NTT DOCOMO is launching 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. Conventionally, a unique SIM is required for each operator.
The eSIM 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.
DOCOMO said it has been actively involved in the establishment of an eSIM global standard, which was officially released in December 2013.
