NTT DOCOMO has inked an agreement with Telefonica Brasil (Vivo) to launch an embedded subscription identity module, or eSIM, targeting Japanese multi-national firms in the country. The eSIM will enable machine-to-machine (M2M) devices to work on its Vivo network for enterprises that use the Docomo M2M Platform.
According to DOCOMO, the eSIM solution enables M2M devices to use a single embedded SIM with a phone number which can be changed over-the-air to certain mobile operators, allowing companies to remotely manage connectivity with mobile operators without having to replace the SIM cards in their devices.
Permanent use of international roaming is forbidden in Brazil, so connected automobiles, construction machinery, etc. exported from Japan to Brazil have had to switch to SIMs of local operators. DOCOMO's eSIM now will make it easier for Japanese exporters to use the Vivo network in Brazil without switching SIMs.
DOCOMO's eSIM is based on specifications established in December 2013 by the GSM Association (GSMA), the world's leading association for mobile operators. DOCOMO has started offering eSIM as an M2M solution for corporate customers using the Docomo M2M platform in Japan from June 2014.
