ABSTRACT:
Methods, systems and computer program products for providing roaming services to a wireless telephone roaming outside of its home service area by receiving a request for roaming service from a wireless telephone that is within a roaming network and offering a special roaming contract to the user of the wireless telephone. The request for services comprises an identify of the wireless telephone wherein the identity comprises the mobile identification number and the electronic serial number. Using the identity of the wireless telephone received in the request, the roaming network determines that the wireless telephone identity is not recorded as a record within the roaming network and is therefore roaming. The method provides offering a special roaming contract to the user and then executing the special roaming contract if the user decides to accept the offer for a special roaming contract.
