1. A method of sharing electronic subscriber identity module (eSIM) credentials between two mobile communication devices, comprising:
establishing, by a source user equipment (UE), a data connection with a subscription manager data preparation (SMDP+) server associated with eSIM credentials stored at the source UE;
notifying, by the source UE, the SMDP+ server of an intent to transfer the eSIM credentials;
subsequent to the notifying, deactivating, by the source UE, the eSIM credentials;
receiving, by the source UE, metadata describing an activation code containing identification data for the eSIM credentials; and
forwarding, by the source UE, the activation code to a destination UE, the activation code forwarded to support a download of the eSIM credentials to the destination UE from the SMDP+ server.
