Abstract
Techniques for use in transferring an assignment of a secure chip of a wireless device from a current subscription manager (SM) of a current mobile network operator (MNO) to a new SM of a new MNO are described. In one illustrative example, the current SM receives a request for transferring the assignment and produces transfer permission data in response. The transfer permission data includes an identifier of the secure chip, an identifier of the current SM, and a digital signature of the current SM. The current SM then sends to the secure chip a transfer permission message which includes the transfer permission data. The transfer permission data indicates a permission for the secure chip to transfer the assignment from the current SM to the new SM. Additional techniques are performed by the secure chip, and the new SM, as described.
