1. 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, 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, wherein the SIM card or the eSIM profile is inactive;
determining, by the equipment identity register application, that the UE having the SIM card or eSIM profile is attempting to attach to the target mobile network for a first time based on the IMEI of the UE and the SIM ID identifying the SIM card or the eSIM profile;
adding, by the equipment identity register application, an event to an event queue of the target mobile network, wherein the event indicates the IMEI of the UE and the SIM ID identifying the SIM card or the eSIM profile; and
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 indicated by the IMEI of the UE;
when the IMEI of the UE is indicated in the subscriber data:
transmitting, to the UE using a target mobile network application program interface (API), an instruction to activate the SIM card or eSIM profile at the UE;
transmitting, to the UE using the target mobile network API, SIM data to the UE to program the SIM card or the eSIM profile at the UE, wherein the SIM data associates the SIM card or the eSIM profile to the subscriber; and
permitting the UE to attach to the target mobile network after activating the SIM card or the eSIM profile and transmitting the SIM data to the UE.
