Press Releases

TOKYO, JAPAN, June 27, 2014 --- NTT DOCOMO, INC., a personalized mobile solutions provider for smarter living, announced today it will offer Japan's first Embedded Subscription Identity Module, or eSIM, a new type of SIM that works on mobile networks of various international operators, for M2M Devices. DOCOMO's eSIM, which is able to register phone numbers and other subscription-identity data of DOCOMO and other international operators in machine-to-machine (M2M) devices, such as connected automobiles, industrial equipment and many more, will be available to business customers from June 30.

Conventionally, connecting a M2M device to a local mobile network requires a SIM offered by the operator. DOCOMO's new eSIM, however, will enable a single embedded SIM to load subscriber identities issued by multiple mobile operators. This will simplify manufacturing and inventory-management tasks over operator-specific SIMs, a major advantage for transnational M2M enterprises and solution providers. Also, subscriber identities stored in the eSIM will be interchangeable as the user moves from country to country with their M2M device, leading to enhanced operability.

DOCOMO's eSIM will be available as a M2M solution for corporate customers using the docomo M2M Platform in Japan.

The eSIM is an emerging technology in the global M2M industry. DOCOMO, a member of GSMA, has been actively involved in the establishment of an eSIM global standard, which was officially released in December 2013. Going forward, DOCOMO is committed to offering advanced M2M services to support Japanese and international business customers.
