Japan’s NTT DoCoMo has chosen Giesecke & Devrient (G&D) to provide subscription management services for new M2M devices using embedded SIMs (eSIMs).

The operator claims to be in the process of launching Japan’s first commercial eSIM service and says G&D (Munich, Germany) will provide both M2M SIMs and managed services allowing customers to download and switch between subscriptions.

eSIMs are seen as a critical enabler of global M2M services because they allow customers to change service providers without having to physically replace the SIM, which is impossible in certain types of device.

NTT DoCoMo (Tokyo, Japan) believes the G&D solution will simplify the deployment of M2M devices in a range of vertical markets, including the automotive and industrial equipment sectors.

Devices that include eSIMs should be capable of operating across multiple geographical markets, noted G&D in a statement.

The technology provider claimed its own software and services would allow SIMs to be managed “over the air”, meaning devices can be updated remotely and without the need for a site visit by technicians.

G&D also emphasized that such flexibility would not compromise the security that is so essential when managing confidential subscription data of mobile network operator partners.

“G&D is proud to be DoCoMo’s technology partner to bring this eSIM solution to market and enable more M2M devices and applications,” said Carsten Ahrens, the group senior vice president and head of telecommunication industries division at G&D. “We have leveraged our pioneering research and proven experience in secure remote management of subscription data on eSIMs to provide this cutting-edge solution, enabling MNOs to meet the demands of their M2M customers.”

G&D also claimed that its services had been shown to minimize the impact on SIM logistics and ordering processes already established by mobile network operators.
The M2M Zone serves as the catalyst to the embedded systems community to gather knowledgeable and up-to-date information. From telematics to smart grid to telehealth, the M2M Zone understands that machine-to-machine technologies stretch across multiple industries to create a dynamic M2M eco-system.
