A Subscriber Identity Module (SIM) is a removable card for cell phones that use the GSM (Global System for Mobile communications) mobile network. The SIM card allows users to change phones by simply removing the SIM card from one cell phone and inserting it into another cell phone.

An unlocked cell phone is not tied to any particular phone network. You can insert any SIM card into an unlocked phone and connect to the appropriate phone network operator. Your phone may be locked if it was not purchased from us. To check if your phone is locked, call your mobile service provider.

No. With SIMsmart USA there are no contracts and no minimum commitment required.
