Pros: Lowest price per GB, fast activation, Ireland coverage on Eir. Cons: Newer brand, smaller community than Airalo.
Eir is the network available to eSIM visitors in Ireland and delivers 5G across Dublin, Cork, Galway, and Limerick. The carrier's 4G footprint covers all major motorways and intercity rail lines. Signal in coastal towns along the Wild Atlantic Way is generally solid, with the most notable gaps in the outer Aran Islands.
Coverage analysis
Eir delivers reliable 4G and 5G signal across Dublin city center, Cork's city core, and the Galway urban area. Dublin Airport (DUB) and the M50 motorway ring have full 5G coverage. The west coast from Westport to Dingle maintains 4G in town centers.
The one real limitation: offshore islands such as Inis Mor drop to 3G or lose signal on ferry crossings. EU roaming is included on all plans, which matters if you cross into Northern Ireland.
Activation
Activate your e-sim at least one hour before your flight lands at Dublin Airport (DUB). Scan the QR code in your carrier settings on any unlocked iPhone XS or newer, Pixel 3a or newer, or Galaxy S20 or newer. Your device registers on Eir automatically at arrival.
Note that Northern Ireland uses UK networks, not Irish ones, so EU roaming rules apply when you cross the border.
Data usage tips
Google Maps is the workhorse app in Ireland and uses roughly 100 MB per day for active navigation. The Transport for Ireland app pulls real-time bus and Luas tram data at about 20 MB per day. Add 150 MB per day for Instagram and light social media.
A 5 GB plan at $9.49 covers a typical 10-day holiday without video streaming. Step up to 10 GB at $16.99 if you plan to use your phone as a mobile hotspot.

What should I consider when choosing an eSIM for travel in the UK and Ireland?+

Confirm your plan includes EU roaming before you visit both regions. Tethering support matters if you travel with a laptop or tablet.

Eir delivers 5G in Dublin, Cork, Galway, and Limerick, with 4G covering all intercity motorways and most rural towns. Signal is reliable across the Ring of Kerry and the Cliffs of Moher visitor areas.
How do I get a local SIM or eSIM at Dublin Airport?+
Physical SIM cards are available at kiosks in Dublin Airport's arrivals hall, but registration requires ID and takes time — plans start at $3.49 for 1 GB. An e-sim is faster: activate before you fly, scan a QR code, and your phone connects to Eir the moment you land at DUB. No queuing, no physical card needed.
How much data do I need for Ireland?+
A 5-day city break in Dublin needs 2 to 3 GB for Google Maps, social media, and messaging. A 10-day road trip along the Wild Atlantic Way needs 5 to 7 GB, especially with photo uploads. Budget 10 GB or more for two weeks of mixed use including video calls and hotspot sharing.
Does my phone support an eSIM in Ireland?+
iPhone XS or newer, Google Pixel 3a or newer, and Samsung Galaxy S20 or newer all support eSIM in Ireland. Your device must be carrier-unlocked. Check Settings under Mobile Data for an Add eSIM or Add Plan option. Locked phones from US carriers need to be unlocked before installation.
Does an Ireland e-sim include EU roaming?+
Ireland's 1 eSIM carrier network All HelloRoam Ireland plans include EU roaming, which means your data works across EU member states. This is useful if you extend your trip to France, Germany, or other European destinations. Note that Northern Ireland uses UK networks, not EU ones, so roaming terms differ at that border.
Can I use my Ireland eSIM for a road trip along the Wild Atlantic Way?+
Eir covers all major towns along the Wild Atlantic Way from Donegal to Cork — plans start at $3.49 for 1 GB. Signal in Clifden, Westport, and Dingle town centers is solid 4G. Remote stretches between villages can drop to 3G. A 10 GB plan at $16.99 gives you enough buffer for navigation, photos, and occasional video calls along the full route.
Is an eSIM or local SIM card better for visiting Ireland?+
An eSIM is better for most international visitors — plans start at $3.49 for 1 GB. You install it before departure, skip the airport SIM queue, and get connected to Eir 5G immediately at DUB. The 5 GB plan at $9.49 is competitive with airport SIM pricing and includes top-up and tethering. Local SIMs need ID registration and a physical nano-SIM slot.
