Poland is a large country that most visitors see in two or three cities, and those cities are thoroughly covered. It is cheap to buy data for, the intercity trains are good and hold a signal, and the places where coverage actually falls away are the mountains in the south and the forests in the east.
Urban and intercity strong, Tatras and Białowieża thin
Kraków, Warsaw, Gdańsk, Wrocław and Poznań are densely covered, and the intercity rail corridors between them are reliable — the Warsaw–Kraków and Warsaw–Gdańsk routes hold a signal for effectively the whole journey.
The Tatra mountains in the south are where it stops. Zakopane and the valley floors are covered; the high trails, the ridges and the routes toward Rysy and Morskie Oko are patchy to absent. Polish mountain weather turns fast and the trails are serious, so that gap is worth respecting rather than working around.
The eastern border regions and the Białowieża forest are the other thin area — sparsely populated, heavily forested, and not somewhere to arrive without the map already downloaded.

Live prices in GBP, updated from our network partners. 6 plans currently available for Poland. Validity counts from the moment the eSIM first connects to a network in Poland, not from when you buy — so installing days before you fly costs you nothing.
£1.49 is the entry price rather than the best value. At £1.49 per gigabyte it is the most expensive data on the list; the 20 GB plan at £11.99 is £0.60 per gigabyte. If there is any realistic chance you will use more than 1 GB, the larger plan costs less than buying the small one twice.
Roaming, and whether you need this at all
Poland is in the EU, so EU and EEA SIMs roam at home rates. Poland uses the złoty rather than the euro. For non-EEA visitors, Poland sits at the lower end of European travel data prices, which the list below reflects.
Auschwitz, Wieliczka and timed entry
The major day trips out of Kraków run on timed, booked entry, and the booking and ticket presentation happen on a phone. That is the one place a Polish trip genuinely depends on having a working connection at a specific moment, and it is worth screenshotting the confirmation rather than relying on loading it at the gate.
Otherwise a Polish city trip is light on data. Transport apps, maps and messaging, with the entry plan comfortably sufficient for a few days.
The networks you actually connect to
In Poland our plans roam onto Play (5G), Orange (4G). That is worth stating plainly because it is the thing that determines your experience: a travel eSIM does not have its own masts, so your signal is whatever those operators have built, and 5G is available where they have deployed it and your handset supports it.
It also means no provider can sell you better coverage in Poland than the local networks have. Where there is a gap, it is a gap for everyone — local customers included.
Before you buy
Check the handset takes an eSIM and is not carrier-locked. Dial *#06# and look for an EID alongside the IMEI — no EID means no eSIM hardware whatever the model name suggests, and a locked phone will install the profile and then refuse to register. The device compatibility guide lists what works.
Then install before you fly, while you still have reliable Wi-Fi. Setup by brand: iPhone or Android. If it will not connect after you land, this works through the causes in order.
