Cellular communications device
First Claim
1. A cellular communications device for use with a cellular communications network, comprising:
- selecting means for allowing a user to select a number to be called;
a controller for controlling communication operations of the cellular communications device and for receiving the selected number from the selecting means;
a SIM comprising;
a memory for storing an access code;
means for receiving some or all of the digits of the selected number from the controller, modifying means for appending the stored access code to the selected number to provide a modified number, and means for forwarding the modified number to the controller; and
transmitting means for transmitting the modified number to the cellular communications network.

Abstract
A communications system for routing calls originating in a cellular communications network of the system. A cellular communications device, e.g. a mobile telephone, appends a stored access code to a user-selected number and transmits the resulting modified number to the cellular communications network. The SIM of the communications device receives a user-selected number from a controller of the cellular communications device, appends the stored access code to the selected number, and returns the modified number to the processor of the cellular communications device for transmission to the network. The call is then routed in dependence upon the appended access code. The call can be routed to a routing switch when then determines an appropriate route for the call.
