Abstract: 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.

Abstract: A method, non-transitory computer readable medium and data optimizing computing device for optimizing data for transmission obtaining data set for transmission. One or more configuration rules associated with the obtained data set are obtained. The obtained data set is optimized based on the obtained one or more configuration rules for transmission. A client code and a server code associated with the optimized data set are generated. At least one of the generated client code is transmitted to a client computing device or the server code is transmitted to a server computing device.
