Embodiments are provided for registering an electronic device of a subscriber for cellular-based communications. According to certain aspects, the cellular-based communications may be facilitated by a data center while the electronic device is not easily within range of a cellular network, such as when the electronic device is traveling on an aircraft. A first, ground-based part of the registration includes creating an account for the electronic device that indicates an identification of the electronic device retrieved from a home network of the subscriber. A second, air-based part of the registration includes connecting to the electronic device via an on-board communications system and communicating with the home network to indicate that the location of the electronic device is known.
