Abstract
Disclosed is a system and method for enabling a cellular telephone subscriber located in a foreign service area to designate how calls placed to the subscriber should be handled by entering selections (such as call forwarding, caller notification) from the keyboard of his mobile telephone set. When these selections are received by a foreign service MTSO, the foreign service MTSO validates the roaming subscriber and the services that are available to the subscriber and then notifies the home MTSO how calls received at the home site should be handled. If the caller is to receive calls in the foreign service area (either forwarded calls or direct calls to the foreign service area), the foreign MTSO assigns a temporary roaming number to the subscriber for use in the foreign service area after the subscriber has been validated.
