The method includes receiving at a service node, a registration message by the subscriber to register with the visited network that has a No-Roaming Agreement (NRA) with the home network. The method further includes sending by the service node, an update message to a switching unit to update a trigger profile information at the switching unit so as to enable redirection of call control associated with the subscriber to the service node, wherein the switching unit is associated with the visited network. The method further includes facilitating completion of the subscriber's registration process in the visited network by the service node. Finally, the method includes authenticating the subscriber by the service node with the home network using one or more parameters of the subscriber's profile information.
