MC75A6 - GSM Configuration 5 - 3
MC75A6 Service Verification
MC75A6 phone and data services require a live SIM card, obtained from a service provider, installed in the MC75A
phone. The SIM card has embedded circuitry on one side of its surface which, when inserted into an MC75A
phone, provides phone service. The SIM card provides a phone number, determines the features or services
available to the subscriber, and identifies the subscriber to the network.
In addition to SIM card installation, the MC75A may require various settings to operate as a phone with data
connection features.
Ensuring Network Coverage
1. Ensure an activated SIM card, from the phone service provider, is installed in the MC75A.
