Abstract
An apparatus capable of providing multiple telephone numbers for a cellular phone includes a central processing unit connected to a random access memory and two erasable memories. One of the erasable memories stores common data of all the telephone numbers. The other one of the erasable memories stores non-common data. The central processing unit is provided with an external bus and two input ports coupled to the cellular telephone. One of the input ports receives a reset signal from the cellular telephone so as to control switching of the telephone numbers.
