PRIMARY eSIM ACTIVATION FOR WIRELESS DEVICE WITH PHYSICAL SIM

A method for electronic Subscriber Identity Module (eSIM) provisioning to a wireless device, the method comprising:

• by the wireless device:
• determining whether a physical subscriber identity module (pSIM) presently installed in the wireless device is in a warm state configured to be used as a limited functionality pSIM for provisioning an eSIM to the wireless device;
• when the pSIM is in the warm state:
• downloading, via a cellular connection established via a limited functionality of the pSIM, the eSIM from a provisioning server of a mobile network operator (MNO);
• and
• installing the eSIM on an embedded universal integrated circuit card (eUICC) of the wireless device.

A wireless device comprising:

• wireless circuitry comprising one or more antennas;
• and
• one or more processors communicatively coupled to the wireless circuitry and to a memory storing instructions that, when executed by the one or more processors, cause the wireless device to provision an electronic Subscriber Identity Module (eSIM) for access to services of a mobile network operator (MNO) by at
• determining whether a physical subscriber identity module (pSIM) presently installed in the wireless device is in a warm state configured to be used as a limited functionality pSIM for provisioning an eSIM to the wireless device;
