  • Mechanism to activate and manage a standalone device for cellular service
    Patent number: 11770695
    Abstract: Some embodiments relate to methods and systems for initiating and transferring cellular subscription service using associated cellular communication devices. Cellular service may be initiated for a first cellular communication device via a second cellular communication device. The first cellular communication device may be provisioned to operate in an independent mode. In other scenarios, cellular service may be transferred from the first cellular communication device operating in independent mode to a third cellular communication device, which may be provisioned to operate in independent mode.
    Type: Grant

  • Cellular service account transfer for accessory wireless devices
    Patent number: 11463883
    Abstract: This Application describes efficient cellular service transfer mechanisms to move cellular services that are based on cellular service credentials, e.g., eSIMs, between accessory wireless devices under various scenarios, including in some embodiments transfer of multiple eSIMs. The first and second accessory wireless devices and the primary wireless device are associated with a common user account. Transfer of credentials for cellular service access can occur between two accessory wireless devices via the primary wireless device, where the primary wireless device and the accessory wireless devices interact with applicable network-based servers.
