A system and method are disclosed in which a service provider in a first environment of a first plurality of competing, overlapping mobile networks has at least one service node. The service provider offers subscriptions based on SIM modules from at least one of a second plurality of mobile telephone operators in a second environment. The first plurality of operators has agreements for interconnect traffic with the second plurality of operators. Mobile users that are visitors in the first environment can communicate, through any appropriate network selected from the first plurality of mobile networks, which avoids the detouring of incoming calls to the visiting mobile users.
