The present invention provides a method and system for mobile communication where upon detecting a change in registration of a SIM device at a visited operator (VPMN), the SIM device's IMSI profile is switched to one of a HPMN IMSI profile or local IMSI profile of a hub operator. The hub operator is selected from a cloudSIM hub ecosystem, depending on the location of the SIM device and quality and regulatory requirements of the service associated with the SIM device. The cloudSIM hub allocates dynamic IMSI with either a partial IMSI profile or a full IMSI profile based on SIM device requirements. The full profile has security key information of HPMN or the VPMN, and the SIM device requirement can be from either a softSIM, an eSIM or a standard SIM. |
