Mobile data in Poland: Warsaw, Kraków and the mountains

Poland is in the EU and its mobile networks are fast and cheap by European standards. For most visitors roaming is already covered; the parts worth reading are the mountains, the countryside and the eastern borders.

Is roaming free in Poland?

  • 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 shows the minimum your plan has to give you.

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 eastern border: what changed in 2026

Ukraine and Moldova joined the EU roam-like-at-home area on 1 January 2026, so crossing from Poland into Ukraine no longer drops you out of the rule. Belarus and Russia are a different matter and stay outside it entirely. Near any of those borders your phone can pick up the network on the other side, so choose it by hand if you are close.

Which eSIM works in Poland?

A Poland eSIM runs on the local networks, Play (5G), Orange (4G). Data only: your usual number stays where it is.

Coverage: cities, the Tatras and the lakes

Warsaw, Kraków, Gdańsk and Wrocław have strong coverage with 5G, and the motorways are well served. In the Tatra mountains, the Bieszczady and around the Masurian lakes it thins out, and on high trails it can disappear. Download maps before a hike.

How much data for a trip to Poland?

  • 3 GB: a long weekend in Kraków or Warsaw.
  • 5 GB: a week with maps, messages and photos.
  • 10 GB: two weeks, or a road trip with video calls.
  • 20 GB: a month, or sharing data with a laptop.

The data calculator gives an estimate in five questions.

Prices for Poland

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

Questions
Is roaming free in Poland with an EU plan?

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

Does my plan work if I cross into Ukraine?

Since 1 January 2026, yes: Ukraine joined the EU roam-like-at-home area. Belarus and Russia remain outside it.

Is there signal in the Tatra mountains?

In the valleys and the resorts, usually. On high trails it can vanish on any network, so download offline maps.

Do I need ID for a data eSIM?

No. A data eSIM bought online needs only an email address; a local prepaid SIM is registered with ID.

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.
