Budapest eSIM

100 Hungary plans · from $2.23

Budapest is two cities either side of a river, and half the confusion of a first visit is realising your hotel is in Pest and the thing you want to see is up a hill in Buda. A travel eSIM keeps maps and the BKK transit app working from arrival, including the airport bus that most visitors take in.

Landing at Ferenc Liszt (BUD)

The 100E airport bus runs direct to Deák Ferenc tér in about 40 minutes and requires a dedicated ticket — the standard transit pass is not valid on it. Buying in the BKK app on arrival avoids a fine.

Which networks you'll be on in Budapest

Siima eSIMs for Hungary ride Magyar Telekom and Yettel. Telekom has the widest 5G footprint across Budapest and the motorway network; Yettel is comparable in the city centre.

Coverage around Budapest

Metro lines M1 to M4

Coverage across all four lines. M4 is the newest and has the most consistent tunnel signal; M1, the 1896 line running just below street level, is fine throughout.

Pest centre and the ruin bars

Strong 5G across District VII and the centre. The ruin bars are indoors in old courtyard buildings where signal weakens, though rarely enough to matter.

Buda Castle and Gellért Hill

Both well covered, including the funicular and the hill paths. The elevated position actually gives some of the best signal in the city.

Szentendre and the Danube Bend

The HÉV suburban rail to Szentendre holds signal the whole way, and the riverside towns of the Danube Bend are covered.

How much data you need

A long weekend in Budapest is about 2–3 GB. Note that the thermal baths ask you to lock your phone away — you will use less data than you expect on bath days.

Frequently asked questions

Can I use my phone at the Széchenyi or Gellért baths?
Coverage is fine in and around the bath complexes, but phones go in a locker for most of the visit and the humidity is hard on them. Plan for a few disconnected hours rather than a data problem.
Does a Hungary eSIM cover a trip to Vienna or Bratislava?
No — a Hungary plan stops at the border. Vienna is under three hours by train and a very common add-on, so if you are combining them, a Europe regional plan covering Hungary, Austria and Slovakia on one eSIM is the simpler option.
How do I set up an eSIM before arriving in Budapest?
Install it at home while you still have Wi-Fi: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Leave the line switched off until you land — the plan starts counting from first use in Hungary, not from purchase.
How much data do I need for a trip to Budapest?
A long weekend in Budapest is about 2–3 GB. Note that the thermal baths ask you to lock your phone away — you will use less data than you expect on bath days.
Is an eSIM cheaper than roaming in Budapest?
Almost always. Daily roaming passes from most home carriers run $10–15 per day, while Siima plans covering Budapest start from $2.23 for the whole trip. You also avoid per-megabyte charges if you exceed a roaming pass allowance.
