AT&T has teamed up with Giesecke+Devrient Mobile Security (G+D) and Altair Semiconductor to integrate a SIM into the modem chipset for deployment across licensed Low-Power Wide-Area cellular networks.

Right now, manufacturers buy Subscriber Identity Modules (SIM) cards for IoT devices. The SIMs securely identify and authenticate the subscriber for the mobile network -- just like for your smartphone.

With the integrated SIM, this model changes. 

An integrated SIM embeds SIM functionality into the chipset, processor and other module components. This all-in-one approach is designed to enable modules to power smaller, less costly and more energy-efficient IoT devices, but still with the same carrier-grade security of a physical SIM.

The integrated SIM is a departure from the present model where manufacturers buy separate SIM cards for IoT devices.

AT&T says that it believes that traditional SIMs will still be in use for years to come, but it expects the integrated SIM will make it easier for large-scale global deployments of low-cost asset trackers, smart sensors and more over LPWA networks designed for the IoT.

The solution integrates G+D's SIM solution with Altair's ALT1250 chipset and AT&T's U.S. LTE-M network. 

In a statement, AT&T said it expected integrated SIM to be commercially available by the first half of 2019.

"This advance represents the next generation of secure SIM solutions for the IoT," said Cameron Coursey, vice president, IoT Solutions, AT&T. "We expect the design to enable wide acceptance by other operators and to become mainstream as the IoT takes off globally."

"The combination of G+D's Secure SIM Operating System, coupled with AT&T's global leadership in the IoT space and Altair's ALT1250 chip will pave the way for the accelerated deployment of IoT devices." said Bernd Mueller, Head of the Connectivity & Device Solutions Division at G+D Mobile Security.

"Altair's ALT1250 is already the most integrated and advanced chipset supporting LTE-M and NB-IoT," added Ilan Reingold, VP of Business Development and Marketing for Altair. "With this announcement, the ALT1250 will include an integrated SIM secured by a hardware element. This will increase the value to our customers and partners by enabling easier and more flexible LTE connectivity without compromising on security."
