737 of these 1606 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1606 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Ireland: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Ireland is Yatelo with 20 GB for 30 Days at $6.99. That is $0.35 per GB, the best rate of the 1606 plans we compare from 58 providers. 1027 plans include 5G. 596 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Ireland?
There is no single best eSIM for Ireland, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1606 plans on the numbers, as they stand on 17 October 2026:
- Best value overall Yatelo, 20 GB for 30 Days at $6.99. That is $0.35 per GB, the lowest real rate of every Ireland plan we track.
- Best for a short trip eSIM4Travel, 1 GB for 7 Days at $0.69. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Highest daily cap on an unlimited plan ByteSIM, 30 Days at $78.90, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Yatelo did not pay to be named here.
Which mobile networks does Ireland have?
More than 90% of the population has access to 4G. Geographic coverage is much lower than population coverage, and signal can drop to basic levels in hilly or mountainous terrain outside towns.
- Vodafone: Vodafone is one of the big three networks and has 5G live in selected areas across all 26 counties.
- Three: Three has been ranked the fastest network nationwide for five straight years in independent testing and claims 92% population coverage on 5G after a 2 billion euro network investment.
- Eir: Eir is the former state incumbent and is recognised as the leader in 5G availability according to independent testing.
MVNOs hold 15.4% of the Irish market as of Q3 2025, and budget brands like GoMo (on Eir), 48 and Tesco Mobile (on Three) and Sky Mobile (on Vodafone) offer cheap no contract plans.
The eSIM plans we compare on this page connect to:
The list above is Ireland's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Ireland?
All three networks run 5G. Three claims 92% population coverage, Vodafone has 5G in every county and Eir leads on 5G availability in independent tests, but rural areas often fall back to 4G.
How much data do you need in Ireland?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Ireland right now:
Are unlimited eSIMs for Ireland really unlimited?
Not always. 729 of the 1606 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 36 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Ireland the caps we can see published are 0.3 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.35 per GB from Yatelo, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Ireland?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Ireland starts at $0.20 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Ireland eSIM
Pick the plan, not the brandThe cheapest rate in Ireland today is $0.35 per GB from Yatelo, against a median of $1.25. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Ireland is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to 3, Eir, Eircom Limited, Meteor, Three Ireland, Vodafone. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out596 of the 1606 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Good to know before you land in Ireland
EU visitors can simply roam on their home plan under EU roam like home rules, so a local SIM only makes sense for non EU travellers or heavy data users.
Dublin Airport sells physical SIMs from Sim Local vending machines and shops (WHSmith in Terminal 1, the SPAR by arrivals in Terminal 2) covering Vodafone, Three and Lycamobile. They are tourist friendly and you do not need to be an Irish resident.
Coverage is strong in Dublin and other cities but gets patchy in hilly rural areas, especially in the west. Three's speed record makes it a solid default for tourists.
Ireland Travel eSIM FAQ
Everything you need to know about using an eSIM in Ireland
What is the cheapest eSIM for Ireland?
Right now the cheapest option ranked by price per GB is Yatelo with 20 GB for 30 Days at $6.99. That works out to $0.35 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for Ireland?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for Ireland is Yatelo at $0.35 per GB, the lowest real rate of the 1606 plans we compare. For heavy daily use there are 729 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in Ireland?
Yes. We track 1606 prepaid travel eSIM plans from 58 providers that work in Ireland, roaming onto 3, Eir, Eircom Limited, Meteor, Three Ireland, Vodafone. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in Ireland?
The plans we compare connect to 3, Eir, Eircom Limited, Meteor, Three Ireland, Vodafone. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Ireland eSIMs support 5G?
1027 of the 1606 plans we track for Ireland include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy an Ireland eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Ireland. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Ireland eSIM if I run out?
Yes. 596 of the 1606 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in Ireland?
For a trip of days or weeks, usually yes. Data for Ireland starts at $0.20 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does an Ireland eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in Ireland?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Which Ireland eSIM gives the most data per day?
Of the plans sold as unlimited here, ByteSIM allows the most at full speed, 10 GB a day from $4.90. The smallest allowance on this page is 300 MB a day, from 4 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
