Event triggered network migration of subscribers

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:

• adding, by an equipment identity register application in the target mobile network, an event to an event queue of the target mobile network, wherein the event indicates an International Mobile Equipment Identity (IMEI) of a user equipment (UE) associated with the subscriber and a Subscriber Identity Module (SIM) identifier (ID) identifying a SIM card inserted into the UE or electronic SIM (eSIM) profile installed at 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;
• and
• transmitting, to the UE using a target mobile network application program interface (API), SIM data and an instruction to activate the SIM card or the eSIM profile, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber when the IMEI of the UE is indicated in the subscriber data.

A system comprising:

• at least one processor;
• at least one non-transitory memory;
• and
• a network event orchestration manager application, stored in the at least one non-transitory memory, which when executed by the at least one processor, causes the at least one processor to be configured to:
• process an event from an event queue by accessing subscriber data stored at a source mobile network to validate that an International Mobile Equipment Identity (IMEI) of a user equipment (UE) is indicated in subscriber data stored at the source mobile network, wherein the event indicates the combination of the UE with a SIM card inserted into the UE or electronic SIM (eSIM) profile installed at the UE, and wherein the subscriber data includes a subscriber account of a subscriber associated with the IMEI of the UE,
• transmit, to the UE using a target application program interface (API), SIM data and an instruction to activate the SIM card or eSIM profile at the UE, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber,
• determine a source service for the subscriber that is to be migrated from the source mobile network to the target mobile network,
• determine a target service provided by the target mobile network, wherein the target service matches the source service, and
• access service data associated with the source service at the source mobile network to provide the target service to the UE.
