Does it work on the metro and in the thermal baths?

Above ground and across all four metro lines coverage is strong, though signal can dip in the deepest M2, M3 and M4 tunnels. Inside Széchenyi or Gellért baths you will usually get data in the outdoor pools but less in the interior chambers.

Can I use the same eSIM for a day trip outside Budapest?

Yes. This is a single national Hungary plan, so the same eSIM keeps working on a day trip to Szentendre, the Danube Bend, Gödöllő or anywhere else in the country. One allowance covers your whole Hungarian trip.

Good to know in Budapest

Budapest's public transport is excellent and the BudapestGO app sells QR tickets you scan on board, so top up on your eSIM data before you hop on tram 4/6 or the M1 millennium metro.

Two simple ways to buy

Budapest eSIM plans: unlimited, or by the GB.

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

How much data do you need in Budapest?

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

Budapest eSIM: your local data guide.

Split by the Danube into hilly Buda and buzzing Pest, Budapest keeps you reaching for your phone - queuing for the Széchenyi thermal baths, booking a Danube cruise, hunting down a ruin bar in the Jewish Quarter or riding tram 4/6 after midnight. A Budapest eSIM has maps, Bolt and BudapestGO live the moment you land, so you never rely on café Wi-Fi.

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

Landing at Budapest Ferenc Liszt International Airport (BUD)?

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

On the ground

Where you'll lean on data in Budapest.

Castle Hill (Buda Castle District)

Pull up funicular times, Fisherman's Bastion opening hours and photo spots while you wander the cobbled Castle District.

District VII - Jewish Quarter

Find the next ruin bar, book a Szimpla Kert table and split the bill by app as you crawl the backstreets.

City Park (Városliget)

Reserve a Széchenyi Baths cabin, check Heroes' Square and the zoo, and navigate the park's wide paths without losing signal.

Central Pest (Parliament & the Basilica)

Book a timed Parliament tour, pin St Stephen's Basilica and hail a Bolt along the Danube promenade.

The practical bit

Getting around Budapest on your eSIM.

Apps you'll want online in Budapest

BudapestGO— Official BKK app for QR transit tickets and metro, tram and bus routes.
Bolt— Budapest's go-to ride-hailing app; live driver tracking needs steady data.
Főtaxi— The city's official taxi fleet; book and pay from your phone.
MOL Bubi— Budapest's public bike-share; unlock docked bikes and track rides in-app.

How long to stay in Budapest

Most visitors spend three to four days here, enough for both castle hills, the thermal baths, a Danube cruise, the Jewish Quarter and a Parliament tour.

How much data for Budapest

For a city break of maps, Bolt rides, ticket QR codes and social posts, 3-5 GB is comfortable; choose Unlimited if you plan to stream, video-call home or hotspot a laptop from your hotel.

Coverage in Budapest

Magyar Telekom, Yettel and One Hungary all give strong 4G and growing 5G across Buda and Pest; the only real dead spots are the deep metro tunnels and some basement bars and baths.

Peace of mind

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

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