Will it work at Slieve League and Glenveagh?

You may get a signal at the Slieve League car park and Glenveagh visitor centre, but both drop out on the higher cliffs and deeper glens. Treat the trails themselves as offline and save your route beforehand.

Does the eSIM work in the Donegal Gaeltacht and near the border?

Yes, across the Gaeltacht towns and villages you'll have data, though rural stretches vary. Near the Northern Ireland border your phone may occasionally try to roam onto a UK network, so check it stays on an Irish one.

Good to know in County Donegal

Donegal is one of Ireland's least densely covered counties; on the Slieve League cliffs, the Fanad and Inishowen peninsulas and Glenveagh's glens, expect dead zones, so carry offline maps and tell someone your route if hiking alone.

Best time to visit County Donegal

May to September brings the mildest weather and the most reliable surf at Bundoran, with long summer evenings ideal for Slieve League and Fanad Head.

Two simple ways to buy

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

County Donegal eSIM: your local data guide.

Remote and ruggedly beautiful, County Donegal spans the towering Slieve League cliffs, Glenveagh National Park's glens, Bundoran's surf breaks and the Gaeltacht villages of the northwest. A County Donegal eSIM helps you navigate the winding Wild Atlantic Way and book surf lessons across a county where the interior and coast can lose signal fast.

One eSIM for County Donegal and all of Ireland. It's the national Ireland eSIM — from $2.15/day with unlimited data, working the same in County Donegal as it does the moment you leave it.

Across the region

Where you'll lean on data in County Donegal.

Letterkenny

The county's largest town has the strongest, most reliable coverage, making it a natural base for exploring the region.

Slieve League

Among Europe's highest sea cliffs, but wildly exposed - expect patchy signal and genuine dead spots on the higher paths.

Glenveagh National Park

Coverage is thin across the mountains, glens and Poisoned Glen, so download trail maps before you set out.

Bundoran

This surf town on the southern coast has good, steady data for checking swell and booking board hire.

The practical bit

Apps you'll want online in County Donegal

Bus Eireann— Coaches linking Letterkenny and Donegal town to Dublin and beyond.

How long to stay in County Donegal

Three to four days lets you explore County Donegal properly - Slieve League, Glenveagh, the Fanad and Inishowen peninsulas and a surf stop at Bundoran or Rossnowlagh.

How much data for County Donegal

A balanced 3-5 GB suits touring, but download offline maps generously - Donegal's remote coast and mountains mean you'll often navigate without live data, so don't count on streaming out here.

Coverage in County Donegal

Letterkenny, Bundoran and the main towns have decent 4G, but Donegal is genuinely one of Ireland's patchiest counties - Slieve League, Glenveagh and the peninsulas all have real dead zones.
