A mobile station (68) is provided with intelligent roaming capabilities. The mobile station, which may be implemented as a mobile, cellular, or PCS telephone unit, includes a System Access List (SAL) that is stored in a memory (67) of the mobile station (68). The SAL may be programmed into the mobile station through a physical interface (such as a computer interface) or by using an over-the-air programming function. When the mobile station (68) is initialized, the mobile station first scans the bands of its home system (54). A secondary band may also be provided for scanning, if the mobile station is unable to locate a control channel on its home band. If the mobile station is not located within its home system, the SAL is searched to determine whether the current system is a preferred system (58). The SAL may include information on the blocks of channels to scan in the preferred bands.
