eSIM for Ireland

Data for Dublin, Galway, Kerry and the whole Wild Atlantic Way, installed before you fly. Ireland is on the Europe plan, and so is the United Kingdom: the drive north to Belfast and the Giant’s Causeway stays on one eSIM. The rain comes free of charge.

Good to know

What's included, when it starts, and how to get connected.

Included countries
The Ireland plan covers Ireland only.
Local networks
In Ireland your eSIM connects to Three and Eir — 4G/5G where the network offers it.
When validity starts
Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
Installation and activation
Install the eSIM while you still have internet — at home or on Wi-Fi. Installation does not start validity. If you already have a onesim eSIM installed, a new package is added to it — no second installation. Setup guide
Calls and texts
onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
Support and refunds
Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy

Ten days on location, from Normal People to Star Wars.

Film crews keep coming back to the island’s edges, and one loop by car strings their locations together: the capital, the Antrim coast, Achill and the Skelligs. The line below is an illustration, not a map.

The campanile in Front Square at Trinity College Dublin1

Dublin · Days 1–2

Normal People sent Connell and Marianne to Trinity College and filmed there with real students as extras. Wednesday moved its second season to Ireland in 2024 — Ashford Studios in Wicklow, Deansgrange Cemetery in Dublin — and was back in the city for the third in 2026. Have the first pint anywhere but Temple Bar.

The Dark Hedges, an avenue of old beech trees in County Antrim2

The Causeway Coast · Days 3–4

The border is easy to miss: the only sign is the switch to mph. The Dark Hedges, Game of Thrones’ King’s Road, have been closed to cars since 2017; the Giant’s Causeway is free to walk, its visitor centre is not. Unless you are Irish, British or live in Ireland, the UK expects an ETA (£20 in 2026) or a visa here too.

The sandy beach of Keem Bay on Achill Island, County Mayo3

Achill Island · Days 5–7

The Banshees of Inisherin started filming on Inis Mór and finished here in 2021: Colm’s house stood at Keem Bay, Cloughmore played JJ Devine’s pub and Purteen Harbour the shop. Achill, the largest of Ireland’s islands, has been joined to the mainland by a bridge since 1887, so no ferry is needed.

Stone beehive huts on Skellig Michael, with Little Skellig in the sea beyond4

Kerry and the Skelligs · Days 8–10

Skellig Michael played Luke Skywalker’s island in two Star Wars films. Rian Johnson’s crew could not shift the island’s puffins, so they turned them into porgs. Landings run from 12 May into September in 2026, with permitted boats only, from Portmagee and nearby harbours: 618 steps, no children under 12, and plenty of days called off by the sea.

How the plan fits this route

Ireland and the United Kingdom are both on the Europe plan, so one package covers the whole loop — Dublin, the Antrim coast and the Atlantic side — with nothing to switch at the border. Coverage is good in the towns and along the main roads, and thins on the headlands, on the islands and on the boat to the Skelligs, as it does for everyone.

Travel notes

Five corrections, delivered politely.

The sea cliffs of Sliabh Liag above the Atlantic in County Donegal
The meme

Split the G is a sport now. The two-part pour is theatre.

The game: stop your first gulp where the line between stout and head crosses the middle of the G on the glass. It has been on Urban Dictionary since 2018 and on phone screens ever since. The pour you wait for — 119.5 seconds between the two parts, says Guinness — is ‘a cod’, Irish slang for nonsense, according to an Irish Times columnist: it changes nothing about the taste. Wait anyway. It is the show.

Hot take

The Cliffs of Moher are the famous ones, not the tall ones.

Moher tops out at 214 metres and drew about 1.1 million visitors in 2022. Sliabh Liag in Donegal climbs to 601 metres straight out of the Atlantic, and Croaghaun on Achill has the highest sea cliffs in Ireland, third-highest in Europe, visible only on foot or from a boat. See Moher, by all means. Then keep driving north.

Myth

‘Craic’ is not an ancient Irish word. It is English, respelled.

The word for fun, news and good conversation began as the English and Scots ‘crack’, from the Middle English crak, loud talk. Irish borrowed it as craic in the mid-20th century, and English took it back, Irish spelling and all, in the 1970s. Knowing this will not make you friends at the bar. Asking ‘what’s the craic?’ will.

Food fight

The island has two Taytos, and neither one is the other.

Joe ‘Spud’ Murphy founded Tayto in Dublin in 1954 and is credited with the world’s first flavoured crisp: cheese and onion. Two years later a company in Tandragee, County Armagh, licensed the name and the recipes, and Tayto Northern Ireland has been a separate firm ever since, making its crisps beside a castle. Taste both before you pick a favourite.

Driving

Dublin’s M50 toll has no booths. Pay by 8 p.m. the next day.

Between junctions 6 and 7, cameras photograph every number plate, and drivers without a tag or an account must pay online, by phone or at a Payzone shop before 8 p.m. the following day; after that, penalties are added. With a hire car, ask at the desk how the toll is handled. Everywhere else the one rule to remember is simpler: keep left.

Ireland questions.

Answers about data, coverage and setup for Ireland.

Yes. Northern Ireland is part of the United Kingdom, and the United Kingdom is on the Europe plan too, so the package carries on with the same allowance. The border is open and easy to miss; close to it, the phone may hop between Irish and UK networks, and both sides are covered. The giveaway is the road signs: speed limits in km/h in the Republic, in mph in Northern Ireland.
