ABSTRACT:
A telephone includes a SIM card reader which receives SIM cards. The SIM card may contain two or more telephone numbers for which the phone is activated. One of the numbers may be a temporary number which is linked in use to, for example, a time period. By providing the capability of having two or more numbers on a SIM card, a single phone may respond to incoming calls for a different number of telephone numbers.
