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.

Claims

1. An apparatus capable of providing multiple telephone numbers for a cellular telephone, comprising:

a central processing unit having an input port;

a first erasable memory connected to said central processing unit for storing common data;

a second erasable memory connected to said central processing memory for storing non-common data; and

a random access memory connected to said central processing unit;

wherein said input port receives a reset signal so as to control switching of the telephone numbers.

2. The apparatus as claimed in claim 1, wherein the common data includes a phone book and short messages.

3. A cellular telephone integrated circuit card, comprising:

a central processing unit having an input port; and

a memory connected to said central processing unit for storing common and non-common data;

wherein said input port receives a reset signal so as to control switching of telephone numbers.

4. The cellular telephone integrated circuit card as claimed in claim 3, wherein the common data includes a phone book and short messages.

5. A cellular telephone, comprising:

a telephone;

a central processing unit having an input port that is connected to said telephone; and

a memory connected to said central processing unit for storing common and non-common data;

wherein said input port receives a reset signal from said telephone so as to control switching of telephone numbers.

6. The cellular telephone as claimed in claim 5, wherein the common data includes a phone book and short messages.
