You have just landed at Warsaw Chopin, your train into the city leaves soon, and your phone has popped up a cheery warning that roaming charges may apply. You could join the queue at an airport kiosk, fiddle with a paperclip on the concourse and hope the setup instructions make sense. Or you could have sorted your data before you left home, so your phone simply connects the moment you land.

Poland rewards a connected traveller more than most destinations. Trains are booked in apps, trams are paid for by phone, and a cash-free lunch at a market stall is completely normal. Here is the practical side of travelling in Poland, and how to keep your phone online for all of it.

Getting around Poland runs on your phone

Poland's intercity trains link Warsaw, Kraków, Gdańsk, Wrocław and Poznań, and they are the pleasant way to cover the distances between them. Many long-distance services have reserved seating, so buying tickets in the operator's app before you travel saves you a queue at the station and a scramble for a seat on busy routes.

In the cities, trams and buses do the heavy lifting. The journey planner apps locals use will tell you which tram to catch, where to change and when the next one actually arrives, and in most big cities you can buy your ticket in the same app. The catch is that everything happens before you board: mobile tickets need to be bought, and sometimes activated, while you are standing at the stop. That is precisely the moment you need working data rather than a hotel wifi network two streets behind you.

Ride-hailing apps are widely used in Polish cities and often simpler than flagging down a taxi, especially late in the evening. It is also worth downloading offline maps for the old towns, where narrow streets and courtyards can confuse GPS, but remember that live departure times, opening hours and reviews still need a connection.

Card, phone or złoty?

Poland uses the złoty rather than the euro, which surprises plenty of first-time visitors. What surprises them more is how little cash they need. Contactless payment is accepted almost everywhere: supermarkets, cafés, taxis, museums and a good share of market stalls. Locals pay for nearly everything by card or phone, and you can comfortably do the same, keeping a little cash aside for the odd small bakery or public toilet.

Data still matters here. Banking apps often want to send a push notification or an in-app approval when you make a larger payment abroad, and if your phone is offline that confirmation never arrives. A working connection also lets you check your own bank's rate before you commit to an ATM withdrawal, and politely decline the machine's offer to convert the charge for you.

Menus, milk bars and a language full of consonants

Polish is a wonderful language to listen to and a difficult one to guess. English is common in hotels and tourist-facing restaurants, but less so in the places that make Poland memorable: the neighbourhood pierogi spot, the corner bakery, the classic milk bars (bar mleczny) serving home-style cooking.

A translation app with camera mode makes those menus readable in seconds, and it earns its keep again on train announcements, museum labels and mystery jars in the supermarket. Live translation runs on data, so it is one of those quiet features that only works if your phone is properly online when you need it.

Mobile data in Poland with Keep On Roaming

Keep On Roaming connects to two mobile networks in Poland, Play and Orange Polska, with speeds up to 5G.

The Roam Like Home® plans are designed to be sorted before you fly. You install the eSIM once via QR code before you travel, and it activates when you arrive in Poland and connect. Plans are data-only, so your existing SIM keeps working alongside: your number stays live for calls and texts while the eSIM quietly handles the internet.

If you use more than expected, there is no need to start again. Existing eSIMs can be topped up with more data from your account dashboard, without installing a new eSIM.

How much data do you need in Poland?

It depends less on the length of your trip than on what your phone does all day. As a rough guide:

Light use (messaging, maps, the odd search): 1 GB over 7 days for £4.50 suits a careful city break, and 2 GB over 15 days for £6.50 fits a slower-paced trip.
Everyday use (navigation, transit apps, social media, photos backing up): 5 GB over 30 days for £10.00 or 10 GB over 30 days for £13.00 gives you comfortable headroom.
Short and intense (streaming, video calls, hotspotting a laptop): unlimited data plans run from 1 day at £6.50, through 3 days at £10.50 and 5 days at £13.00, up to 7 days at £14.50.
Longer stays and remote work: 20 GB for £16.00, 50 GB for £24.00 or 100 GB for £47.00, each lasting 30 days. Prefer not to count at all? Unlimited plans are available for 10 days at £16.00, 15 days at £18.50 or 30 days at £35.00.

If you are undecided, start smaller. Because top-ups are added to the eSIM you already have, choosing a modest plan first and adding data later is painless.

A few minutes of preparation buys a very smooth arrival: install your eSIM at home, land in Warsaw or Kraków, and watch your phone connect while everyone else is still queuing at a kiosk. Browse the full range of Poland plans and pick the size that fits your trip.
