A spare number, without the faff
A spare number for the apps you chat on. We give you a real UK mobile number that lives on your phone as an eSIM, so you can keep a separate account — or simply keep your own number to yourself.
Part of the Mindszi family
eSIM Chat is built and operated by Mindszi, who build the connectivity software behind mobile brands around the world. That’s why a focused product can issue real UK lines and have them working on your phone within minutes.
It runs on eSIM Copilot, Mindszi’s platform for launching and running eSIM products. New to eSIMs? Start with what an eSIM is or how a second number works.
What we stand for
Your everyday number stays yours
The point of a spare line is that you stop handing out the number your family, bank and doctor use. Your main number never changes.
A real number, not a workaround
It’s a real UK mobile number on a real network — so calls, texts and verification codes arrive normally. Not a virtual or disposable app number.
One phone, two lines
It installs as an eSIM beside the SIM you already have. No second handset, nothing in the post, set up in minutes.
Pick the app you chat on
Same real UK line either way — installed in minutes.
