<p>A mobile station (10) has a memory (24) that stores an Intelligent Roaming DataBase (IRDB) that includes a Home Only Enable control bit. The HOE control bit is made to have a factory default (non-activated state) that is enabled, so that prior to activation the mobile station is permitted to camp only on the home system. A home system in this context means a system broadcasting a System Operator Code (SOC) equal to a SOC stored in the mobile station's Number Assignment Module (NAM). Subsequently allowing roaming to non-home systems (i.e., disabling the Home Only Enable control bit in the IRDB) after activation, without Over the Air Programming, can be accomplished by the mobile station automatically disabling the Home Only Enable control bit after Over the Air Activation or some other type of activation.</p> |
