Abstract
An Easy Activation sequence for cellular phones that includes a checking code calculation feature which enables a phone owner or user to safely carry out operator assisted NAM programming activation locally in the phone independent of the support provided by the network. The user need only key in a MIN, SID, and checksum in response to appropriate prompts and obtain an indication of whether the NAM programming has been correct or not. Various other parameters, such as A-key and alphanumeric SID, may also be accomodated.
