Abstract: Embodiments described herein relate to mechanisms for error recovery during transfer of cellular service credentials between two mobile wireless devices. Transfer of credentials includes communication between a source device, a target device, and/or one more network-based servers. Authentication can be based on one or more tokens obtained by the source device and provided to the target device. Error recovery can include using redirection to different servers, providing alternative information for authentication, and storage and subsequent retrieval of information to restart or complete a credential transfer process.

Abstract: In some embodiments, an electronic device presents settings user interfaces associated with cellular identifiers. In some embodiments, a first electronic device accesses a first cellular identifier regardless of the first electronic device's connection to a second electronic device and accesses a second cellular identifier when the first electronic device is connected to the second electronic device. In some embodiments, an electronic device presents visual indications of cellular identifiers in relation to communication functions. In some embodiments, an electronic device presents visual indications of the status of cellular identifiers active on the electronic device. In some embodiments, an electronic device presents alerts associated with one or more cellular identifiers that have been removed from the electronic device.
