SIM card
When you register as a subscriber with a network operator,
you get a SIM (Subscriber Identity Module) card. The SIM
card keeps track of your phone number, the services
included in your subscription, and your contact information,
among other things.
If you have been using a SIM card in another phone,
make sure that your information is saved to the SIM
card before you remove it from the other phone.
