摘要： Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

摘要： A device, system, and method persists network registration rejection causes. The method is performed at a device connected to a network and comprising a temporary memory and a persistent memory, the device using the data stored in the temporary memory when performing network registration operations. When a power cycle is detected, the method includes determining whether there is persistent data in the persistent memory for a first attempt to register with the network prior to the power cycle, the persistent data including a rejection cause for the first attempt. When there is the persistent data in the persistent memory, the method includes determining whether the persistent data is valid for a second attempt to register with the network after the power cycle. When the persistent data is valid, the method includes generating and storing cause data based on the persistent data in the temporary memory prior to the second attempt.

摘要： This Application sets forth techniques for routing emergency (SMS) messages under limited-service scenarios. One technique can be implemented by a network entity associated with a mobile network operator (MNO), and include the steps of (1) receiving an SMS message from a wireless device, and (2) in response to determining that (i) the wireless device is communicatively coupled to the MNO under a limited-service connection due to being unaffiliated with the MNO, and (ii) a destination address of the SMS message corresponds to an emergency service: (a) identifying at least one emergency service provider that corresponds to the MNO, and (b) providing at least a portion of the SMS message to the emergency service provider.
