Mobile data in Ireland: Dublin, the west coast and the border

Ireland is in the EU, so an EU plan works at home prices. The catch is thirty kilometres wide: Northern Ireland is part of the United Kingdom, which left the EU roaming rules, and the border is invisible from the car.

Is roaming free in Ireland?

  • Plans from the EU and the EEA: yes, roam like at home applies, within your operator’s fair use limit.
  • UK plans: it depends on your operator since Brexit.
  • Plans from outside Europe: usually international roaming or a daily pass.

The EU roaming calculator works out how many gigabytes that is for your plan.

Will it work on my phone?

On iPhone: Settings → General → About, and scroll to EID. If there is an EID, your phone takes eSIMs. Every iPhone from the XS (2018) onwards does.

On Android: Settings → About phone → Status, and look for EID. If there is an EID, your phone takes eSIMs. Most Galaxy S20, Pixel 3 and later do.

It also has to be carrier-unlocked. If you bought it outright or your contract is over, it almost certainly is.

Dublin to Belfast: where the rule stops

Northern Ireland is in the UK, so once you cross, the EU rule no longer applies and your operator charges whatever its tariff says. There is no checkpoint to remind you. Worse, within a few kilometres of the border on either side the phone can attach to a network from the other jurisdiction while you are still where you started.

If you plan to cross, check what your tariff charges for the UK, or pick the network by hand near the border. The UK roaming guide covers the British side.

Which eSIM works in Ireland?

An Ireland eSIM runs on the local networks, Eir (5G). Data only: your number stays on your usual SIM. Note that a plan for the Republic does not cover Northern Ireland unless it lists the UK.

Coverage: Dublin, the Wild Atlantic Way and the islands

Dublin, Cork and Galway have strong coverage. Along the Wild Atlantic Way, in Connemara, Donegal and on the smaller islands it varies a lot with the terrain, and on some stretches it goes altogether. Download maps and ferry times before you drive west.

How much data for a trip to Ireland?

  • 3 GB: a long weekend in Dublin.
  • 5 GB: a week driving with maps and photos.
  • 10 GB: two weeks, or a road trip with video calls.
  • 20 GB: a month, or sharing data with a laptop.

The data calculator gives an estimate in five questions.

Prices for Ireland

Ireland data eSIMs: 3 GB for 4,49 €, 5 GB for 7,29 €, 10 GB for 11,99 € and 20 GB for 20,29 €. The plan starts on the first connection in Ireland.

Questions
Does my Irish or EU plan work in Northern Ireland?

Not under the EU rule: Northern Ireland is in the UK, which left it with Brexit. Your operator decides what it charges there, so check before you cross.

Does an Ireland eSIM cover Belfast?

Only if the plan lists the United Kingdom. A Republic-only plan stops at the border.

Is there coverage on the Wild Atlantic Way?

It varies with the terrain and disappears on some stretches, on every network. Download offline maps before driving west.

Do I need ID for a data eSIM?

No. A data eSIM bought online needs only an email address.

Get your eSIM before you fly: the QR arrives by email in minutes and the plan only starts when you connect at your destination.

A person, not a call centre

Snoozim is run from Barcelona by Ibai Guirado Vera. It exists because paying for roaming by the day on a short trip made no sense. If something goes wrong with your eSIM you write, and the same person who built this answers you, within 24 hours.
