The International Telecommunication Union (ITU) allocates global mobile subscriber identity (IMSI) ranges, enabling cross-border connectivity through 'global sims' that facilitate communication for IoT and M2M applications. These global sims support seamless deployment across various sectors including smart cities, healthcare, and logistics, allowing manufacturers to expand operations internationally. To apply for a shared MCC 901 and obtain global IMSI ranges, organizations must hold sector membership or associate status with ITU and submit a formal application.
