eSIM

TINY CHIP. BIG DEAL.

eSIMs are changing the future of connectivity for mobile operators, device makers and consumers all around the world.

WHAT IS AN eSIM

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

Developed by the GSMA, the eSIM (or embedded SIM) is a rewritable chip that is embedded directly onto a device allowing secure activation, completely over the air. eSIM enables consumers to activate mobile plans from mobile operators from anywhere, without having to physically put a SIM card in the device. This means more accessibility, less plastic and reduced cost across the whole ecosystem.

FOR THE FUTURE

Enabling an invisible revolution with eSIM

FUTURE-PROOFED IoT

DIGITAL-FIRST CONSUMERS

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.

eSIM for consumer devices

eSIM breaks down barriers to connectivity for consumers. We're helping mobile operators to accelerate their eSIM with our market-leading solution.

• Simpler device setup without the need to insert or replace a SIM card.
• Host multiple devices on a single plan, host multiple operator profiles on a single device.
• Wearable tech that can operate independently of a tethered smartphone, with their own subscriptions.
• A range of new, enhanced mobile-connected devices.

GSMA-accredited
