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.

Two simple ways to buy

Dublin eSIM plans: unlimited, or by the GB.

Every Dublin eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Dublin — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

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 $2.15/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.

Peace of mind

Your Dublin eSIM: data-only, zero bill shock.

Your Dublin eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Dublin, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
