Electronic subscriber identity module (eSIM) transfer from inactive device

A method of updating electronic subscriber identity module (eSIM) credentials from an inactive mobile communication device to an active mobile communication device, comprising:

• receiving, at a subscription manager data preparation (SMDP+) server, identification data for eSIM credentials associated with the inactive mobile communication device, the identification data for eSIM credentials received from the active mobile communication device;
• validating, by the SMDP+ server, an integrated circuit card identifier (ICCID) of the inactive mobile communication device, an embedded universal integrated circuit card identifier (EID) of the inactive mobile communication device, a matching identifier (ID) associated with the eSIM credentials, and a confirmation code associated with a user;
• assigning the eSIM credentials to an EID of the active mobile communication device;
• and
• initiating, by the SMDP+ server, a package download to transfer the eSIM credentials to the active mobile communication device.

A first mobile communication device configured to obtain electronic subscriber identity module (eSIM) credentials from an inactive mobile communication device, the first mobile communication device comprising:

• a peer-to-peer wireless interface configured to:
• communicate with an inactive mobile communication device via a peer-to-peer wireless interface;
• and
• receive identification data for the eSIM credentials as stored in the inactive mobile communication device;
• a wireless transmitter configured to transmit the identification data for the eSIM credentials to a subscription manager data preparation (SMDP+) server;
• and
• a wireless receiver configured to receive the eSIM credentials from the SMDP+ server.
