Mobile data in Hungary: Budapest, Balaton and the borders

Hungary is in the EU, so a European plan works at home prices. What is worth knowing is what happens at its edges: Serbia to the south is outside the EU roaming area, while Ukraine to the east joined it in 2026.

Is roaming free in Hungary?

  • Plans from the EU and the EEA: yes, roam like at home applies, within your operator’s fair use limit.
  • UK plans: it depends on your operator since Brexit.
  • Plans from outside Europe: usually international roaming or a daily pass.

The EU roaming calculator tells you the minimum for your plan.

Will it work on my phone?

On iPhone: Settings → General → About, and scroll to EID. If there is an EID, your phone takes eSIMs. Every iPhone from the XS (2018) onwards does.

On Android: Settings → About phone → Status, and look for EID. If there is an EID, your phone takes eSIMs. Most Galaxy S20, Pixel 3 and later do.

It also has to be carrier-unlocked. If you bought it outright or your contract is over, it almost certainly is.

And if it turns out yours cannot use it, write to us and you get every cent back.

The borders: Serbia out, Ukraine in

Hungary borders seven countries. Austria, Slovakia, Slovenia, Croatia and Romania are all in the EU, so nothing changes. Serbia is not, and it has its own regional roaming arrangement rather than the EU one, so your operator charges its own price there. Ukraine joined the EU roam-like-at-home area on 1 January 2026, so the eastern border no longer takes you out of the rule.

Which eSIM works in Hungary?

A Hungary eSIM runs on the local networks, Telenor Hungary (5G), Vodafone (5G). Data only: your usual number stays on your own SIM.

Coverage: Budapest, Balaton and the plains

Budapest has strong coverage with 5G, including most of the metro, and so do Debrecen, Szeged and the motorways. Around Lake Balaton it is good in the towns and thinner on the water. On the plains and in the small villages it varies, but the country is flat and well covered by European standards.

How much data for a trip to Hungary?

  • 3 GB: a long weekend in Budapest.
  • 5 GB: a week with maps, messages and photos.
  • 10 GB: two weeks, or a summer at Balaton with video calls.
  • 20 GB: a month, or sharing data with a laptop.

The data calculator gives an estimate in five questions.

Prices for Hungary

Hungary data eSIMs: 3 GB for 4,49 €, 5 GB for 6,79 €, 10 GB for 11,29 € and 20 GB for 16,99 €. The plan starts on the first connection in Hungary.

Questions
Is roaming free in Hungary with an EU plan?

Yes. Hungary is in the EU, so roam like at home applies, possibly with a fair use data limit.

What happens if I cross into Serbia?

Serbia is outside the EU roaming area, so your operator charges its own tariff. Check it before crossing.

And into Ukraine?

Since 1 January 2026 Ukraine is in the EU roam-like-at-home area, so an EU plan works there at home prices.

Is there signal on the Budapest metro?

On most of it, yes. Deep sections can drop briefly, as in any underground network.

Get your eSIM before you fly: the QR arrives by email in minutes and the plan only starts when you connect at your destination.

Who is behind this

A person, not a call centre

Snoozim is run from Barcelona by Ibai Guirado Vera. It exists because paying for roaming by the day on a short trip made no sense. If something goes wrong with your eSIM you write, and the same person who built this answers you, within 24 hours.
