Each plan connects to the networks listed on its page, so you choose your carrier before you buy. Coverage varies by area: a listed network does not guarantee signal everywhere.
Frequently Asked Questions
Does a Europe eSIM work in the UK?
Only if the plan lists the UK. Since Brexit the UK is outside EU roaming rules, so it is not automatically part of every Europe plan. Many Europe plans include it and some don't; the country list on the plan page shows which. UK plans cover England, Scotland, Wales and Northern Ireland.

Does a UK eSIM work in Ireland?
Not always. The Republic of Ireland is a separate country with its own networks, so a UK-only plan may not work there. If you are visiting both, choose a plan whose country list includes the UK and Ireland; many UK and Europe plans do.

Can I get a UK eSIM online before I arrive?
Yes. You can buy a UK eSIM online from anywhere and install it from a QR code or in the MobiMatter app; you don't need a UK address. Install it at home over Wi-Fi and turn it on when you land.

MobiMatters came highly recommended in family-oriented travel groups on social networks, when I was researching on travel eSIMs for Iceland. The first package I started with was a US + Europe - it was easy to activate before leaving home (and verifying), and then continue on landing in Reykjavik. Unthinkable speeds (given we are used to Verizon and TMobile in the US) - over 400 Mbps on the Fast app! Unlimited tethering options allowed me to use across my MacBook and phone, as well as share across the family with the kids on iPads and phones. Navigation on Google and Waze was aa breeze with the constant high speed data connectivity. Our plans did not support phones (we knew this) but with WhatsApp and FaceTime allowing audio and video calls we never felt the need for basic phone service. Customer service on email was responsive and helpful when I wanted to understand how top-ups work. Highly recommend MobiMatters - I’m on my third top-up as we speak!

nice app. I used it during my travel in Spain last year and the internet speed was always good. I didn't have any issues. I now bought a package that covers both Portugal and Spain, as I am going there tomorrow.

In Turkey and Georgia in the summer of 2025, I used the app, and everything worked perfectly! The prices are cheaper than buying a SIM card at the airport.
