Listen to an Overview


With the National Geographic Talk Abroad® Travel SIM, we make international cellular service easy and affordable for anyone traveling overseas. This SIM card is compatible with any unlocked GSM cell phone with the appropriate GSM bands. The SIM has two phone numbers, a US based number as well as a UK based number. Both numbers are always active and do not require a monthly fee. Incoming calls on the UK number are free in more than 70 countries. There is a $0.30 per minute charge to all calls made to the U.S.-based number.

You can forward your US or Canadian number to the US number and get the same benefits as roaming without the fees! Or, you can give some of your contacts your new US number and other contacts your UK number. Adding additional talk time is a snap. You may opt for our 'auto recharge' option which automatically adds $29.00 of credit whenever your balance runs less than $10.00, or you can even simply enter a 5-digit code on your handset to add call credit.

The Talk Abroad network also supports data functions, so if you need a data solution that works in 130+ countries, with 3G speed available in over 70 popular destinations, the National Geographic Talk Abroad Travel SIM Card is an excellent value.

National Geographic Talk Abroad® Travel SIM is available in standard, micro and nano sizes. Most iPhone 4 and 4s as well as the Samsung Galaxy use micro SIM cards while the iPhone 5 and 6 use the nano SIM card. If you order a micro or nano SIM card, we will include a set of SIM card adapters and a tool kit. The adapters will allow you to adapt the SIM card to a standard size, just in case you need to put the SIM card in a different phone, and the SIM card tool makes opening the SIM card tray so you can swap out the SIMs a snap.

Whether you are a frequent business traveler or a tourist seeking a reliable yet affordable calling solution, the National Geographic Talk Abroad® Travel SIM will cover you in over 200 countries. Since this is a prepaid solution, there are no contracts to sign or monthly bills - ever!

Frequently Asked Questions for The National Geographic Travel SIM Card

Why is the National Geographic Travel SIM the best SIM card available for roaming?
There are several other SIM cards on the market. The Nat Geo SIM has a reputation for reliability and transparency in terms of rates and features. We do not cut corners on customer service nor on cellular service which is not often the case in the roaming SIM card business. We are certain that you will agree with us that the National Geographic Travel SIM is the best SIM available on the market.

What are the rates for the National Geographic SIM card?
For the latest rates, please click on the "Call Rates" or "Data Rates" tabs.

I just need an international SIM card with data. Is this the best travel SIM card for me?
SIM cards that are dedicated only to data tend to have better rates than SIM cards that are data and voice. If you need a data only SIM card for global use, for example, for your tablet or you just simply do not need to make and receive phone calls (or you can use data for you calls through Skype, Whatsap or similar), please visit this link Here you will find data SIM cards for global use that you can use virtually worldwide as well as SIM cards intended for use in one country which usually offer much better rates than international roaming data SIM cards.

Is there a better SIM card for international use than a global roaming SIM?
Potentially, yes. If you are traveling only to one country, it makes sense to get a local SIM card. For example, if you are going just to Italy or just to the UK, then get a local SIM card. Cellular Abroad offers many local SIM cards for popular destinations, including Italy, the UK and many others. You may also be able to get a SIM card when you arrive but, not only is it more convenient buying one before your trip, if you do not speak the local language, you may have a very challenging time trying to use the SIM card. Also, in some countries, you cannot buy a SIM card unless you have a local residence. What many of our customers do is to use the National Geographic SIM card as a backup in case they cannot locate a local SIM card in the country to where there are traveling. Or, if they are only in that country a few days or don't make a lot of calls, than they just use the Nat Geo SIM. In sum, the National Geographic global SIM card, while it does work around the world, is more expensive but more convenient than getting a local SIM card.

What cell phones use SIM cards?
Virtually every newer cell phone has a slot for a SIM card. Having said that, many carriers, including Verizon and Sprint, use a technology in the United States that does not require a SIM card. Most of their phones are hybrids and use the CDMA technology stateside and the GSM technology, which requires a SIM card, internationally. Unless your phone is an older phone or an entry level phone, it should have a location for a SIM card. Check with your provider to make sure that it has the proper GSM networks. Another requirement is that your phone is unlocked.

What is an unlocked phone?
An unlocked cell phone is a cell phone that allows you to put any carrier's SIM card in and work. Cell phones come out of the factory compatible with any carrier. However, since many carriers subsidize the price of the phone, they "lock" them so that they can only work on their network. Basically, the carrier is saying, "I will give you a phone at a lower cost but you can only use your phone with our company." After your contract is up with them, usually 2 years or so OR, if you pay off the rest of the subsidy, they will unlock the phone. In addition, some carriers, notably Verizon, does not lock their high end phones to begin with.

Will I get 3G or 4G data speeds internationally?
Virtually all international carriers offer 3G data speeds oversees. Some carriers do offer 4G speeds, and you may even get 4G speeds at times, but typically, 4G is allocated to local SIM cards when and if available

What is the difference between a micro SIM card and a nano SIM card?
The quick answer is, very little in terms of size but a lot in terms of compatibility. The nano SIM card is just a small fraction smaller than the micro SIM card but if you try to put a micro SIM card into a nano sized SIM tray, it won't fit, and vice versa. You can get an adapter to adapt up from a nano SIM card to a micro or even standard SIM card but of course, you cannot adapt down. If you SIM card size it too large, you can manually cut it (there are vides on Youtube showing how to do this) or you can purchase a cutter online.

What is a mini SIM card?
Some phones refer to the SIM card size as mini. A mini SIM card is also known as the standard size SIM card. In the 90's, there were phones that took SIM cards that were the size of a credit card and hence, when the smaller size came out, what we now refer to as a standard size SIM was referred to as the mini SIM. Some phone manufacturers still use this antiquated nomenclature which, admittedly, adds to the confusion.

Will I have to put in any settings on my phone in order to use the SIM card?
If you plan on using data then yes, you will have to change the APN on your phone as per the information provided with your SIM card. This is typically easy to access in your phone's settings. Please refer to the instruction guide for your phone or, better yet, go online to view a step by step either video or webpage that shows you exactly how to do this.

How do I Activate My SIM Card?
Simply make a call or a text message in order to activate your Talk Abroad™ International SIM card. Your service is valid for 12 months from the day of activation.

How Long is the SIM Valid?
As long as you turn on your cell phone or tablet before 12 months expire and it picks up a network, your service will be extended for an additional 12 months. You can do this as long as you are in a GSM coverage area - even in the United States or Canada.

What is My Phone Number?
You will have U.K. and U.S. phone numbers, regardless of where you are traveling. Your phone numbers are emailed to you the same day your order ships, typically same or next business day for purchases, and will be clearly marked on you invoice. While you can receive calls and text messages on either number, you can only make calls or text messages from your UK phone number.

How Do I Check My Credit?
You may check your credit at any time by dialing *187# on your handset for free. You can also check your credit online. You will receive a text message with your current credit.

How Do I Add Credit?
You can add talk time at any time - together with your purchase as well as prior to and during your trip. Choose the "Auto-credit top-up" option during checkout to enable your credit to be recharged automatically every time your credit drops below $10.00. Alternatively, you can add $29 to your account at any time while traveling, instantly, by dialing *161# send from your handset. Additional call credit is $29 for roughly 42 minutes of talk time (for most popular destinations). Each time you add call credit or "recharge" your account, you will extend your service life for an additional 12 months from the date of the recharge. Previous call credit will accumulate to your new call credit.

How Are the Calls Charged?
When you make a call, charges begin only when the other party answers the call or if the call goes to voicemail. Outgoing and incoming call charges, where applicable, are based on 60-second intervals.

Is There Voice Mail?
Yes, your National Geographic SIM Card has voicemail capabilities.

Your voice mail is already activated. You can access your voice mail system from your handset. It's the cost of a call to the UK from your location. From your handset, you dial a 3 digit number as per our instructions and follow the prompts to listen to messages. You will receive a text message alerting you of any new voicemails.

Can I Text?
You can send and receive SMS text messages from your Talk Abroad® international cell phone to and from your UK number. However, we nor any carrier, can be responsible nor guarantee that you will always be able to send and receive SMS messages in all circumstances and in all countries. SMS text messages are free to receive and are $0.60 to send, regardless of the country.

Does the SIM Card Have Data Capabilities?
Data services are now available for all Talk Abroad service users. Our rates are listed per megabyte, but we bill your prepaid credit for each 100kb - so if you only use 100KB of data, you will only be billed 1/10 of the per megabyte rate listed in the table below.

As an example, if you are traveling to Germany, the rate is $1.04 per MB - so if you use only 100kb, you will be billed roughly $0.10. One recharge ($29) will get you around 28MB of data in Germany.

To set up data, all you need to do is set your APN to "mobiledata" - this can be done in your phone's connection settings. You can set this up on your phone using our Data Service Guide.

Due to the way they are manufactured, RIM Blackberry model handsets are not compatible with our data services.
