If you want mobile data in Kraków, you have three realistic routes: a prepaid Polish SIM bought in town, an eSIM installed before you fly, or your home plan on roaming. Which one wins depends on where you live. UK travellers can no longer assume free roaming in Poland, while EU residents usually can. A physical Polish SIM must be registered with your passport, so plan on a shop counter rather than a vending machine.
This guide walks through each option in the order you will meet it: before you leave, at the airport, and in the Old Town. It also covers networks, registration, top-ups and the downsides of eSIMs.
TL;DR
- UK and other non-EU visitors: check your operator's roaming terms before you fly. Free roaming in the EU is not guaranteed for UK plans.
- EU visitors: your home plan usually works in Poland at domestic rates, subject to fair use.
- Physical Polish SIM: buy it from a shop or kiosk, bring your passport, and let the assistant register and activate it.
- eSIM: the easiest way to land already online, but you need an unlocked, compatible phone.
- Four networks matter: Orange, Play, T-Mobile and Plus all cover Kraków well.

Which option suits your trip
A short city break and a week-long stay do not need the same answer. Start with these questions:
- Where is your home plan from? The EU rules on roaming apply to people whose plan is with an EU operator. Your Europe, the EU's official citizen portal, says that travelling to another EU country brings no additional charges, with calls, texts and data billed at domestic rates. It also notes that this applies as long as you spend more time at home than abroad, or use your phone more at home. That is the fair use point to check on a long stay.
- Do you need a Polish number? A local SIM gives you one, which is useful for restaurant bookings, taxi apps or a delivery. An eSIM or roaming does not, unless the eSIM product includes one.
- Is your phone unlocked and eSIM-ready? If not, the physical SIM is simpler.
- How much data will you actually use? Maps, translation and ticket apps use little. Streaming and video calls use a lot.
For many weekend visitors, roaming or a travel eSIM is enough. For a stay of a week or more, a local prepaid SIM tends to be the more flexible choice, and you can top it up as you go.
UK visitors: do not assume free roaming
Since the end of the Brexit transition period on 1 January 2021, UK mobile operators have had no obligation to guarantee surcharge-free roaming across the EEA, according to the House of Commons Library. The same briefing notes that the daily cap on roaming costs expired on 30 June 2022, and tells travellers to check their operator's roaming policy before going abroad.
In practice this means some UK plans include Poland in a roaming allowance, some charge a daily fee, and some charge by the megabyte. Look at your operator's roaming page or app before you board, and switch off data roaming if you are unsure. Travellers from the US, Australia, Israel, Norway and elsewhere outside the EU should do the same: your home plan's terms, not EU law, decide what you pay.
If your plan does roam cheaply, you may not need anything else. If it does not, one of the two local routes below will almost certainly serve you better.
Buying a Polish SIM card in Kraków
The four networks
Poland has four main mobile networks: Orange, Play, T-Mobile and Plus. Kraków guides describe all four as offering prepaid SIM cards, and coverage in the city centre is strong on each. T-Mobile Poland's own guide for tourists also lists Orange, Play, Plus and T-Mobile as the operators that sell tourist SIMs and eSIMs. Smaller brands such as Lycamobile and Mobile Vikings run on these same networks.
For a few days in the Old Town, any of the four will do. Coverage inside a 15th-century building can vary with wall thickness, but in a compact city centre you will not struggle to get signal on the street, in the Market Square or around Kazimierz.
Where to buy
You do not need a specialist shop. Typical places include:
- Newsagent kiosks. Relay and Inmedio kiosks sell starter packs from the main operators.
- Operator shops. Orange, Play, Plus and T-Mobile all have stores in the city, including on and around Floriańska Street.
- Shopping centres. Galeria Krakowska, at ul. Pawia 5 beside the main railway station, lists Orange, Play, Plus and T-Mobile among its stores. It is a convenient first stop if you arrive by train.
- Electronics stores. Larger chains in the same mall sell starter packs too.
Starter packs are cheap. The Kraków retailer ROCH lists starter packs for Orange, T-Mobile and Simplus Mini at 5 zł, alongside Play products. The starter is only the SIM itself. You then add a data package, which the shop assistant can do for you at the counter.
Buying at Kraków Airport
The airport is a mixed answer. The official Kraków Airport services page lists chargers and passenger telephones, but not a dedicated SIM shop. Local guides say the airport has no mobile phone shops as such, but that the Relay store near the check-in hall stocks starter packs from all four main providers.
So a SIM at the airport is possible, but it is a convenience purchase. If you arrive tired and want to keep things simple, this is fine. If you would rather compare packages, wait until you are in town, or arrive with an eSIM already installed. Stock and opening hours change, so do not plan your whole arrival around one kiosk.
If you are heading to the Old Town afterwards, our guide to which pick-up point to use for an Uber is worth reading before you order a ride, as you will need data for that too.
Registration: bring your passport
Poland requires prepaid SIM cards to be registered to a named user. The Polish telecoms regulator's consumer guide, Masz prawo!, says registration needs your name and surname plus your PESEL number or identity-document details. If you have no PESEL, which applies to nearly all short-stay visitors, you give your passport or residence-card details.
The regulator explained at the time that the rule is meant to make the country's anti-terrorism system more effective, and it recommends checking registration details with your chosen operator.
In plain terms:
- Take your passport, not a photocopy, to the counter.
- Tell the assistant which network you want and roughly how long you are staying.
- They register the SIM and activate it, and you usually leave with a working connection.
- Keep your old SIM safe, as you will need it again for your home number.
If you have a dual-SIM phone, you can keep your UK or home SIM active for incoming messages, such as bank codes, while using the Polish one for data.
Top-ups and what you pay
Prepaid plans in Poland usually work as a base starter plus data bundles that last a set number of days. Bundle sizes and prices change often, so read the current offer on the operator's own site or at the counter rather than relying on an old blog post. Ask three things before paying:
- How many gigabytes are included, and for how many days?
- What happens when the data runs out: does speed drop, or does it stop?
- Does the bundle work for hotspot sharing and for roaming elsewhere in the EU?
Top-ups can be done in the operator's app or at convenience stores. One practical point from T-Mobile Poland: check whether online top-ups accept a card issued abroad, because not every payment page does. Topping up in cash at a shop avoids the problem.
eSIM for Poland: easy, with a few conditions
An eSIM is a digital SIM stored in your phone. You install it by scanning a QR code, then switch on the line in your cellular settings. T-Mobile Poland says tourists can get an eSIM online or from operators, and that all four main operators offer eSIM.
Why people choose it
- You land already online, with no queue and no passport at a counter.
- You can install it at home on Wi-Fi the day before.
- Your physical SIM stays in the phone, so you keep your home number reachable.
Disadvantages to weigh
- Compatibility. Your phone must support eSIM and be network-unlocked. Check this before you pay, as a locked handset will refuse the profile.
- One-off setup. Some eSIMs can be installed only once. If you delete the profile or reset the phone, you may lose it.
- Identity checks. Some Polish operator eSIMs still ask for passport verification, online or in a shop. International travel eSIM brands usually skip this, though they are not Polish operators.
- Validity and terms. Check the number of days, how EU roaming is treated, and whether you can top up with a foreign card.
- Support. If something fails, you will need to fix it by email or chat, not at a counter.
In short, an eSIM trades a little control for a lot of convenience. For a short break with a recent iPhone or Android handset, that is often a good trade. For an older or locked phone, buy a physical SIM instead.
Wi-Fi, messaging and offline basics
You can lean on Wi-Fi in Kraków more than in many cities. Most cafés, restaurants and accommodation offer it, and the Old Town is compact enough that you are never far from one. Public networks are fine for browsing, but avoid logging in to banking apps on them. Use mobile data for those.
A few habits cut your data use whatever option you choose:
- Download an offline Kraków map before you leave your accommodation.
- Save your tickets and booking confirmations as screenshots or PDFs.
- Use Wi-Fi for large updates and photo backups.
- Keep a translation app with the Polish language pack downloaded. Our list of Polish travel phrases also includes the emergency number 112.
If you will be buying public transport tickets by app, you will want a working data connection on day one. Our guide to Kraków public transport tickets explains the options and how to avoid a fine.
A simple arrival plan
Here is a sequence that works for most first-time visitors:
- Before you fly: check roaming terms with your operator. Decide between roaming, eSIM and a local SIM. Make sure your phone is unlocked if you want an eSIM.
- On the plane: download offline maps and put your accommodation address in your notes.
- At arrival: if you installed an eSIM, switch it on. If you want a physical SIM and the airport kiosk has stock, buy there. Otherwise leave it for the city.
- In town: visit an operator shop or a kiosk with your passport and activate a data bundle sized to your stay.
- During the stay: top up through the operator app or a shop if you run low.
If you plan day trips, remember that coverage is good on main routes, but a mountain destination can be patchy. Our piece on the train from Kraków to Zakopane is a good reason to download maps in advance.
Where we fit in
Our boutique apartments sit in a 15th-century townhouse, 100 m from Kraków's Main Square, so everything above can be sorted on foot within minutes of arriving: operator shops and kiosks are a short walk away, and our apartments have free Wi-Fi for setting up an eSIM or downloading maps on your first evening. Each apartment has air conditioning, a kitchen area and a private bathroom, and we can arrange transfers from Kraków-Balice airport and from Kraków Główny station, so you reach us without needing a data connection to find your way.
See the apartment types and availability on the Bracka 6 website.
Our view: sort the connection, then forget about it
We host guests from the UK, the US, Spain, Norway, Germany, the Benelux countries, Australia and Israel, and the question of mobile data comes up in nearly every pre-arrival message. Our advice is the same each time: decide before you fly, not at the airport.
If your home plan covers Poland, use it and keep things simple. If not, an eSIM installed over our Wi-Fi on the first evening is the least stressful route for short stays, provided your phone is unlocked. For longer visits, or if you want a Polish number for bookings and deliveries, take your passport to a shop in the Old Town and ask for a prepaid pack. It is a ten-minute job.
What matters most is not the exact bundle, but having maps, tickets and your accommodation details available offline in case the signal drops. If you are staying in an apartment with a kitchen area, that also helps you plan meals; our guide to self-catering in Kraków covers this, and our one-day walking route is easy to follow with an offline map.

FAQ
Can I buy a SIM card at Kraków Airport?
Sometimes. The airport has no dedicated phone shops, but local guides say the Relay store near the check-in hall stocks starter packs from the four main networks. Stock varies, so it is wise to have a fallback, such as an eSIM or a shop in the city centre.
Do I need my passport to buy a SIM card in Poland?
Yes. Prepaid SIMs must be registered, and without a PESEL number you give passport or residence-card details, according to the UKE consumer guide. The shop assistant normally handles the registration and activation for you.
Is an eSIM or a physical SIM better for a short trip?
An eSIM is easier if your phone is unlocked and compatible, because you can set it up before you land. A physical SIM suits older phones and visitors who want a Polish number. Either way, check the validity period and the terms before paying.
Will my UK phone plan work in Poland?
It may, but it is not guaranteed. UK operators have not been obliged to offer surcharge-free roaming in the EEA since 1 January 2021, so check your operator's roaming terms and any daily charge before you travel.
Does EU roaming apply to my plan in Poland?
If your plan is from an EU operator, you should pay domestic rates for calls, texts and data in Poland, according to Your Europe. Fair use applies, so a long stay may need a closer look at your provider's terms.
