We are the UK's first eSIM-only network, we think physical (and environmentally unfriendly) SIMs are a thing of the past and we're trying to get ahead of the curve.

An eSIM, or "Embedded Subscriber Identity Module" if you want to sound clever, is a digital SIM card.

An eSIM can be downloaded to a device over Wi-Fi or Mobile Connection. It allows users to switch between carriers and plans without swapping the physical SIM card.

Basically does what you could with a regular SIM without the faff of prodding your phone with that weird needle thing to put the SIM in.
