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.

What our customers say

During my 5-day trip to Greece, my wife and I shared the "Europa special 10 GB" package. We used it extensively and without interruption in all 5 days, but only managed to use 5 GB. If I ever travel abroad again, I will definitely choose Mobimatter.

I'am very pleased. They are so helpfull. I've been using them for 5 years; their prices are reasonable and they offer a wide variety of options. They provide quick assistance via email if there's a problem. They ask for screenshots, and even if I send them in a different language, they provide support quickly. Thank you! 🥰

I used it in Italy in 2024 and in Spain in 2026, and I was very satisfied. The app has improved day by day, and I never experienced any issues. I don't know about other apps, but I highly recommend MobiMatter. I bought 15GB of internet in Spain, and even though I didn't use that much, I still have 10GB left.
