Budapest eSIM
100 Hungary plans · from $2.33
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.

How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.
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.
