Mobile phone peer-to-peer electronic subscriber identity module (eSIM) transfer

A method of sharing electronic subscriber identity module (eSIM) credentials between two mobile communication devices, comprising:

• establishing a peer-to-peer wireless communication link between a first mobile communication device and a second mobile communication device;
• presenting a user interface on the second device by an eSIM sharing application executing on the second device, where the user interface prompts for input of an eSIM transfer user code;
• receiving the eSIM transfer user code by the eSIM sharing application from the user interface;
• receiving eSIM credentials from the first device via the peer-to-peer wireless communication link by the eSIM sharing application;
• storing the eSIM credentials in an eSIM of the second device;
• receiving a disabled-transferred message from the first device via the peer-to-peer wireless communication link by the eSIM sharing application;
• changing a state of the eSIM of the second device by the eSIM sharing application to a disabled state;
• prompting the user by the user interface to select the second device for transfer of the eSIM credentials and to use the second device for cellular wireless communication;
• receiving an eSIM transfer input by the eSIM sharing application from the user interface;
• and
• changing the state of the eSIM of the second device by the eSIM sharing application to an enabled state, whereby the second device is enabled to communicate on a cellular wireless communication network based on authentication using the eSIM credentials received from the first device.

A method of sharing electronic subscriber identity module (eSIM) credentials between two mobile communication devices, comprising:

• establishing a peer-to-peer wireless communication link from a first mobile communication device to a second mobile communication device by the first device;
• changing a state of an eSIM of the first device by an eSIM sharing application executing on the first device to a transfer-in-progress state;
• transmitting eSIM credentials to the second device via the peer-to-peer wireless communication link by the eSIM sharing application, where the eSIM sharing application reads the eSIM credentials from the eSIM of the first device;
• deleting eSIM credentials from the eSIM of the first device by the eSIM sharing application;
• and
• transmitting an eSIM deleted message to the second device via the peer-to-peer wireless communication link by the eSIM sharing application, whereby the second device is enabled to communicate on a cellular wireless communication network based on authentication using the eSIM credentials transmitted by the first device.
