Abstract: Systems and methods for facilitating transfer of an eSIM subscription from a source device to a target device. In one embodiment, a source device includes a transceiver and a processor system. The processor system includes an eUICC configured to store an eSIM associated with an eSIM subscription. The processor system is configured to transmit, via the transceiver and to an eSIM subscription manager server, a request for an eSIM subscription transfer activation code; receive, via the transceiver and at least partly in response to the request, a server nonce; generate a signed payload using the server nonce and source device information; transmit, via the transceiver and to the eSIM subscription manager server, the signed payload; receive, via the transceiver and in response to transmitting the signed payload, the eSIM subscription transfer activation code; and provide the eSIM subscription transfer activation code to the target device or a user thereof.
