Does it work on the Luas and DART?

It does. You'll have data across the tram and rail network for live departure times and mobile ticketing through the TFI Go app. Coverage can dip briefly in deeper cuttings, but service returns quickly as you move above ground.

How much data do I need for a Dublin city break?

For a long weekend of maps, messaging and social posts, most travellers are comfortable with 3-5GB. If you're streaming music on the DART or sharing lots of videos, consider a larger allowance to be safe.

Good to know in Dublin

Dublin's Luas trams and DART trains run on the TFI Leap Card, but the TFI Go app lets you buy tickets straight from your phone, so keep your eSIM data topped up for hop-on journeys across the city.

Does an eSIM work in Dublin?

Yes — the Ireland eSIM works in Dublin wherever its partner networks have signal. You'll find strong 5G across the city centre, Dublin Airport and along the DART and Luas lines, with dependable coverage citywide; signal can dip briefly inside the Port Tunnel and in some stone-walled basements and older pubs.

Your guide to Dublin

Dublin eSIM: your local data guide.

Dublin rewards the well-connected traveller. You'll want live maps threading the cobbles of Temple Bar, a timed ticket held for the Book of Kells at Trinity College, and a Free Now taxi summoned after a late pint near Grafton Street. A Dublin eSIM keeps you online the moment you land, so the Guinness Storehouse tour and DART timetables are always a tap away.

One eSIM for Dublin and all of Ireland. It's the national Ireland eSIM — from £1.32/day with unlimited data, working the same in Dublin as it does the moment you leave it.

Landing at Dublin Airport (DUB)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

The short version.

A travel eSIM is data only. It sits next to your home SIM, so your number, texts and WhatsApp carry on as normal. Pick unlimited, priced per day, or a fixed bundle of GB if it's mostly maps and messages. Install it on Wi-Fi before you fly — the days only start once it first connects in Dublin, and it finds a partner network on its own.

Before you fly

Dublin eSIM questions, answered.

Yes. Set up the eSIM before you fly and it connects automatically to an Irish network — usually Three Ireland, Vodafone or Eir — as soon as you switch off aeroplane mode at Dublin Airport, so you can order a taxi or bus straight away.
