From the Parliament and thermal baths of Budapest to summer on Lake Balaton and the wine regions of Tokaj and Eger, Hungary is full of highlights. You will use data for maps, public transport, Bolt, restaurant bookings and translation apps.
If your home carrier is outside the EU, roaming can be expensive, and local prepaid SIMs require ID registration. A Hungary eSIM is a simpler option: buy it online, install before you go and connect as soon as you land in Budapest. Simhop compares current Hungary plans below.
Networks and coverage in Hungary
Hungary has three mobile operators: Magyar Telekom, Yettel and One Hungary. Magyar Telekom is generally rated as having the best coverage, while Yettel and One are also reliable in cities and along main routes.
4G coverage is good across most of the country, and 5G is available in Budapest and other larger cities. Lake Balaton has strong coverage, though it can get congested on busy summer weekends. Some rural areas and hills may have weaker signal.
How much data do you need in Hungary?
For a city break in Budapest, 3 to 5 GB is usually enough. A summer week at Lake Balaton with streaming, social media and navigation is more comfortable with 5 to 10 GB. See How much data do I need? for a breakdown.
