China Mobile and NTT DOCOMO to Launch World’s First IoT Multi-vendor eSIM Solution

China Mobile and NTT DOCOMO to Launch World’s First IoT Multi-vendor eSIM Solution

26 June, 2018

— To support corporate customers’ IoT business expansions in China —


June 26, 2018— China Mobile and NTT DOCOMO, INC. (DOCOMO) announced today that on July 2 they will launch an eSIM1 solution to enable cross-vendor SIM profile switching from DOCOMO to China Mobile. 


This solution allows DOCOMO customers from Japan with IoT equipment in China to switch the mobile numbers (profiles) of their IoT equipment from DOCOMO to China Mobile even with different SIM vendors adopted by the two operators, thus eliminating the need to replace physical SIM cards.


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


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


DOCOMO has commercialized the eSIM solution since 2014 and launched a commercial service with Telefonica Brasil S.A. (Vivo) in 2015. This eSIM partnership between China Mobile and DOCOMO was initiated and implemented by China Mobile International with DOCOMO since Jun 2017. DOCOMO has also been pursuing various eSIM projects through partnerships with international mobile operators including IoT World Alliance3, SCFA4, Conexus5. Gradual expansion to Europe, Asia, Middle East, America is planned. Going forward, DOCOMO will continue to support the global expansion of customers’ IoT services leveraging its eSIM solution and global IoT solution “Globiot”.


Information about the multi-vendor eSIM solution will be exhibited at China Mobile’s booth during Mobile World Congress Shanghai 2018 from June 27 to 29.
