Plan for your trip: Poland · Data for your trip — See plans →
The easiest way to get mobile data in Poland as a traveler is a travel eSIM installed at home; the alternative is a local SIM, which must be registered with an ID document. In Warsaw, Kraków, Gdańsk and Wrocław the network is reliable, while the weak spots are the Tatra Mountains, forested areas and parts of the coast. Poland is in the EU, so it’s easy to combine with Germany and Czechia on one regional plan, as long as every country is on the plan’s list.
How does mobile data work in Warsaw and Kraków?
Mobile coverage in Warsaw includes the center, the residential districts, the metro and Warsaw Chopin Airport. Poland’s major carriers, Orange, Play, Plus and T-Mobile, are building out 4G and 5G networks, and a travel eSIM connects to one of them as a partner network. Which network you get depends on the plan and your phone model.
Kraków, Gdańsk, Wrocław and Poznań also have solid coverage in the center and suburbs. Slowdowns happen on Kraków’s Main Market Square in peak season and at stadiums and concerts, when the network is simply overloaded. In historic centers with thick walls, cellar restaurants and the Wieliczka Salt Mine, the signal indoors can be weak or disappear.
Mobile data comes in handy all the time in Poland: city transit and train tickets are easiest to buy in apps, taxis and e-scooters are booked online, and Polish menus and signs aren’t always easy to decode without a translator app. Plenty of cafés and malls have free Wi-Fi, but out on the street and on the road you need mobile data.
Where is coverage weaker in Poland: the Tatras, the lakes, the coast
Outside the big cities, mobile data in Poland works along highways and in villages, but it can be patchy in the mountains, forests and lake country. You’ll notice it most in the Tatra and Bieszczady mountains, in the Masurian Lake District and in Białowieża Forest in the east of the country.

Local SIM card or eSIM in Poland?
For a short trip to Poland a travel eSIM is easier, while a local SIM makes sense for a long stay, study or work. As of October 2026, prepaid SIM cards in Poland must be registered with an ID document: the rule has been in place since July 2016, and an unregistered card won’t work. For a foreigner the simplest route is to register with a passport in a carrier store, since online registration with Polish carriers is usually built around Polish IDs. The process differs by carrier, so check it before your trip.
A travel eSIM skips local registration entirely. With MoreSim you buy on the website or in the @moresim_bot Telegram bot, pay with Telegram Stars from any country, right in the bot (bank card and SBP payments currently work with cards issued in Russia), and the QR code arrives in the chat in about 30 seconds. The eSIM works as a second line, and your home SIM stays in the phone. MoreSim plans are data-only, with no phone number. You can call over messaging apps where they aren’t restricted, and bank texts keep arriving on your home SIM.
- Check that your phone supports eSIM; the bot runs an automatic compatibility check.
- Buy a plan for Poland or the region and install the eSIM at home over Wi-Fi.
- After landing or crossing the border, choose the eSIM for mobile data.
- Turn on data roaming on the eSIM line: most travel eSIMs connect to the local carrier as a roaming partner. Turn off mobile data on your home SIM so your data doesn’t go through your home carrier.
- If there’s no network, toggle airplane mode or pick a network manually.
Is Poland included in a Europe eSIM plan?
Yes, as of October 2026 Poland is part of MoreSim’s Europe plan, as are its neighbors Germany, Czechia and Austria. A regional plan’s country list changes, so check it in the plan details in the catalog or in the bot before you buy. Check every country on your route, especially if you’re heading further east or to the Balkans.
The EU’s “roam like at home” rule applies to SIM cards from EU carriers: a Polish local SIM usually works in Germany or Czechia on home terms, subject to fair-use limits, so check the details with the carrier. The rule doesn’t cover countries outside the EU.
Is there coverage on trains from Poland to Germany, Czechia and Austria?
On trains from Poland to its neighbors there’s generally coverage along the main lines, and after the border your phone switches to the neighboring country’s network, as long as your plan works there. Trains run from Warsaw and Poznań to Berlin, and from Kraków and Katowice to Prague and Vienna. Some stretches through forests and near the border have gaps.
| Route | Countries to check in your plan |
|---|---|
| Warsaw to Berlin | Poland, Germany |
| Kraków to Prague | Poland, Czechia |
| Kraków to Vienna | Poland, Czechia, Austria |
| Gdańsk and the Baltic coast | Poland |
If a country on your route isn’t in the plan, install a separate plan for it as a second eSIM at home, before you go. On the train, all you have to do is choose the right eSIM for mobile data after the border.
How much data do you need in Poland?
A city break in Warsaw or Kraków doesn’t need much data: maps, messaging, taxis, a translator and online tickets. Usage climbs with video, streaming and video calls, and in the mountains with photos and clips from the summits. If you’re working remotely from a laptop, budget considerably more.
- Download offline maps for the cities and mountain routes.
- Keep photo and video cloud uploads for Wi-Fi.
- Turn off app auto-updates over mobile data.
- If you run out of data, top up without a new eSIM: use “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan.
For a detailed breakdown, see “How much data do I need for travel”. If your eSIM won’t connect, MoreSim support is reachable via /support in the bot, a ticket in your account and email.
FAQ
How good is mobile internet in Poland for tourists?
In Warsaw, Kraków, Gdańsk, Wrocław and other big Polish cities, mobile data works reliably, including on the Warsaw Metro. Along highways and rail lines there’s generally coverage. Gaps show up in the mountains, in forested areas in the east of the country and on some stretches of the coast.
Do I need a passport to buy a SIM card in Poland?
Yes. As of October 2026, prepaid SIM cards in Poland must be registered with an ID document, and an unregistered card won’t work. For a foreigner the easiest way is to register with a passport in a carrier store, since online registration is usually built around Polish IDs. A travel eSIM is installed at home and needs no local registration.
Is there cell service in Zakopane and the Tatra Mountains?
In Zakopane and at the bottom stations of the cable cars, mobile data is usually available. On Tatra hiking trails, in the valleys and near the high mountain lakes, the signal is patchy and can drop out. Download the trail map offline, save the emergency number 112 and don’t rely on having signal on the route.
Is Poland included in a Europe eSIM plan?
Yes, as of October 2026 Poland is in MoreSim’s Europe plan along with Germany, Czechia and Austria. A regional plan’s country list changes, so before buying, check Poland and the other countries on your route in the Europe plan details in the MoreSim catalog or in the @moresim_bot bot.
How do I get mobile data in Poland after I arrive?
Install the eSIM at home over Wi-Fi. After you land or cross the border, turn off airplane mode, choose the eSIM for mobile data and turn on data roaming on it. The plan starts counting on its first connection to a network in your destination.
Which eSIM should I get for a trip to Poland and Germany?
A regional plan that covers both countries works, or two separate plans installed as two eSIMs. As of October 2026, MoreSim’s Europe plan includes both Poland and Germany, but check the list in the plan details before you buy. On the Warsaw to Berlin train, your phone will switch to a German network after the border.
