The present invention presents a system and method for attempting to register a subscriber to a Home Public Mobile Network (HPMN), wherein the subscriber is in a region having multiple overlapping wireless cellular networks. The invention detects potential registration of the subscriber with a Neighboring visited Public Mobile Network (NPMN), although the HPMN may be present in the region, in response to a registration request from the NPMN and attempts a pre-defined number of rejections upon successful detection. |
