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.

I love using it. The internet is a lifesaver for all of us everywhere, but it's especially necessary abroad, and having a reliable connection is fantastic. Even during my overseas vacations when I changed countries, I never experienced any internet disconnections or delays; the connection was excellent.
