A method and apparatus for controlling roaming in a multiple service provider environment. When a mobile station determines that it can no longer obtain acceptable service from a primary service provider, the mobile station determines whether it is operating at the periphery of the primary service provider coverage area. If it is, then the mobile station is permitted to obtain service from a secondary service provider (i.e. roam). If it is determined that the mobile station is not operating at the periphery of the primary service provider coverage area, then the mobile station is prevented from roaming for a time period which allows the mobile station to emerge from a presumed coverage hole.
