It has been announced by China Mobile and NTT DOCOMO (DOCOMO), that on 2nd July they launched an eSIM 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 profiles when switching between their mobile networks. The new GSMA 3.1 specifications adopted by this eSIM solution, however, allow the overwriting of eSIM information of operators who use different SIM vendors.
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.
DOCOMO commercialised the eSIM solution in 2014 and launched a commercial service with Telefonica Brasil S.A. (Vivo) in 2015. DOCOMO and China Mobile International signed an IoT Service Agreement including eSIM solution in November 2017.
DOCOMO has also been pursuing various eSIM projects through partnerships with international mobile operators including IoT World Alliance, SCFA and Conexus. Gradual expansion to Europe, Asia, Middle East and 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’.
