers in the same country, be sure to pick the cheapest first and disable automatic network selection, so your device can't switch the roaming networks. Furthermore, Piranha mobile allows you to make calls through VoIP if you install their VoIP app or have a VoIP-router and Wifi connection.
 * 0.07 € - 0.14 €/MB: all EU/EEA states
 * 0.08 €/MB: USA (T-Mobile)
 * 0.11 €/MB: Turkey (Avea, Vodafone)

KnowRoaming
KnowRoaming is a Canadian start-up with a new approach: They provide a "SIM sticker" which has to be applied to your home SIM. Thus, all calls, texts and data outside of your home market are diverted through the KnowRoaming SIM addon. Their sticker intercepts electrical signals before they go to the regular SIM. If you're in your "home" country it passes everything through. Otherwise it "takes over" and functions as a second SIM. They claim that this sticker will fit over regular, micro and nano SIMs.

What they don't say is that e.g. Apple denies all warranty, if the SIM-card-holder is damaged by manipulated SIM-cards. The first feedback by users e.g. on Amazon seems to be mostly positive, but some had problems using the sticker.

Startup price and availability
The SIM sticker is only available online on http://www.knowroaming.com with worldwide free shipping. It costs $29.99 with $10 credit and comes with an applicator for micro-, mini- or nano-SIM. The SIM addon can only be managed and reloaded by their app available for Android, iOS and Windows Phone.

Validity
Their SIM card will be terminated after 15 months of inactivity. Data is available in about 80 countries and 2G and 3G only. The data rates range from $0.15 to $0.65 per MB depending on the country. Like TravelSIM, the price model is split into two tariff lines: a pay-as-you-go rate and a package rate.

Pay-as-you-go Rate
It's the default rate and the only rate for some countries. Here are some examples:
 * $0.10 per MB: USA
 * $0.15 per MB: all countries of the EU/EEA, Australia, Canada, Singapore, South Africa, South Korea, Switzerland, Turkey

see full prices here
 * $0.20 per MB: Argentina, Hong Kong, India, Israel
 * $0.25 per MB: Brazil, Mexico, UAE
 * $0.30 per MB: China, Russia, Thailand
 * $0.35 per MB: Japan

Data Packages
Furthermore, they offer the following data pack to be booked by app: In their T&Cs they state a Fair Use Policy, that they can throttle speed to 258 kbps after having reached only 250 MB per day.
 * "Unlimited" data for $7.99 per day. This pack is only valid in all EU/EEA countries, Albania, Armenia, Island, Macedonia, Russia, Serbia, Switzerland, Ukraine, Mexico, USA, Hong Kong, Israel, Japan, Singapore, Thailand, South Korea, Kazakhstan, Ghana, South Africa, Australia, New Zealand and a few more

Countries and rates
They offer three different packages: All packages are valid for 30 days. Note that the rates above don't include taxes. You need to add the VAT according to your country. Have in mind, that holding a Zone 3 package, you'll surf on this expensive rate in Europe (= Zone 1) too.

GigSky (and Apple SIM)
GigSky is an US-American company based in California, which runs a world data SIM with data-only services in more than 90 countries so far, but no voice or text available. Data is generally on 4G/LTE, which is a strength compared to other SIM cards, but is 3G still in some countries.

Availability
You can take a SIM card buying it on Amazon.com with worldwide delivery or by their own supplier. Delivery is free to most countries in North America, Europe and some Asian countries, but can be up to $44.95 elsewhere. Expect 1-30 days for delivery depeding on destination country.

The SIM card is sold for USD $20 in mini, micro and nano size with 100 MB data included and it will not expire. Top-ups are by credit card on your personal account.

Data Rates
The data rates depends on the country which you want to travel. The base table is:

It's recommended to go to their pricelist hidden on their website to check the correct rates for your destination, though. Some countries are cheaper like many EU countries, some exotic countries are more expensive.

Note, that you will need to purchase a separate data bundle for each country visited to have data. It will not roll over to the next country, even within the same rate. This is a huge setback for an "international" solution.

Apple SIM
Apple has teamed up with GigSky and sells their Apple SIM in iStores of 13 countries only or with a certified iPad (see restrictions). It offers data access to 140 countries. Rates and tariffs are the same like GigSky.

ComfortWay
The Russian ComfortWay company has become the first to implement Remote SIM Provisioning specification and produce its own carrier agnostic SIM in 2016. The main advantage of this so-called CwSim comparing to traditional SIM cards is being associated not only with one network operator, but receiving and using profiles of many different operators depending on the location. It has coverage in 140+ countries so far.

This virtual SIM-card technology allows selecting a data plan of any local mobile operator in one click via the ComfortWay mobile app. ComfortWay has developed the technology of secure downloading of mobile profiles "over the air".

Availability
The CwSim card is officially available for purchase at the price of 990 Rubles since August 2016. It's possible to buy it from the ComfortWay distributors listed on the official site. But they seem to still have some problems with distribution.

Data rates
In 41 countries they offer 1 GB data at 5-10 €, in 16 countries at 12-19 € and in 39 countries at 20-29 €. Their data packages are offered as: In 26 further countries only a 150 MB per day at 5 € and in another 16 countries at 8 € are offered.

ChatSIM
ChatSIM, formerly known as WhatSIM, is the first international roaming SIM card aimed at social messenger users only. This Estonian-based SIM by the Italian MVNO Zeromobile roams in 400 networks of around 150 countries. It supports major messengers like Telegram, WhatsApp, BBM, Facebook Messenger, WeChat, Line, QQi and Kakao, Kik and Hike.

The SIM card needs to be ordered online on their website. They charge 20 € for the SIM and at least 5 € for shipping. All three SIM sizes are available. When you get the SIM, it needs to be activated online. For a 10 € charge included in the starter price, you can chat for one year in all covered countries. But this refers only to text and emoticons, not other types of messages like pictures or videos.

For multimedia contents like photos, video or audio, a price scheme based on credits and zones is in place. To send multimedia messenges or make VoIP calls, you need to top up at least 10 € as well as for all other internet browsing. The zoning starts at 50 credits (= 0.25 €) per MB in the EU which is even above the EU data cap. It goes up to 750 credits (= 3.75 €) per MB in exotic countries. All multimedia content and surfing other than text messenging are charged accordingly. VoIP or other calls through the messengers are possible, but billed likewise. Voice calls and SMS are not supported.

Reloads are by credit card on their website. It will not expire, as long as you use it once within 12 months and top up 10 € every year. You need to switch off data traffic on all mobile apps on your device as long as you don't add extra credit because your SIM will blocked, if anything else but text messenging is detected and you don't have credits. So better think twice about this SIM even if you are a chat fanatic.
