In the background of the technology looked to address the following issues: The GSM Association (GSMA) which brings together about 800 operators and 250 mobile ecosystem companies became the first to come up with the Consumer Remote SIM Provisioning initiative.
[9] The specification that covers the carrier selection aspects aims to allow consumers to choose a mobile network operator from a wide range to activate the SIM embedded in a device via a subscription.
The specification that covers the carrier selection for M2M devices is simpler since typically there is no subscriber involved (e.g. changing the operator in an electricity meter).
[12] Once validation is complete the LPA will coordinate a secure channel between the eUICC and the SM using challenge-response authentication to enter programming mode.
The LPA will request carrier profiles available for download, either by submitting the activation code provided by the user or the eSIM ID (EID) of the eUICC.
