eUICC capable SIMs, eSIMs and iSIMs

One SIM for all destinations

Automatic switching to optimal network for roaming and static devices

Embedded Universal Integrated Circuit Card (eUICC) is a software stack which facilitates remote provisioning of mobile operators over-the-air, enabling a device to switch mobile network without having to change the SIM. More than that, however, it is storage capacity that can be used to add value to your IoT project.

eSIM can refer to an ’embedded SIM’, consisting of a chip directly embedded in the device rather than using a SIM card.

It can also mean ‘enhanced SIM’, referring to the expanded hardware, firmware and SIM management functionality provided by eUICC technology.

The integrated SIM (iSIM) is the next step in the evolution of the SIM card.
The iSIM is a Tamper-Resistant Element (TRE) integral to a System on a Chip (SoC). This means a vacuum-sealed chip is soldered directly onto a processor, integrating SIM functionalities as part of the device’s existing processing hardware. This leads to a smaller, more power efficient and secure solution which seamlessly integrates with all generations of mobile networks.
