Cheapest eSIM for Ireland: the numbers
As of 31 August 2026, 15:21 GMT, the cheapest eSIM for Ireland is eSIMCard with 100 GB for 31 Days at $35.41. That is $0.35 per GB, the best rate of the 172 plans we compare from 9 providers. 117 plans include 5G. 55 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
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.

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. 29 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in Ireland?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Ireland starts at $35.41 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
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
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.

Everything you need to know about using an eSIM in Ireland
What is the cheapest eSIM for Ireland?

Which networks will my eSIM connect to in Ireland?

Do Ireland eSIMs support 5G?
117 of the 172 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 top up my Ireland eSIM if I run out?
Yes. 55 of the 172 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.
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.
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 MegaEsim at $2.87.
