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

This was my first e-SIM experience, and believe me, the signal is much better than the lines in Turkey. I traveled to four different cities in Indonesia and got 5G in all of them. 5 GB of internet lasted me three weeks. Thank you.

This is the best part... A fantastic app. I had no problems during my week-long vacation in Paris, France. I used it on my Android phone and the setup was very easy with the QR code. The package prices are also much more economical compared to other e-service providers. Plus, you don't easily use up your internet data unless you're watching videos.

Does a UK eSIM Work in Ireland? The Ultimate Guide to Confusing eSIM Destinations
The Double-eSIM Trap Picture this. You are planning a dream trip to Italy with a day trip to the Vatican. You search "eSIM" and see Italy and Vatican City listed as two separate options.
