A cellular radiotelephone system (10) includes mobile stations (28) which may be remotely programmed from a customer activation system (12) to effect activation and other programming needs. Mobile stations (28) are manufactured in a blank form that causes them to operate only in an inactive state. During activation, information describing the mobile station's electronic serial number (ESN) is collected along with area of use information. A mobile identification number (MIN) is assigned in response to the area of use information. A page message is directed to the mobile station operating in its inactive state, but the page message references the mobile station's ESN. While inactive, the mobile station (28) detects pages directed to its ESN. A remote programming session is then performed wherein digital user-specific programming data, including the newly assigned MIN, are transferred to the mobile station (28) over a voice channel using a control channel protocol (80).
