Ireland travel data eSIM
What is an Ireland eSIM?
An Ireland eSIM gives you instant data access the moment you step onto the island, whether you’re exploring Dublin’s historic streets, driving the Wild Atlantic Way, or hopping on a train to Galway. Install the profile before you leave, keep your home SIM for calls, and let the eSIM handle all your online needs while you discover Ireland’s landscapes and culture.
In Ireland the eSIM connects to Eir 5G’s network, so your data usage is measured by the plan you chose. The plan’s validity begins when you first make a data connection on the island, and the allocated gigabytes are available for the duration specified, whether you’re navigating city streets or rural routes.

Which networks you connect to in Ireland
When you activate the eSIM in Ireland it links to Eir 5G’s infrastructure. The actual reach of the service depends on Eir’s network deployment in the area you are visiting, so you’ll have data wherever the operator’s towers are present.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator does the Ireland eSIM use and what does that mean for a traveller?
The eSIM connects to Eir 5G’s network. For travellers this means your data will be routed through Eir’s infrastructure, and you can use any app that requires internet as long as you are within the operator’s service area.
Can the Ireland eSIM be used in a neighbouring country like the United Kingdom?
No, it is a single‑country plan valid only in Ireland. Separate regional or multi‑country plans are available for trips that also include nearby nations.
Which plan size suits a trip to Dublin and Galway?
As a rough guide, the 5 GB 30‑day plan often covers moderate usage for two major cities, while the 10 GB option provides extra allowance for streaming or frequent navigation.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
