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’ve been travelling around SE Asia for the last 7 months, covering 6 different countries, and this app has been amazing throughout when needing to change eSIM. Very easy set-up when buying one and if you in fact are having some troubles, contacting the support team and talking through email takes no time at all. I was having some difficulty with an eSIM in Vietnam since my phone was not finding a signal no matter what I did - their support team helped me and guided me on different ways to fix it. Thank you!!

Must have esim app in your phone!!!! Cheaper packages, friendly-user and the best customer service Ive ever encountered. Any queries or problem you have, they assist you until reaching a solution.

I used it smoothly and quickly in the Netherlands, Belgium, Germany, Spain, and Bulgaria. Sparks connects to the most suitable network for your location at that moment, allowing for convenient use. Depending on your travel plans, annual options are very advantageous because it consumes very little internet data there, unlike in Türkiye.

Awesome service. I have traveled back-and-forth between the United States and the Philippines and this app has not let me down. I strongly suggest that you check your data roaming option so this way you don’t mess up what you need to do.
