🇮🇪 eSIM for Ireland
A UK plan does not cover Ireland, and an Irish plan does not cover Northern Ireland or Britain — a detail that catches many visitors. An Ireland eSIM covers the Republic properly.

Using your eSIM in Ireland
3, Eir and Vodafone are the operators listed on our Ireland plans; you do not choose between them, the phone does. Every plan in the table is sold as 3G/4G/5G, so a 5G phone will use 5G where the local network has it.
The smallest plan is 500 MB over 1 day ($3.28); the largest is 100 GB over 180 days ($140.08). Every plan here can be topped up from the app without reinstalling anything.
Practical notes for Ireland
- Coverage is good in Dublin, Cork, Galway and along the main roads; the far west and the islands can be thinner.
- Visiting Belfast or London on the same trip? A regional Europe plan covers Ireland and the UK together.
- A Leap card covers Dublin transport; most bookings and tickets are app-first.
How to get connected
- Download Num and pick Ireland.
- Choose a plan and pay with Apple Pay.
- Scan the QR code the app gives you — Settings → Cellular → Add eSIM.
- Turn on data roaming for the Num line when you land.
Questions about Ireland
How much does an eSIM for Ireland cost?
Plans start at $3.28. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Ireland eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
Is there an unlimited data eSIM for Ireland?
Num does not sell unlimited plans for Ireland. The closest are the daily-allowance plans, such as 500 MB per day, which give a fixed amount each day for the length of the trip. For most travellers the fixed bundles, from 500 MB to 100 GB, are better value.
Which networks does a Num Ireland eSIM use?
It connects to 3, Eir and Vodafone and picks the strongest available network automatically. Every plan on this page supports 5G where the network offers it.
Do I get a Ireland phone number with the eSIM?
No. Num eSIMs are data-only. Your own number stays active on your existing SIM for calls and texts, and WhatsApp, iMessage and other messaging apps keep working over the eSIM's data. If you need a local number, see our guide to eSIMs with a phone number.
What is the best eSIM for Ireland?
It depends on how long you stay and how much you use maps and video. On this page the best value per gigabyte is 5 GB per day for 1 day at $4.20 ($0.84); the trip-length picks match a plan to a weekend, a week, two weeks and a month.
