View all 59 plans for Ireland · from $0.38Quick answer: The best eSIM for Ireland in 2026 is a prepaid data plan on Eir. esimbloom lists 59 plans (14 Ireland-only, 45 multi-country) from $0.38 for 500MB over 1 day; the best value for a month is 20GB for 31 days at $9.67 ($0.48/GB). Install by QR before you fly; it activates on first connection in Ireland.
Ireland is an easy country to connect in and an expensive one to roam in from outside the EU: US and Canadian carriers charge daily passes, and post-Brexit many UK plans charge for Irish roaming too. A prepaid Ireland eSIM on Eir — Ireland's largest network — replaces all of that with a one-time plan that is working before you leave Dublin Airport's arrivals hall.
esimbloom's Ireland-only plans run on Eir and cover Dublin, Cork, Galway, the Wild Atlantic Way and the Ring of Kerry. Two things make Ireland special: Northern Ireland is on UK networks, so cross-border trips need the Ireland & UK plans below, and every Europe plan in the catalog includes Ireland if you are touring further.

Ireland-specific plans in the catalog run on Eir (14 plans). A further 45 multi-country plans also cover Ireland — useful when the trip crosses borders, and shown in the table above with their country count. Each plan's network is stated on the plans page before checkout.
| Route | Cheapest plan | Validity | Price (USD) | Countries | |
|---|---|---|---|---|---|
| Ireland & UK on one eSIM Covers the Republic and Northern Ireland, plus Scotland, England and Wales — the plan to pick for any cross-border itinerary. | 1GB · Three | 7 days | $0.74 | 35 | Get plan → |
| Ireland & Europe on one eSIM Ireland plus mainland Europe on one plan for longer tours. | 1GB · Three | 30 days | $1.80 | 34 | Get plan → |
Yes. Ireland's networks all support eSIM, and a prepaid travel eSIM is installed from a QR code in Settings › Cellular › Add eSIM — no shop visit, no passport registration and no plastic. The plan is data-only, activates on the first connection to an Irish network and runs for its validity period from then.
Any carrier-unlocked, eSIM-capable phone works: iPhone XS, XR and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and most flagships since 2019.
Northern Ireland is part of the UK, and its mobile networks are UK networks. An Ireland-only plan on Eir may not connect in Belfast or on the Causeway Coast. If your trip crosses the border — Dublin to the Giant's Causeway is a classic day trip — pick an Ireland & UK plan, which lists both IE and GB in its coverage and swaps networks automatically at the border.
The reverse also applies: a UK-only plan does not cover the Republic. The combinations below show the cheapest plan that covers both.
For an Ireland-only trip the Eir plans are the best value per gigabyte. If Ireland is one stop on a wider European trip, every Europe plan in the catalog lists Ireland — the 30-, 31-, 35- and 41-area plans all include it — so one eSIM covers Dublin, then Paris, Rome and Lisbon without changing anything.
We do not quote other providers' prices on this page because they change without notice; compare on the same four points and the answer is usually clear.
esimbloom's Ireland-only plans run on Eir, Ireland's largest network by coverage. Ireland & UK and Europe plans roam onto partner networks in each country and select the strongest signal automatically.
An Ireland-only plan may not — Northern Ireland uses UK networks. Choose an Ireland & UK plan (coverage lists IE and GB) if your trip crosses the border to Belfast or the Causeway Coast.
Check your plan: after Brexit many UK operators charge for roaming in the Republic of Ireland or cap it. An Ireland & UK eSIM costs a few dollars and removes the question.
Yes — iPhone XS, XR and later, provided the phone is carrier-unlocked. Scan the QR code from your email under Settings › Cellular › Add eSIM.
Yes — the plans are ordinary mobile data, so personal hotspot and tethering work. Tethering a laptop uses data fastest, so choose a larger bundle for remote work.
esimbloom Ireland plans start from $0.38 for 500MB over 1 day, with 59 plans up to 100GB. There are no roaming fees and no contracts — you pay once for the plan you pick.
Not at the moment. The largest Ireland plan in the catalog is 100GB for 180 days at $82.00 ($0.82/GB) with full-speed data and hotspot — for most travellers that beats a throttled 'unlimited' plan.
Install it at home on Wi-Fi as soon as the QR code arrives; validity only starts when the eSIM first connects to a network in Ireland. Keep the line switched off until you land, then enable it and turn on data roaming for that line only.
