Abstract

A system and method for transmitting user data between personal communication devices is disclosed. User data may be electronically transmitted between personal communication devices using hardwired interfaces, optical interfaces, and cellular communication networks. User data may also be stored in a cellular communications network for electronic transmission between the network and personal communication devices as desired.

Claims

1. A method for transmitting user data between cellular telephones that have been activated on different cellular communication network carriers comprising:

selecting a first cellular telephone activated on a first cellular communication network carrier;

identifying user data stored in memory of said first cellular telephone for transmission;

encoding the identified user data at said first cellular telephone;

transmitting the identified user data via radio frequency (RF) signals from said first cellular telephone to the first cellular communication network for storage;

transferring the identified user data stored in the first cellular communication network to a second cellular communication network for storage;

selecting a second cellular telephone activated on the second cellular communication network carrier, wherein the second cellular communication network carrier is different than said first cellular communication network carrier, for reception of the identified user data;

transmitting the identified user data from said cellular communication network to said second cellular telephone;

decoding the transmitted user data at said second cellular telephone; and

storing the transmitted user data in memory of said second cellular telephone.

2. The method of claim 1 wherein the selecting step includes entering into the first cellular telephone a cellular telephone number corresponding to the second cellular telephone.

3. The method of claim 1, wherein the identified user data stored in memory of said first cellular telephone is automatically periodically transmitted to said cellular communication network.

4. The method of claim 1, wherein the identified user data is password protected.
