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.

Purchased eSIM in Australia and set it up in Azerbaijan. Having never used an eSIM before, I had a few ‘user issues’. These were sorted out very quickly via email and me sending a screen shot of my ‘attempted’ setup. Technician got back to me in very short order with some simple instructions and now all good. Great efficient service.

Used this app for mobile data while in Malaysia for a few days last week. I rate it 10/10 for ease of use, affordability and for effectiveness too. After 5 days of regular usage, I still have 8GB left out of 10GB

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!
