Prepaid SIM Cards and GSM Cell Phones for International Travel

 
Prepaid SIM Cards and GSM Cell Phones for International Travel
If you are using a T-Mobile or AT&T cell phone, chances are that your handset is equipped with a SIM card. A SIM card is a small smart chip that acts as an identification card for your GSM handset. Your SIM card is smart because it can store phone numbers and even text messages. All SIM cards have unique serial numbers that contain your account information for your wireless service provider. You can take the SIM card out of your GSM phone, and it insert into any other compatible GSM phone, and bingo - your number along with your subscriber information will register with your  wireless service provider. You may already own an original or aftermarket cell phone that you purchased while traveling overseas. If your phone is tri-band or quad-band, it is capable of international mobile roaming. All you need is prepaid GSM service and you're good to go to any of the 150 countries we cover.
