  • Surrogate cellularless roaming
    Patent number: 10462303
    Abstract: Cellularless roaming avoids excess charges in private cellular network. A user swaps a subscriber identity module from a mobile device and into a surrogate cellular device. The surrogate cellular device may then use the subscriber identity module to establish wireless communication in a home location of a private cellular network. The surrogate cellular device, though, may still communicate with the mobile device using the public Internet. Whenever the surrogate cellular device receives a cellular call or data, the cellular call or data may be routed via the public Internet to the mobile device. The user may thus carry the mobile device to any country in the world and avoid roaming charges.
