ABSTRACT:
The present invention provides a one button cellular phone that provides all basic phone functions using single button on the phone. The invention operates by the user pressing the single button to dial a service provider. The call then is answered by the service provider, thus connecting the single button cellular phone to the service provider. At this time, the user communicates a desired number to be called to the service provider. The service provider then connects the one button cellular phone to the desired number. The single button on the cellular phone can also be used to answer an incoming call and also to terminate a call in progress. The single button cellular phone of the present invention is easy to use and is especially advantageous for children, aged people and the disabled. By requiring only a single button and not the conventional 12 key keypad, the cellular phone of the present invention can be manufactured relatively small in size.
