GSMA-Compliant eSIM Solution

eSIM, also known as eUICC, is a new embedded SIM which supports the GSMA remote SIM provisioning specifications. For consumer and M2M devices, it allows secure storage and remote management of multiple operator profiles on cellular devices. It brings greater flexibility and reduces the cost of managing IoT deployments, as well as allowing for smaller embedded or integrated form factors.


Tap into the limitless possibilities of IoT with GSMA-compliant eSIM solution from Arm. Whether you’re an MNO or IoT service provider looking to expand your customer base; an OEM wanting to build an eUICC into a device or an enterprise planning to scale up IoT deployments, we’ve got the best solution for you.

iSIM for More Integration

iSIM extends the eSIM innovation further to bring smaller, more power efficient devices and simplify supply chain for OEMs. Instead of a separate eSIM chip, iSIM is integrated in the same system on chip (SoC) as the device’s microprocessor. This new level of integration releases space on the device, reduces the bill of materials and has the potential to reduce power consumption of the device. Importantly, device and cellular module makers will be able to simplify their supply chain by receiving iSIM silicon with in-built SIM OS directly from chipset makers.
