An Ireland eSIM is an easy way to have maps and messages ready for the trip. The harder part is choosing a plan that fits where you are going. A weekend in Dublin, a month with a laptop and a drive from Galway to Belfast call for different things.
Start with the country list. The Republic of Ireland and Northern Ireland are different coverage destinations. Belfast is in the UK, so an Ireland-only package may leave you without usable data there. The phone does not necessarily lose signal at the exact border, but you should arrange UK coverage before heading north.
For official destination information, attractions and itinerary planning across the island, see the official Tourism Ireland website. This independent government-supported travel resource is useful when planning stops around Dublin, the Wild Atlantic Way and Northern Ireland.
My starting point for a Republic-only trip is Ubigi: 10GB for €12 over 30 days, or its €49 unlimited month with an important 60GB full-speed allowance. Nomad is competitive at 20GB, while the other choices suit different priorities. I lived in Ireland for three years on a Three Ireland plan; that experience informs the practical advice here, but it is not a field test of these five travel eSIMs in Ireland. Continuing on? UK 2026 · Scotland 2026 · Europe 2026.



⚡ Best eSIM for Ireland 2026: Quick Answer
🥇 My value pick: Ubigi, Eir + Three, 5G where available. 10GB/30 days €12; unlimited/30 days €49, with 60GB total before 2Mbps.
📶 Good 20GB value: Nomad eSIM, Three + Eir, 5G listed. 20GB/30 days €17.79, a fixed allowance without a daily reset.
🏆 Unlimited phone data: Holafly, Three + Vodafone. €3.79 for one day or €68.90 for 30 days; carrier fair use and 1GB/day hotspot apply.
🔒 Daily allowance and security extras: Saily, 5GB/day before up to 1Mbps on unlimited plans. 1GB/7 days €3.49; optional US number, not Irish.
🌍 Local or regional choice: Airalo, Ireland 50GB/30 days €39 on Three 4G. Its EU+UK product is a separate purchase for broader trips.
⚠️ Visiting Northern Ireland? Confirm that the selected package includes both Ireland and the UK. A regional name alone is not enough.
✈️ Install on reliable Wi-Fi before flying. Check when your provider starts the validity period, then select the travel eSIM for data on arrival.
Install Your Ireland eSIM Before You Land
Check that your phone is unlocked and supports eSIM, then follow the provider’s installation instructions while you have reliable internet. Installation and activation are not always the same step. Keep the confirmation email and setup instructions available offline, and check the purchase-to-activation deadline. The five provider videos below remain useful setup companions.
On arrival, choose the travel eSIM for mobile data and enable data roaming if its instructions require it. Turn off data roaming on your home SIM and disable automatic mobile-data switching to avoid unexpected charges. You can keep your home number available for calls and 2FA, but your home operator’s rates still apply. Setup guide: How to Activate an eSIM. Label the plans clearly if you also buy UK coverage.

How I would read these tables: compare the validity first, then the allowance. Ubigi’s 10GB costs €9 for seven days or €12 for 30. Nomad’s €17.79 buys 20GB for 30 days. Those fixed plans can be easier to budget than unlimited packages whose faster data resets daily or runs out partway through the trip.
At 50GB, Airalo and Ubigi now tie at €39 for 30 days. Saily has the lowest 1GB price among these five, €3.49 for seven days. Its 5GB daily allowance is useful for regular daily use; Ubigi’s unlimited allowance is a total for the entire package, so the two work differently.
Holafly charges €68.90 for 30 days and allows 1GB of hotspot sharing each day. Its phone data remains subject to carrier fair use. These are base prices before coupons; a low headline price is only useful if the plan covers your route and the way you use data.

Best eSIM for Ireland 2026: The 5 Providers in Detail
Ubigi is my first price check for the Republic of Ireland. It lists Eir and Three with 5G access where available, and its 10GB/30-day package costs €12. That compares with €14.23 at Nomad, €15.99 at Saily and €16 at Airalo for the same allowance and validity.
For a week, Ubigi’s 10GB package drops to €9. I would start there for maps, messages and ordinary phone use, then look at a larger allowance if I planned to share data with a laptop or upload a lot of video.
The unlimited packages cost €19 for seven days, €29 for 15 days and €49 for 30 days. The monthly price is €19.90 lower than Holafly’s, about 29% less, but the fair-use rules differ. A cheaper month is not the same product just because both providers use the word unlimited.
Ubigi publishes the limits: 20GB total on seven days, 30GB total on 15 days and 60GB total on 30 days, then 2Mbps. These are whole-plan allowances, not daily quotas. Hotspot use counts toward them. SmartStart begins the package when it connects at the destination; the purchase must be activated within the stated six-month window. Its reusable profile can take later packages.
I have not personally tested Ubigi. The recommendation comes from its current price, listed networks and published conditions. Coverage and speed still depend on the location, phone and available network. Full review: Ubigi Review 2026.
| Ubigi plan | EUR price | Condition / comparison |
|---|---|---|
| 3GB / 15 days | €7.00 | Fixed allowance |
| 10GB / 30 days | €12.00 | Nomad €14.23; Saily €15.99 |
| 10GB / 7 days | €9.00 | Shorter validity |
| 50GB / 30 days | €39.00 | Ties Airalo at €39 |
| Unlimited / 7 days | €19.00 | 20GB total, then 2Mbps |
| Unlimited / 15 days | €29.00 | 30GB total, then 2Mbps |
| Unlimited / 30 days | €49.00 | 60GB total, then 2Mbps; €19.90 below Holafly |
Best for: a Republic-only trip where price matters, especially 10GB for a week or a month. For heavy use, compare the total full-speed allowance with your expected usage. Reader code: ANDREONDIGITAL for 10% off eligible purchases.
Watch: How Ubigi eSIM Works for Ireland
Keep this Ubigi video as a setup reference. Use the current tables above for prices and allowances, since an embedded video can predate a plan change.
Install the profile on Wi-Fi, follow the SmartStart instructions and choose it as the data line when you arrive. Check the package’s destinations before reusing it for a later journey; the reusable profile does not give every purchased plan worldwide coverage.
Nomad’s current Ireland listing names Three and Eir, with 5G. My connection to Three is personal: I lived in Ireland from July 2022 to October 2025 and used a Three Ireland plan throughout. Where I lived had no home Wi-Fi, so I used it for the laptop as well as my phone. It served me well in Dublin.
That history makes the network familiar, but a travel eSIM can have different routing and service conditions from a local contract. I have used Nomad in Portugal, not tested its Ireland package across the Wild Atlantic Way. I would still check the planned overnight stops on the coverage map before choosing a network for a road trip.
Nomad’s strongest fixed-data offer here is 20GB for €17.79 over 30 days, below Saily’s €22.99 and Airalo’s €23.50 for their 30-day 20GB plans. The allowance does not reset daily, which suits uneven use: a quiet day sightseeing followed by an evening catching up on work.
Its unlimited plans work differently: 2GB per day, then 1Mbps. The seven-day price is €22.24. For someone who expects several heavy days, I would compare a fixed allowance first rather than assume unlimited means unrestricted speed.
Nomad’s 20GB option is a sensible middle ground for many trips. Its help centre permits hotspot sharing, with device and network compatibility caveats; shared data uses the plan allowance. The choice is about the amount and validity, not a promise of full speed everywhere. Full review: Nomad eSIM Review 2026.
| Nomad plan | EUR price | Condition / comparison |
|---|---|---|
| 1GB / 7 days | €4.00 | Fixed allowance |
| 10GB / 30 days | €14.23 | Ubigi €12 |
| 20GB / 30 days | €17.79 | Lowest 30-day 20GB price among these five |
| 50GB / 30 days | €40.03 | Ubigi and Airalo €39 |
| Unlimited / 7 days | €22.24 | 2GB/day, then 1Mbps |
Best for: travelers who want 20GB for a month and prefer a single fixed allowance. Reader code: ANDRE15 for 15% off eligible purchases.
Watch: How Nomad eSIM Works for Ireland
This Nomad video is a companion to installation and app setup. The network and price details in this article were checked separately against the current Ireland product listing.
Follow the plan’s activation notice. The current listing starts validity on connection to a supported network, or automatically after 60 days if unused. Installing well before a trip is useful, but buying months ahead without checking that deadline can waste part of the plan.
Holafly lists Three Ireland and Vodafone Ireland, with 4G/5G where available. That is a different carrier pairing from Ubigi and Nomad. It gives another option when comparing coverage at your stops, although two listed networks do not guarantee signal in every building, valley or coastal stretch.
Its unlimited phone data is subject to the local network’s fair-use policy. Holafly does not give a fixed numeric phone-data threshold on this Ireland page. The separate hotspot allowance is 1GB per day, which matters if your laptop needs more than occasional access.
I have used Holafly myself in Portugal, Turkey and Thailand. Those experiences are covered in my review; they are not Ireland speed tests. Here, I would consider it for someone who prefers choosing an exact trip length and mainly uses data on the phone.
The 30-day plan costs €68.90, compared with Ubigi’s €49. Holafly also promotes Always On backup data, subject to its own conditions. One eligibility detail deserves attention: its FAQ excludes domestic use and treats the EU as the domestic area for EU residents. If you live in the EU, confirm eligibility with Holafly before buying this Ireland plan. Full review and comparison: Holafly Review 2026 · Holafly vs Nomad.
| Holafly unlimited | EUR price | Condition / comparison |
|---|---|---|
| 1 day | €3.79 | One-day total, not the daily rate for every duration |
| 5 days | €18.50 | 1GB/day hotspot |
| 7 days | €25.50 | Carrier fair use |
| 15 days | €46.90 | Ubigi €29 with a different fair-use allowance |
| 30 days | €68.90 | Prepaid trip plan; check EU-resident eligibility |
Best for: eligible visitors who want unlimited phone data and can work within a 1GB daily hotspot allowance. Reader code: ANDREONDIGITAL for 5% off eligible purchases.
Watch: How Holafly eSIM Works for Ireland
The Holafly video remains here for the purchase and setup process. Check the dated Ireland tables and the current order conditions for the plan you actually choose.
Install on reliable Wi-Fi and activate according to the instructions when you reach the destination. Check the country’s inclusion, residency restriction and hotspot allowance before paying. If your journey includes Belfast, arrange a package that explicitly includes UK coverage.
Saily’s unlimited option allows 5GB each day before reducing speed to up to 1Mbps. The five-day plan is €16.99, seven days €23.99 and 30 days €63.99. The daily reset can be useful for someone whose data use is fairly steady through the trip.
Saily permits hotspot sharing without a separate tethering quota, but it still uses the package’s data allowance and speed limit. Its smallest fixed package is 1GB for seven days at €3.49. The optional calls-and-texts service provides a US number, not an Irish number, and has separate purchase and identity-verification requirements.
The app includes virtual-location, ad-blocking and web-protection features. Those extras may be useful, but the eSIM purchase is not a full NordVPN subscription.
Saily does not name the Irish partner carrier on the destination page. It describes speeds as dependent on the local provider and available coverage, so I cannot assign it to Three, Vodafone or Eir. If a specific network is essential for a remote stay, the named-network alternatives are easier to assess before buying.
I have not personally tested Saily. The comparison here is based on the current official listing and package selector. Full review: Saily eSIM Review 2026.
| Saily plan | EUR price | Condition / comparison |
|---|---|---|
| 1GB / 7 days | €3.49 | Lowest 1GB price among these five |
| 10GB / 30 days | €15.99 | Fixed allowance |
| 20GB / 30 days | €22.99 | Nomad €17.79 |
| Unlimited / 5 days | €16.99 | 5GB/day, then up to 1Mbps |
| Unlimited / 7 days | €23.99 | Hotspot uses the same allowance |
| Unlimited / 10 days | €30.99 | 5GB/day, then up to 1Mbps |
| Unlimited / 30 days | €63.99 | Optional US number is a separate service |
Best for: visitors who value the 5GB daily allowance, hotspot sharing and the app’s security extras. Reader code: ANDREONDIGITAL for 10% off eligible purchases.
Watch: How Saily eSIM Works for Ireland
This Saily video covers app-based installation. Keep the app available before departure and refer to the current plan details for its allowance, validity and activation conditions.
The current plan selector says unused plans activate automatically after 180 days, while the same destination page still has a FAQ referring to 30 days. Follow the deadline in your purchase confirmation and ask Saily if those notices conflict. The Ireland package excludes the UK, including Northern Ireland.
Airalo’s Ireland package lists Three at 4G. Its 5GB/seven-day option is €9.50, while 50GB/30 days costs €39, the same base price as Ubigi’s 50GB plan. Top-ups are offered for the listed Ireland eSIM; check the available package in the app rather than assuming every future top-up will keep the same price.
For a journey that also includes Northern Ireland, Airalo sells EU+UK and Europe regional products separately. Check their country lists for Ireland and the United Kingdom before purchase. Buying the local Ireland product does not automatically include those regional destinations.
That distinction is useful when planning Dublin and Belfast on the same trip. Compare the regional package against two local packages for the dates and data you need, rather than choosing the cheapest Ireland listing and hoping it covers the whole island.
At 10GB for 30 days, Airalo costs €16; Ubigi is €12. At 20GB for 30 days, Airalo is €23.50 and Nomad €17.79. Airalo’s local unlimited plans allow 3GB per day before 1Mbps. Its local product explicitly excludes Northern Ireland. Full review: Airalo Review 2026.
| Airalo product | EUR price | Condition / comparison |
|---|---|---|
| Ireland 5GB / 7 days | €9.50 | Local data-only plan |
| Ireland 10GB / 30 days | €16.00 | Three 4G |
| Ireland 50GB / 30 days | €39.00 | Ties Ubigi for 50GB |
| EU+UK regional | Check selected package | Separate product; verify Ireland and UK on the country list |
| Europe regional | Check selected package | Separate product; check countries and package conditions |
Best for: visitors comparing a short fixed package, a 50GB allowance or a separate regional plan for a wider itinerary. Reader code: ANDRE15 for 15% off eligible purchases.
Watch: How Airalo eSIM Works for Ireland
The Airalo video explains purchase and installation. Before following the steps, make sure the package in your account matches the destinations on your itinerary.
The current local Ireland package starts on first connection to a supported network and is data-only. Airalo permits personal hotspot when the device and network support it; shared data uses the same allowance. Set the eSIM as the data line and follow its roaming and APN instructions. A regional package must list both Ireland and the UK if you expect to use it on both sides of the border.
Ireland and Northern Ireland: Check Your Plan Before Driving North
The island has two jurisdictions. The Republic of Ireland has 26 counties, uses the euro and is an EU member. Northern Ireland has six counties, is part of the United Kingdom and uses pound sterling. For a mobile-data purchase, the practical consequence is that an Ireland destination listing may cover only the Republic.

| Plan type | Republic of Ireland | Northern Ireland |
|---|---|---|
| Ireland local package | Check Ireland in coverage | Do not assume inclusion; Airalo and Saily explicitly exclude it |
| UK local package | Do not assume inclusion | Check UK coverage and partner networks |
| Airalo EU+UK regional | Check current country list | Check current country list |
| Europe regional eSIM | Must explicitly list Ireland | Must explicitly list United Kingdom |
| Global eSIM | Must explicitly list Ireland | Must explicitly list United Kingdom |
For Belfast, the Giant’s Causeway, the Causeway Coastal Route or Derry/Londonderry, check for explicit UK coverage. You can choose a regional package that lists both destinations or use separate Ireland and UK packages. A signal from the other side of a border may remain visible for a while; that does not change what the plan includes.
My own expensive roaming lesson happened elsewhere: I ran up a €101 overage while using my Irish Three plan after I was already living in Portugal. It was not a Northern Ireland border charge. It taught me to read the limits of the plan I was using rather than assume that familiar roaming arrangements would cover every situation.
Choose the right destinations, then check your phone’s settings as well. Keeping the home SIM active can still create charges for calls, messages or accidental data use. For the UK part of the trip: Best eSIM for the UK 2026.
Wild Atlantic Way: Plan for Gaps Along the Coast
The Wild Atlantic Way follows roughly 2,500km of coastline from Donegal to Cork. A route that long takes you through towns as well as exposed headlands, valleys and ferry crossings. I would plan around the places I actually need a connection, especially the accommodation and any stops where I expect to work.

Use ComReg’s official coverage map to check the Republic’s networks at those locations. It predicts outdoor coverage, not a guaranteed result inside a cottage or on a boat. Save booking details and maps offline, and ask your accommodation which network works there. WhatsApp is useful when a business offers it, but keep its phone number too.
Ireland’s Three Networks Explained (and the 2026 Changes)
Eir’s phased 3G switch-off started on 1 October 2026. Its official schedule lists affected areas and dates, so check that schedule if you rely on an older handset. For this comparison, what matters is the generation actually supported by the travel plan: Airalo’s Ireland listing says 4G, while Ubigi, Nomad and Holafly list 5G access where available.
An eSIM is a way to provision a mobile line, not a guarantee of a newer radio connection. Both physical SIMs and eSIMs need a compatible phone, supported frequencies and an available network. If you also need ordinary voice calls, check the device and voice support separately from mobile data.
| Provider | Listed Ireland network(s) | Generation listed | What to consider |
|---|---|---|---|
| Ubigi | Eir + Three | 5G where available | Price and total fair-use allowance |
| Nomad eSIM | Three + Eir | 5G where available | 20GB fixed allowance |
| Holafly | Three + Vodafone | 4G/5G where available | Fair use, hotspot and residency eligibility |
| Airalo Ireland | Three | 4G | Local package differs from regional products |
| Saily | Not named | Depends on local provider and coverage | Daily allowance and unnamed partner network |
Tips for Using an eSIM in Ireland
Before the flight: install on reliable Wi-Fi, save the instructions, and check the activation deadline. Before driving north: check UK coverage and home-SIM roaming settings. Do not rely on an assumed airport kiosk service or on the phone staying on the same network after you cross the border.
For a rural stay, the exact address is more useful than a national coverage claim. Check ComReg, ask the host, and keep an offline backup. My good experience with Three in Dublin is useful context, but it cannot tell you whether a particular coastal room has usable signal.
Download maps before remote driving stages and ferry journeys. Keep a power bank handy for long days of navigation, and save important reservations offline. WhatsApp can keep your existing account working over the eSIM’s data without changing your number. For wider trips: Europe 2026 · Scotland 2026 · 30 Days in Europe.
FAQ: Best eSIM for Ireland 2026
Final Verdict: Best eSIM for Ireland 2026
I would choose the plan after the route. For a Republic-only holiday, it is easy to spend more on data than you need. For a trip that includes Belfast, an inexpensive Ireland package can be the wrong purchase before you have used a single megabyte.
- 🥇 Ubigi: my first value check, with 10GB/30 days at €12 and unlimited/30 days at €49. The latter includes 60GB total before 2Mbps. Code ANDREONDIGITAL: 10% off eligible purchases.
- 📶 Nomad eSIM: 20GB/30 days for €17.79 on the listed Three + Eir networks. A useful fixed allowance if your daily usage varies. Code ANDRE15: 15% off eligible purchases.
- 🏆 Holafly: unlimited phone data, subject to carrier fair use, with 1GB/day hotspot. €3.79 for one day or €68.90 for 30. Check the EU-residency restriction. Code ANDREONDIGITAL: 5% off eligible purchases.
- 🔒 Saily: 5GB/day before up to 1Mbps on unlimited plans, starting at €16.99 for five days. The optional number is US, not Irish. Code ANDREONDIGITAL: 10% off eligible purchases.
- 🌍 Airalo: 50GB/30 days at €39, plus separate regional products to compare for Ireland and UK travel. The local package is Three 4G and excludes Northern Ireland. Code ANDRE15: 15% off eligible purchases.
For a week with maps, messaging and restaurant searches, I would begin with Ubigi’s 10GB/7 days at €9. If I expected more data over a month, Nomad’s 20GB at €17.79 would be my next comparison. For laptop use, I would estimate the workload before choosing between a fixed plan and a daily or total fair-use allowance. Holafly’s 1GB hotspot ceiling needs particular care. And for Dublin plus Belfast, I would settle the Ireland-and-UK country list first, then compare price. That is a more useful decision than choosing a provider solely because it says unlimited or 5G.

Prices are in euros (€), before coupons, and were checked against official provider listings on 22 October 2026. Coupon eligibility and final checkout prices can change. I’m Brazilian and live in Belgium; I lived in Ireland from July 2022 to October 2025 and used Three Ireland throughout that period.
I’ve personally tested Nomad in Portugal (Porto, Lisbon and Figueira da Foz), Holafly in Portugal, Turkey and Thailand, and Airalo in Figueira da Foz. I have not personally tested Ubigi or Saily. My Ireland experience was with a local Three Ireland plan, not an Ireland field test of these travel eSIMs.
Networks checked on the official Ireland listings: Ubigi, Eir + Three; Nomad, Three + Eir; Holafly, Three + Vodafone; Airalo, Three 4G. Saily does not name the Irish carrier. A listed network or 5G option does not guarantee the same connection at every stop.
Fair-use comparison: Ubigi has total allowances of 20GB, 30GB and 60GB on its seven-, 15- and 30-day unlimited packages, then 2Mbps. Nomad allows 2GB/day before 1Mbps; Airalo Ireland allows 3GB/day before 1Mbps; Saily allows 5GB/day before up to 1Mbps. Holafly applies carrier fair use and separately allows 1GB/day hotspot.
For Northern Ireland, confirm explicit UK coverage on the selected package. For older devices, check Eir’s ongoing 3G switch-off schedule. Recheck price, eligibility, activation and network details before purchase, particularly if buying well ahead of departure.
