The SIM card 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 $0.25 surcharge to all calls made to the US 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. Either speak to a live rep (toll free) or enter a short sequence on your handset to add call credit.

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

Activating Your Service:
Simply make a call in order to activate your International SIM card. Your service is valid for 12 months from the day of activation. Recharging your SIM card (adding talk time), extends the validity for another 12 months from the day you add the credit.  Please note that while the service does work in North America (in areas with GSM coverage), the service is intended for use overseas and therefore, placing a call from your handset in North America is expensive.

Your Phone Number:
You will have a UK phone number, regardless of where you are traveling. Your phone number will be clearly marked on the SIM card packaging.

Checking Your Credit:
You may check your credit at any time by dialing 187 on your handset. This is a free service. You will receive a text message with your current credit. You will also receive an SMS text message after each call notifying you of your current credit.

Adding Talk Time to Your SIM Card:
You can add talk time at any time - together with your purchase as well as prior to and during your trip. Simply call on our phone number included in package and we will immediately add talk time for you using your account information already on file or an alternative credit card. Additional call credit is $29 for 30 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.


Making and Receiving Calls:
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.

Voice mail:
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 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.

SMS:
You can send and receive SMS text messages from your international cell phone. However, we nor any carrier 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.

Other SIM Cards:
If you should choose to buy a Package , you are not "locked" into only using the SIM card that comes with the package. If you would like to use a Country Specific SIM Card in your phone, you may do so. (Obviously, if you have an unlocked GSM phone, the card will not prevent you from using other SIM cards in your phone.)

A Country-Specific SIM Card is usually advantageous if you plan to spend a certain portion of your trip in a specific country (or countries) in order to take advantage of that country's rates, usually including unlimited free incoming calls. Please click here for a list of our Country Specific SIM Cards.

Service Life:
The service life of your SIM card is 12 months from last use. You will need to have call credit on your prepaid account to make or receive calls or use value-added services like balance and voicemail retrieval. To extend the life of the card another 12 months, you must make or receive a call or send an SMS message.
