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 an Ireland eSIM work in Northern Ireland?
Only if the plan lists the UK. Belfast and the rest of Northern Ireland are part of the UK, with UK networks, and since Brexit the UK is outside EU roaming rules. For a day trip from Dublin to Belfast or the Giant's Causeway, choose a plan whose country list includes both Ireland and the United Kingdom.

For most tourists and business travellers, yes, if your phone supports eSIM. Dublin plans start at $3.49 for 2 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Dublin at no extra cost, you may not need one.

- Instagram Reels, TikTok: 0.3–1 GB

Do Dublin eSIMs support 5G and hotspot?
5G is available on 30 plans for Dublin, where the local network has 5G coverage; the others use 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Dublin eSIM come with a phone number?
Most travel eSIMs, including most Dublin plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Dublin eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except models sold in mainland China.

It's truly excellent; you can get 24/7 support when you encounter a problem. It's the best e-SIM app.

I tested the speed. It connected even faster than the internet I use at home in Turkey. There's no need to unnecessarily enrich service providers. You can use it abroad with peace of mind.

I needed an eSIM for EU and non-EU counties for the same trip. They had one package at a great price that worked great in all location. The app was great as I was able to check my data balance, in real time, quickly and easily during my trip. Would definitely use MobiMatters again. Downloading the eSIM was quick and easy too. In addition, when I reached out to Customer Support on a minor account issue, they were very responsive and addressed my issue quickly and effectively.

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.

I didn't experience any problems in Europe; it works quite well, and it's also more affordable compared to other apps.
