Summary: | To virtually transfer subscriber identity module ("SIM") credentials from an active device to an inactive device in order to share carrier network access, temporary identifiers and SIM credentials are transferred using secure connections and an optional public-private key pair with encryption at the transport layer. In an example, a carrier identification ("ID") server receives a temporary identifier, such as a temporary international mobile subscriber identity ("TIMSI"), from an inactive device via a carrier network. The carrier ID server authenticates the inactive device using the TIMSI by issuing a network challenge. Next, the carrier ID server verifies with an active device associated with the inactive device that the active device distributed the TIMSI. After authenticating and verifying with both devices, the carrier ID server activates the inactive device by allowing the TIMSI to behave as virtual SIM credentials on the carrier network. |
