Discover eSIM

Meet the next generation of SIM technology and discover a new way to connect. Introducing eSIMs: they work like a regular SIM, with a whole host of added benefits.

What’s an eSIM?

An eSIM is a virtual SIM that’s been built into devices like smartphones, tablets and smartwatches. As eSIMs are already pre-installed in your mobile device, it lets you activate your mobile data plan without the need to insert a physical SIM.

How do eSIMs work?

eSIMs allow you to connect to your chosen mobile network, much like a regular SIM, with a few key differences. Instead of inserting a physical SIM card, your provider will give you a QR code which you can scan to activate your eSIM. Once activated, it will work in the same way as a traditional SIM, allowing you to browse the internet or take calls via your provider’s network. Unlike standard SIMs, eSIMs also give you the freedom to have more than one number and use multiple providers.

The benefits of eSIM technology

Getting started is faster

No need to wait for a SIM card to arrive, you can set your new phone up in seconds with an eSIM. It’s win-win.

Dual SIM functionality

With room for a physical SIM card, you can have 2 numbers on 1 phone. Perfect for business and travel use.

eSIMs are greener

No physical SIM card means no plastic, plus there’s no need for any postage and packaging.
