Abstract
A system for user-programming of system parameters of a cellular telephone. Data values for the system parameters are stored in a nonvolatile memory within the cellular telephone. A password storage area stores one or more predetermined passwords. After purchasing the telephone, the end-user calls a predetermined telephone number and receives one of the predetermined passwords. The user enables a programming mode and enters the predetermined password using the cellular telephone keypad. If the user-entered password matches the stored predetermined password, the cellular telephone allows user access to at least a portion of the system parameters in the nonvolatile memory. A counter tracks the number of user-programming attempts and terminates the programming after either a predetermined number of failures or successful programming of all the desired system parameter values.
