Up until now, different mobile operators were required to use the same vendor to overwrite eSIM profiles when switching between their mobile networks. The new GSMA 3.12specifications adopted by this eSIM solution, however, allow the overwriting of eSIM information of operators who use different SIM vendors, making this the worlds first multi-vendor eSIM system.

NTT DOCOMO, Japans leading mobile operator with over 76 million subscriptions, is one of the worlds foremost contributors to 3G, 4G and 5G mobile network technologies. Beyond core communications services, DOCOMO is challenging new frontiers in collaboration with a growing number of entities (+d partners), creating exciting and convenient value-added services that change the way people live and work. Under a medium-term plan toward 2020 and beyond, DOCOMO is pioneering a leading-edge 5G network to facilitate innovative services that will amaze and inspire customers beyond their expectations. DOCOMO is listed on the Tokyo Stock Exchange (9437).

By doing away with the need to replace physical SIM cards, the new system will enable smooth switching between mobile networks when companies send connected automobiles or construction, agriculture or production machinery from Japan for use in China.
