Abstract
Some embodiments relate to methods for provisioning a secondary wireless device with an eSIM for wireless communication and activating multi-SIM functionality between the secondary wireless device and a primary wireless device having a subscribed SIM. The primary wireless device may act as a proxy in obtaining the eSIM for the secondary wireless device. The primary wireless device may then provide, to the cellular network, identifiers of the SIMs of the primary and secondary wireless devices. The primary wireless device may then request initiation of multi-SIM functionality for the two SIMs, and receive an indication that the multi-SIM functionality has been initiated. As an example, the multi-SIM functionality may be implemented by mapping the SIM of the primary wireless device and the SIM of the secondary wireless device (e.g., the provisioned eSIM) to the same Mobile Directory Number (MDN).
