What Is an Ireland eSIM?

An Ireland eSIM is a digital data plan that gives your phone mobile internet across Ireland without a physical SIM card. You buy a plan, scan a QR code, and you are online. No plastic SIM, no airport queues.

Your home SIM stays in your phone, so you keep your normal number for calls and texts while the eSIM handles data. Cheaper than roaming, faster than finding a SIM shop when you land.

Strongest network, chosen automatically Connects to the strongest network in each area for fast 4G LTE and 5G data wherever you are.
  • No Physical SIM Card100% digital, delivered as a QR code
  • 4G LTE + 5G SpeedConnects to whichever operator is strongest nearby
  • Keep Your Home NumberDual SIM, so calls and texts still reach you

Getting connected

From checkout to signal in three steps

Buying and installing takes about five minutes. The only waiting happens after you land.

Buy before you fly Choose your plan and the QR code arrives by email within a minute or two. It also sits in your account as a backup.
Install while you have Wi-Fi Scan the code from your phone settings. Do this at home the night before rather than in an arrivals hall with no signal.
Land, then switch on data roaming Turn on data roaming for the eSIM line when you arrive. Your plan activates on a local network and the clock starts then, not before.

Staying Online in Ireland: A Place by Place eSIM Guide

Ireland is small, but the way it feels online changes a lot from a Dublin cafe to a quiet road in Kerry. This guide walks through the country region by region so you know what to expect before you go. Our eSIM connects to the Eir network, and you can start a plan from as little as $1.29.

01 What is the best eSIM for Ireland?

The one on a big Irish network with checkout prices that match the page. Ours runs on Eir 5G, starts at $1.29 for 1 GB over 7 days, and 10 GB for a month is $5.99. Airalo charges $17 for that same 10 GB and Saily $17.99, as the comparison further down shows.

02 The short answer

If you are visiting from outside the EU, a travel eSIM is the cheapest and easiest way to get online in Ireland, and the price differences between brands are huge. Our Ireland eSIM starts at $1.29, and 10 GB for a month costs $5.99. Airalo charges $17 for the same 10 GB, Saily $17.99, Nomad $16. Same island, same networks.

One honest exception before we go further: if you live in the EU your home plan already roams free in Ireland, and if you are visiting from the UK, the big four British carriers all treat the Republic of Ireland like home too. This guide is for everyone else, especially visitors from the US, Canada and Australia.

03 Mobile internet in Ireland: what you are working with

Ireland has three real networks: Three, Vodafone and Eir. All three are solid in Dublin, Cork, Galway and Limerick, and 5G is widely built out. Eir claims 5G coverage reaching 99 percent of the population, Vodafone has the reputation for the widest rural signal, and Three holds the most spectrum.

The honest part: on the Wild Atlantic Way, in Connemara, on the Ring of Kerry mountain stretches and in rural Donegal, every network has dead spots between towns. That is not a SIM problem, it is a geography problem. Download offline maps for the road trip days and you will be fine.

Our eSIM runs on Eir with 5G included, which covers the cities, the east coast and the main tourist routes well.

This is where the numbers get ugly. Verizon TravelPass is $12 a day in Ireland. AT&T's International Day Pass is $10 a day. On a 10 day trip that is $100 to $120 for data you could have for six dollars. T-Mobile includes some international data on certain plans, but at reduced speed unless you pay for the day pass. Hotel wifi will not save you on the cliff walks either.

04 Option 1: buying a local SIM card in Ireland

Ireland does local SIMs pretty well, and if you are staying a month or more they are worth a look:

  • Three sells a tourist pack: 5 GB for 7 days at 15 euro (about $17), or 25 GB for 28 days at 25 euro (about $29). Their standard prepay at 20 euro includes their famous all you can eat data.
  • Vodafone has a tourist eSIM at 20 euro (about $23) with unlimited 5G data for 28 days.
  • Eir prepay starts around 10 euro with unlimited data offers on top.

Sounds good, so what is the catch? Three things. You need to find a store or a vending machine at Dublin Airport and deal with it after a long flight, the airport machines carry a markup, and every one of those prices is higher than a travel eSIM for the amount of data a normal one or two week visitor actually uses. A 25 euro tourist pack only wins if you genuinely chew through 25 GB.

A travel eSIM is a digital SIM you buy online before flying. Scan a QR code at home on wifi, land at Dublin Airport, and your phone connects to an Irish network while everyone else is still queueing at the SIM vending machine.

Every big brand sells one for Ireland. The product is nearly identical, the prices are not.

Staying a month or more and streaming heavily? Vodafone's 20 euro unlimited tourist eSIM is a fair deal, and we will not pretend otherwise.

For a normal holiday, one or two weeks, the eSIM wins on every axis. You set it up before you fly, it costs less than a coffee, and you skip the airport errand completely. Even our biggest plan, 10 GB for a month at $5.99, costs less than one single day of Verizon roaming.

05 Price comparison: MegaEsim vs Airalo, Saily, Nomad and Holafly

Prices checked in 2026. All plans are data only and run on the Irish networks.

  MegaEsimBest choice Airalo Saily Nomad Holafly
1 GB, 7 days$1.29$4.50$3.99$4.50unlimited only
10 GB, 30 days$5.99$17.00$17.99$16.00unlimited only
Unlimited, 7 days$6.17from $10.50 for 3 days$34.99 for 10 days$11 to $33$27.30
10% discount codeMEGA10

Ten gigabytes for a month costs $5.99 with us and $16 to $18 with the household names. Even Ireland's own tourist SIMs cost double or triple for comparable data. The big brands are not selling better coverage, they are selling their ad budget back to you.

On unlimited plans: Holafly sells unlimited only, from around $3.90 per day for a week, which is $27.30 before you have bought a single pint. Our unlimited plans start at $1.299 a day with a clear fair use note on every plan.

06 How Much Data to Buy and How to Turn It On

Light users who mostly check maps and messages get by on a few hundred MB a day. If you stream music in the car, upload photos and use your phone as a hotspot, plan for closer to 1 GB or more each day. A one week road trip across several regions sits comfortably on the 5 GB or 10 GB plans.

Setup takes a couple of minutes. Buy the plan, scan the QR code we send, and the eSIM installs itself. Leave airplane mode on during the flight, then switch it off after you land in Ireland. Turn on data roaming for the new eSIM line and you are connected to Eir straight away.

Compared with a paper SIM from an airport kiosk, you skip the queue and the passport form. Compared with daily roaming charges from your home carrier, you usually pay far less, with the cheapest plan starting at just $1.29.

  • Light use (maps, messages, email): 1 GB a week, $1.29 with us.
  • Normal use (maps all day, Instagram, bus apps, video calls home): 3 to 5 GB, ours cost $2.24 and $3.33 for a month.
  • Heavy use (streaming, hotspot, remote work on the go): 10 GB at $5.99, or unlimited from $1.29 a day.

Ireland is compact and wifi is common in pubs and hotels, so most visitors sit comfortably in the middle band. If you plan to navigate the whole Wild Atlantic Way by phone, size up and download offline maps as backup for the dead zones.

07 Landing in Dublin and Finding Your Feet

Most trips start at Dublin Airport. The smart move is to install the eSIM at home and switch it on once you land. Your phone picks up Eir as soon as you turn off airplane mode, so you can order a taxi or a Bolt ride before you even reach the bus.

Dublin has the strongest signal in the country. You get fast 4G and 5G across the city centre, from Temple Bar to St Stephen's Green to the Guinness Storehouse. For a short city break of two or three days, the 1 GB for 7 days plan at $1.29 is often enough if you use hotel and cafe wifi for heavy stuff.

Cork city runs smoothly on Eir. You will have good data in the English Market, around the university, and out at Cobh where many cruise ships dock. Maps and ride apps work fine here.

Once you head out toward Kinsale or the smaller harbour towns, the signal stays usable but drops in pace on some back roads. A 5 GB plan covers a week of maps, photos and light browsing across the south with room to spare.

Galway is a great base and the network holds up well in the city, from Eyre Square to the Latin Quarter. Buskers, pubs and food stalls keep you busy, and your data keeps pace.

Galway is also where many people start a longer western trip. If that is you, think about a bigger plan now. The 10 GB for 30 days plan at $5.99 is a solid pick for anyone touring for a few weeks, since you will lean on maps far more once you leave the city.

This is the part of Ireland where signal gets honest. Along the main route through Clare, Mayo and Donegal you will usually have data, and the Cliffs of Moher are well covered. But the road dips in and out of valleys and headlands, and on the most remote stretches the bars fall away.

The fix is simple. Download your route as an offline map before you set off each morning. That way a quiet patch near a cliff or a beach does not leave you guessing. Your data comes back the moment you reach the next town.

The Ring of Kerry, the Dingle Peninsula and Connemara are the postcard parts of Ireland. They also have the patchiest mobile signal. You will get coverage in Killarney, Dingle town and Clifden, and on much of the main loop, but expect gaps on the high passes and remote inlets.

Plan for this rather than fight it. Save your bookings, directions and a few playlists offline before you drive out. When you do have signal, a 3 GB for 15 days plan at $2.10 is plenty for checking in, sharing a few photos and looking up the next stop.

08 SIM card or eSIM for Ireland?

If you are weighing the best SIM card for Ireland against an eSIM, the practical answer is that they ride the same Irish networks, so coverage does not decide it. What decides it is arrival: an eSIM installed at home is working when you switch off airplane mode at Dublin Airport, while a physical SIM means finding a Three or Vodafone shop in the city, since the airport options are limited and pricier. For a stay under a month with a modern phone, the eSIM is simply less friction for the same signal.

Dublin itself is blanket coverage on every network, including the DART line, the city centre and the suburbs, so no choice you make here can really go wrong inside the city. The differences only appear out west, which the coverage section above covers honestly.

09 The bottom line

Ireland is an easy country to stay connected in, and an easy country to overpay in. American roaming passes cost $100 or more per trip, local tourist SIMs cost 15 to 25 euro plus an airport queue, and the famous eSIM brands charge three times our price for identical data. Our Ireland eSIM gives you the Eir network with 5G, 10 GB for $5.99, and a QR code in your inbox before you finish packing.

Safe travels. The cliffs really are that green, and yes, your phone will survive the rain.

Frequently Asked Questions

Everything you need to know about our Ireland eSIM.

One on Eir 5G that installs from a QR code before you fly. Ours costs $1.29 for 1 GB over 7 days or $5.99 for 10 GB over a month, and the price on the page is the price at checkout.

It connects to Eir, one of Ireland's main mobile networks. Eir gives you strong 4G and 5G in cities like Dublin, Cork and Galway, and good coverage across most towns and main roads.

Most phones from the last few years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Your phone also needs to be carrier unlocked. If you are not sure, check your phone settings for an option to add an eSIM or contact your carrier before you travel.

Yes. The eSIM runs alongside your home SIM, so you keep your own number for calls and texts and use the Ireland eSIM for data. Many travelers leave their home line on wifi calling and use the eSIM for everything online.

Eir issues eSIMs to its own prepay and bill pay customers, normally through an Eir store or the Eir app, and the prepay packs are bought in Ireland. For a visit, our eSIM uses the Eir network and installs before you land, with no store visit and no Irish account to open.

No. Ours is a travel eSIM that connects to Eir’s network, so the coverage is Eir’s, but the plan, the price and the support are ours, and there is no Irish phone number. Your home SIM stays in the phone for calls and bank codes.
