Using an eSIM in Budapest

Two banks with two personalities: open sky on the Buda hills, an easy grid over in Pest.

公開: 2026年9月21日最終更新: 2026年9月21日

Liszt Ferenc Airport (BUD), terminals 2A and 2B, sits a fair way out and still has no rail link, so it is the 100E express bus to Deák Ferenc tér or the 200E out to the M3 metro. Others come in by international train from Vienna and Bratislava into Keleti or Nyugati, or by coach into Népliget. Switch the line on inside the terminal before you walk to the stand: city tickets can be bought in the app and the machine queues are often long. The ride in holds signal except on the deeper platforms.

Budapest

What Budapest is like on a phone

Budapest takes several crowds at once: bathers, a night-out crowd doing the ruin bars, and families on the Danube boats. The city is larger than people expect and most movement happens on the metro and the trams, so the phone comes out constantly. On the Pest grid the map behaves itself; over on the Buda side the fix is accurate enough but the route the app picks has a habit of sending you up a very long flight of steps.

電波が変わる場所

Over in Pest, with its wide boulevards and continuous building lines, things stay steady across whole districts. On the Buda side the castle hill and Gellért hill look out over everything and feel open, while the roads winding between the hills have short dead patches. The very shallow M1 line usually works the whole way, unlike M2 and M4, which dive under the river and go quiet for minutes at a time. Inside the domed bath halls and the caves under Buda, assume nothing from the start.

What a day here costs in data

A normal day here lands around 800MB to 1.8GB, mostly the city transport app, maps and translating Hungarian menus, which you cannot guess your way through from any other language. Bath sessions and boat tickets are booked on the phone as well. If you are out in the bar district shooting long video to send home each night, about 2.5GB a day is the comfortable figure.

Districts travellers ask about

  • District V, BelvárosThe riverside core of Pest, walking distance to parliament and the Chain Bridge; the wide streets keep the map steady and make it the easiest place in town to meet someone.
  • District VII, ErzsébetvárosRuin-bar country, heaving after eight; the layered courtyards of the old blocks make the speed you feel drop noticeably on a weekend night.
  • District I, the Buda Castle hillHigh and open, so it is the easiest part of Buda to use a phone in — but the ways up include a funicular and some very long staircases, so look at which one the app has chosen for you.
  • District XIII, ÚjlipótvárosA residential river strip north of parliament: quiet, full of cafés, and the district long-stayers pick because it stays steady all day.

Day trips out of the city

  • SzentendreForty minutes on the H5 suburban line from Batthyány tér, connected nearly the whole way because it never leaves the suburbs; the little old-town lanes stutter the way old-town lanes do.
  • The Danube Bend: Visegrád and EsztergomThe riverside road under the cliffs thins out in places, while the citadel above Visegrád is wide open because of the height. If you go by boat, sailings shift with the season and from year to year, so check the operator's own timetable before you build a day around it.
  • EgerTwo hours by car or coach on well-covered motorway, but the wine cellars cut into the Szépasszonyvölgy valley have nothing at all — save your return address and the last bus time on the phone before you go down the steps.

Getting online in Budapest

Which metro lines keep working and which go dead?+

Broadly, the shallowest line, M1, tends to work the whole way, while the deep lines that pass under the river go quiet for minutes at a time. The practical habit is to check your route and screenshot the interchange before you go down, then answer messages when you surface.

Can I take my phone into the thermal baths?+

Most have lockers, and carrying one into the water halls is a bad idea anyway because of the steam and humidity. Even if you do, the thick domed masonry leaves you with almost nothing. It is simpler to lock it away and agree a meeting time with your friends in advance.

What is the signal like on an evening Danube cruise?+

The boats stay in the middle of the city between the bridges, so you are within reach of land networks and it mostly behaves. What you will notice are short stumbles passing under the bridges and where the boat hugs a high bank. If you plan to go live when the parliament lights come on, expect the picture to hiccup at the bridges.

I want to drive into Slovakia or Austria for the day. What should I sort out first?+

Check whether what you are carrying lists the country you are crossing into — read the covered-destination list rather than assuming the word Europe settles it. Entry requirements, including the EU's entry and exit arrangements, are adjusted from time to time, so confirm them against official announcements before each trip.
