eSIM technology

The GSMA defines different eSIM architectures for machine to machine (M2M) and consumer device use cases. The Eseye eSIM solution uses the M2M eSIM architecture.

The GSMA introduced the embedded SIM Remote Provisioning Architecture (eSIM) to remove the need to physically swap SIM cards when changing mobile networks and enable SIM provisioning over-the-air. This is especially important for IoT devices, which may be located in remote locations and may have embedded SIMs that cannot be swapped.

eSIM technology requires devices with eUICC SIMs that support the use of operator profiles, and remote SIM provisioning systems in the network to perform the updates. Both the eUICC SIMs and remote provisioning systems must achieve GSMA certification and operator-specific certification before they can be used on a live network. This ensures security and interoperability between operators.

Eseye's eSIM solution

Eseye has agreements in place with multiple operators which enables Eseye to download profiles from operators with the best connectivity or services for the connected IoT device. The Connectivity Management Platform can use predetermined rules to trigger the remote SIM provisioning systems to download and enable different profiles depending on the regional requirements. The available operators and services for an IoT device depend on the package assigned to the device.

For IoT devices that include an Eseye Hera router (EU/USA/RoW model only), there is an embedded eUICC as well as a physical SIM card located in the Hera hardware.
