G+D Mobile Security Runs Singapore eSIM Trial

IMDA, Singapore’s ICT regulatory Agency authority, partners with G+D Mobile Security and PUB, Singapore’s National Water Agency, to trial a remote connectivity management solution based on eSIM Management Standard.

G+D Mobile Security have undertaken a three-month Embedded SIM (eSIM) trial in Singapore, in partnership with PUB, Singapore‘s national water agency. The testing is another boost to the country’s ambitious “Smart Nation“ project, which facilitates innovation in digital technology.

G+D Mobile Security is spearheading the international development of eSIM technology and was selected by the Info-communications Media Development Authority of Singapore (IMDA) as lead contractor to test an open over-the-air (OTA) subscription management (SM) standard for eSIMs, which enables utility sensors to switch between mobile network operator (MNO) networks, without having to physically replace their SIM cards.

Testing including all MNOs

Current technology requires every SIM card to be tied to a mobile network, and any change requires the card to be replaced. This presents a challenge to industry players, such as PUB, looking to deploy sensors or other machine to machine (M2M) devices via existing mobile networks. In the trials, which began in November 2016, we provided IMDA and PUB with a SIM card management system, which allows for a secure and reliable solution.

MNOs participate

M1, Singtel and Starhub

G+D Mobile Security set up IMDA with the test bed for remote provisioning of eSIM to Internet of Things (IoT) devices. The testing was delivered over a fully functional trial network, using AirOn, together with PUB’s M2M utility sensors, which sends data to PUB’s data centre and operations. It also conducted OTA switches among participating MNOs that include the three main MNOs – M1, Singtel and Starhub – in Singapore. Regulation and standards for eSIM are essential for Singapore’s “Smart Nation“ preparation and continued involvement with the Internet of Things (IoT). Dr. Yaacob Ibrahim, Minister of Information and Communication, says: “Developing open and interoperable standards is the crucial next step in unlocking the potential of IoT.” Aileen Chia, Assistant Chief Executive and Director-General (Telecoms and Post), IMDA, said, “The trial will explore the viability of using eSIMs to enable always-on, machine-to-machine communications without the hassle of having to physically replace SIM cards when switching operators.”

Benefits for MNOs

G+D Mobile Security’s trial will provide valuable insight for IMDA and PUB into the technical challenges and capabilities of the eSIM technology, including downloading operational subscription profiles, activating selected subscriptions, and removing subscriptions from SIM cards, as well as providing opportunities for participating MNOs to understand the requirements and challenges in providing agile connectivity in the IoT world.
