ABSTRACT:
An end-user communicating device and method for enabling a user-selected communications carrier network to download data into a RAM within the end-user communicating device in response to a telephone call initiated by a user of the end-user communicating device to the carrier network to access a database within the carrier network. The data includes a carrier access code that is used to establish intraLATA toll calls and exchange numbers included in an intraLATA toll calling area associated with origination information obtained during the telephone call, such as the telephone number of the end-user communicating device. The end-user communicating device prepends the carrier access code to subsequently dialed telephone numbers that contain one of the exchange numbers included in the intraLATA toll calling area. If the data is corrupted, the telephone number of the carrier network is retrieved from a ROM within the end-user communicating device and dialed to refresh the memory of the end-user communicating device.
