Not just a new SIM, an entirely new way to connect

Developed by the GSMA and already widely accepted by the telecoms market, eSIM is the new standard in SIM card technology. A rewritable chip, built directly onto the device, the eSIM brings wide ranging benefits to consumers, enterprises and IoT solutions.

Wearables at scale

eSIM allows device makers to create smaller and lighter devices. This will be a crucial edge as the popularity of wearable tech grows.

eSIM for IoT

We have developed the eSIM in accordance with GSMA standards to support the mass deployment of IoT devices.

  • Load operator profiles to multiple devices remotely, over the mobile network or using Wi-Fi.
  • Swap profiles without removing the SIM. Store multiple profiles on a single device.
  • Flexibility of SIM types accounts for every possible use case and often takes up much less space than traditional SIMs.
  • Roaming and moving devices can now automatically navigate between network providers.
  • Enable IoT deployments to get updated by pushing profile changes to the devices from a unified control platform.
