Does the eSIM work on a black-taxi mural tour of West Belfast?

Yes. The Falls Road, Shankill Road and the rest of West Belfast have solid mobile coverage, so you can read up on the murals, drop pins and share photos throughout the tour. Your driver-guide's route stays fully mapped from start to finish.

Can I use this eSIM in the Republic of Ireland too?

No - this is a national UK eSIM, so it covers Belfast and all of Northern Ireland but not the Republic of Ireland. If you cross to Dublin or the coast you'd need a separate plan, and note your phone may pick up Irish networks near the border.

Good to know in Belfast

If you head south toward the Irish border for a day trip, your phone can automatically latch onto a Republic of Ireland network. This UK eSIM won't work there, so keep an eye on which network your phone shows near the frontier.

Two simple ways to buy

Belfast eSIM plans: unlimited, or by the GB.

Every Belfast eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Belfast — 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.

Best value for lighter, shorter trips

How much data do you need in Belfast?

A rough, honest guide to sizing your Belfast eSIM so you're not guessing. Most travellers in Belfast are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Belfast eSIM: your local data guide.

Belfast tells its story through shipyards, murals and a lively music scene, and data helps you piece it together. A Belfast eSIM keeps maps live for a black-taxi mural tour, books your Titanic Belfast slot, and pulls up gig listings and reviews across the buzzing Cathedral Quarter.

One eSIM for Belfast and all of United Kingdom. It's the national United Kingdom eSIM — from $2.15/day with unlimited data, working the same in Belfast as it does the moment you leave it.

Landing at Belfast International Airport (BFS)?

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 Belfast eSIM: data-only, zero bill shock.

Your Belfast eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Belfast, 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.

Belfast eSIM questions, answered.

Both. Belfast has two airports - Belfast International (BFS) and the more central George Best Belfast City (BHD) - and your eSIM connects at either one. It runs on the UK's major networks, so you'll have data for a taxi or the Airport Express bus straight away.
