Ireland eSIM
Plans from US$1.05 · instant delivery · activates when you land
An eSIM for Ireland from SimKit costs US$1.05–US$40.70 (from 1 GB / 7 days up to 50 GB / 180 days). Plans run on Eir with 5G where available. You install it with a tap, usually under two minutes, with no physical SIM to swap, and can top up if you run low.
Ireland has three mobile networks: Three, Vodafone and eir. An eSIM connects to them exactly like a local SIM would, so coverage is strong across Dublin, Cork, Galway and Limerick, along the motorway network, and down most of the Wild Atlantic Way. 5G reaches the cities and larger towns; rural Connemara, Donegal and the Beara Peninsula fall back to 4G, and a few mountain and coastal pockets have no signal on any network.
One thing to check before you buy: an Ireland plan covers the Republic of Ireland. Northern Ireland, meaning Belfast, Derry and the Causeway Coast, runs on UK networks and needs separate coverage. If your trip crosses the border, the Ireland & UK eSIM is built for exactly that and covers the whole island on one plan.

Frequently asked questions
Does an Ireland eSIM cover Northern Ireland?
Not always. A plan sold as an Ireland eSIM usually covers the Republic of Ireland only, and Northern Ireland runs on UK networks. If your trip crosses the border, the Ireland & UK eSIM is the one to look at first, because it is sold for both jurisdictions and covers the whole island on a single plan. A multi-country Europe eSIM also works, as long as its coverage list includes the United Kingdom.
Does eSIM work in Ireland?
Yes. Ireland has full eSIM support on all three of its mobile networks, and a travel eSIM registers on them the same way a local SIM does. You need a carrier-unlocked phone that supports eSIM: iPhone XS or later, and most Google Pixel and Samsung Galaxy models from 2018 onward. If your phone shows an "Add eSIM" option in settings, it will work in Ireland.
Which mobile networks does Ireland have?
Three, Vodafone and eir operate the national networks in the Republic of Ireland, all three with 4G nationwide and 5G in cities and larger towns. Your plan connects to the network or networks listed on it, so you get local coverage without swapping anything physical.
Do I need an eSIM for Ireland if I already have EU roaming?
If your plan is from an EU or EEA country, Roam Like at Home means you use your normal allowance in Ireland at no extra cost, and you probably do not need a travel eSIM. It is worth it for everyone else: visitors from the United States, Australia, Canada and Asia usually face high per-day roaming rates, and post-Brexit some UK carriers have reintroduced EU roaming charges while others have not, so check your own tariff before you fly.
Can I buy a SIM card at Dublin Airport instead?
You can, but you pay for it in time rather than money: the shops are landside past baggage reclaim, they keep retail hours that do not cover early or late arrivals, and you have to swap out your own SIM and lose your usual number for the trip. An eSIM installs before you leave home and is working by the time you reach passport control.
How much does an eSIM for Ireland cost?
Ireland eSIM plans from SimKit range from US$1.05 to US$40.70 depending on how much data and how many days you need. The entry plan is 1 GB for 7 days at US$1.05.
Which networks do Ireland eSIMs use?
SimKit Ireland eSIMs connect to Eir, with 5G available where the network supports it. You get the same coverage as a local SIM without swapping anything physical.
Is the Ireland eSIM 5G?
Yes. Where Ireland's networks offer 5G, SimKit eSIMs use it, falling back to 4G/LTE elsewhere. Speeds depend on your device and local coverage.
How do I install and activate an eSIM for Ireland?
After you buy, open your order on the phone you'll travel with and tap the install button, or scan the QR code from another screen. The eSIM is ready in under two minutes. Activate it when you arrive in Ireland.
When should I buy an eSIM for Ireland?
Any time before you travel. The plan's validity only starts when the eSIM first connects to a network in Ireland, so you can buy as soon as you book, install on Wi-Fi at home, and it activates when you land.
Can I top up my Ireland eSIM if I run out of data?
Yes. If you run low, you can add more data to the same eSIM in a couple of taps from your account, right in the browser, without buying a new one or changing your number.
Will the eSIM work in my phone?
Most phones from 2018 onward support eSIM (iPhone XS and later, recent Google Pixel and Samsung Galaxy models) and must be carrier-unlocked. If your phone shows an "Add eSIM" option in settings, you're good.
