Claim 8:
9. A method for migrating a subscriber from a source mobile network associated with a source mobile network operator to a target mobile network associated with a target mobile network operator, wherein the method comprises:
receiving, by an equipment identity register application in the target mobile network, when a Subscriber Identity Module (SIM) card associated with the subscriber is inserted into a user equipment (UE), an International Mobile Equipment Identity (IMEI) of the UE and an International Mobile Subscriber Identifier (IMSI) of the SIM card, wherein the SIM card is inactive;
determining, by the equipment identity register application, that a combination of the IMEI of the UE and the IMSI of the SIM card has not been previously registered with the target mobile network;
adding, by the equipment identity register application, an event to an event queue of the target mobile network when the UE combination of the IMEI of the UE and the IMSI of the SIM card has not been previously registered with the target mobile network, wherein the event comprises the IMEI of the UE;
processing, by a network event orchestration manager application in the target mobile network, the event by accessing subscriber data stored at the source mobile network to validate that the IMEI of the UE is indicated in the subscriber data stored at the source mobile network, wherein the subscriber data includes a subscriber account associated with the IMEI of the UE;
migrating, by the network event orchestration manager application, the subscriber data at the source mobile network to the target mobile network by authorizing the target mobile network to access the subscriber data stored at the source mobile network to provide network services to the subscriber, without relocating the subscriber data from the source mobile network to the target mobile network; and
transmitting, to the UE using a target mobile network application program interface (API), SIM data and an instruction to activate the SIM card, wherein the SIM data associates the SIM card to the subscriber when the IMEI of the UE is indicated in the subscriber data.
