Gemalto is helping simplify and secure IoT connectivity for AT&T customers by integrating its embedded SIM (eSIM) inside the Cinterion LTE-M IoT module. 

The new solution streamlines development for OEMs and reduces the cost and complexity of IoT deployment by eliminating the need for SIM card integration after manufacturing. In addition, the eSIM helps maintain the strongest security levels with continuous security updates for the long life of IoT solutions. Samples of the new module are available with volume shipping to follow shortly.

Combining IoT efficiency with design simplicity and deployment ease

With an AT&T eSIM integrated in the Cinterion EMS31 LTE-M module, customers will take advantage of the power and bandwidth efficiency of Low Power Wide Area Networks (LPWAN) without having to buy and install SIM cards. The tiny eSIM is more than 90% smaller than traditional SIM cards making it ideal for size-constrained devices such as wearables and trackers that often need extra space for a larger battery. With fewer components to integrate, the all in one eSIM IoT module saves development effort and speeds time to market. In addition, achieving scalability is easier and the Total Bill of Materials (BOM) is reduced.

Strengthened IoT security designed in from the beginning

Integrating the SIM deeply into the module during manufacturing helps durability making it more resistant to heat and vibration while improving tamper resistance. It also strengthens security by enabling easy updates that protect devices from evolving cyber security threats. Optional embedded Secure Element (eSE) functionality can be added, providing an additional layer of security to store data in a highly secure vault and only share with authorized applications and people.

"We're pleased to work with Gemalto to make the Cinterion LTE-M module available on our network and to simplify connectivity provisioning while retaining and even improving the strongest security levels," said Cameron Coursey, vice president, Internet of Things Solutions, AT&T. "The Cinterion LTE-M IoT module with native AT&T eSIM will expand Low Power Wide Area cellular connectivity and help enable a host of new IoT use cases requiring highly integrated designs."

"The increasing adoption of eSIM technology marks a significant transformation in wireless technology that is driving innovation and improved security across the whole lifecycle of devices, said Andreas Haegele, SVP IoT Products, Gemalto. "The Cinterion LTE-M Module with embedded SIM technology benefits mobile operators and OEMs alike with enhanced flexibility and seamless connectivity for the IoT."
