A newcomer to Poland needs a registered prepaid SIM (oferta na karte) or a monthly contract, and a passport is enough for prepaid at all four networks. Registration is mandatory and an unregistered card is blocked after 30 days. Until the local plan is ready, a data only eSIM keeps you online for maps, email and internet calls.
Poland SIM card for international students: what you need
A valid passport is enough to buy and register a prepaid SIM in Poland, and you do not need a PESEL for that. Prepaid registration is mandatory: the provider checks your identity data against your ID document, and an unregistered card is blocked 30 days after purchase.
What to bring and expect:
- Main networks: Orange, Play, Plus and T-Mobile.
- Buy in operator shops, shopping centres, press kiosks, Zabka stores, petrol stations or the airport.
- Register in the shop where you buy, in the operator's app via mojeID, or by phone. Remote photo matching is allowed.
- Play accepts a residence card and does not need a Polish registered address.
- All four networks offer prepaid eSIM, but the prepaid registration rules still apply.
If you want data before you land, see the Poland plan page and check your handset with the eSIM compatibility guide.
Prepaid SIM or monthly contract: which comes first
Start with prepaid. A monthly contract usually needs a PESEL, and without one T-Mobile says you can only sign in a shop while Orange's online order form asks for a PESEL. Prepaid has no contract to sign and Play says it needs no PESEL and no Polish bank account.
Contract requirements to expect:
- PESEL for online sign-up.
- Passport or residence card number if you have no PESEL.
- A residence document valid for the contract term (Orange asks for validity at least one month past the end of the contract).
- Plus asks non-EU, non-Swiss customers for a passport or residence card number.
Once your PESEL and residence document are in place, a contract becomes straightforward. Until then, prepaid is the practical route, and a data eSIM covers the gap. Read more on moving abroad.
How long the paperwork takes
Address registration is the first deadline: non-EU citizens must register within 4 days of moving in, and EU, EFTA and Swiss citizens within 30 days. PESEL is assigned automatically when you register residence for over 30 days; otherwise you apply in person at any municipal office, free, and are notified once the number is assigned.
What is and is not known:
- PESEL application is accepted on the spot, but the exact processing time is not confirmed, so confirm with the office.
- A Polish bank account: document rules vary by bank, some require a PESEL for some services and others do not. Time to open is not confirmed, so ask the bank.
- For visa or residence questions, check the official source for your nationality rather than relying on a guide.
Registering your address is also the easiest way to get a PESEL, so do it early.
Your first 30 days in Poland: a timeline
The first month is mostly about registration. Get your address registered within 4 days if you are a non-EU citizen, buy and register a prepaid SIM in your first days, and keep your home SIM active for bank codes until a Polish number is set up.
A practical order:
- Days 1 to 4: register your address (non-EU) and buy a prepaid SIM, registering it in the shop.
- Week 1: install a data eSIM if you need internet before the local card is active, and keep your home SIM for SMS codes.
- Weeks 2 to 4: apply for PESEL if it was not assigned automatically, then look at a bank account.
- After PESEL: consider a monthly contract in a shop or online.
Remember the 30 day block on unregistered prepaid cards.
Staying connected until your local plan is ready
A data only eSIM covers the gap. Slashtel eSIMs have no local phone number and no calls or SMS, but WhatsApp and other internet calls work over the data. Options run from 1 GB to 20 GB, and the 5 GB plan starts from $5.89.
How it works:
- Buy online with an email address and a card, Apple Pay or Google Pay; the QR code arrives by email within minutes.
- Validity starts when the eSIM first connects in Poland, so you can buy and install it at home before the flight.
- The network is chosen automatically and cannot be picked by hand.
- More data can be added to the same eSIM later, with no new QR code.
- Your phone must be unlocked and eSIM compatible.
See installation steps and estimate your usage with the data calculator.
Getting a local number for your bank and admin
A Polish number is needed once you deal with banks and admin that send codes by SMS or call you back. A prepaid local SIM gives you that number; the Slashtel eSIM does not, because it is data only.
Plan for it:
- Buy a prepaid SIM from Orange, Play, Plus or T-Mobile and register it with your passport.
- Keep the number active while you open a Poland bank account and register your address.
- Keep your home SIM in the phone for codes from your home bank, with data roaming turned off to avoid charges.
- If a service insists on a PESEL, ask the bank or office which documents they accept.
This is why many newcomers run a local prepaid card and a data eSIM side by side in the first weeks.
When family visits you in Poland
Visiting family can use a Slashtel eSIM for the trip. The person living in Poland can buy it and enter the visitor's email, so the QR code goes straight to the person who will use it.
Good to know:
- A sim card for parents visiting Poland is simpler as data only: they keep their home number for calls and use internet calls over data.
- Choose a data size that matches the length of stay, from 1 GB to 20 GB.
- Install before arrival, since validity starts on first connection in Poland.
- Data can be added later to the same eSIM without a new QR code.
Support is on WhatsApp and email, 7 days a week, if setup goes wrong.
Keeping your home number active
Keep your home SIM in the phone for calls and bank codes, and turn off data roaming on it to avoid roaming charges. If the home line is prepaid, a top-up keeps it alive while you are away.
Options:
- Slashtel sells mobile top-ups to more than 100 countries, delivered in minutes, which keep a prepaid home line active.
- Use the eSIM for data and the home SIM for SMS, so codes still arrive.
- Read how calls, texts and codes work with a data eSIM.
Top-ups are ordered through the top-up page, and there is more on keeping your number active.
First-week catches to avoid
Three things catch newcomers out: an unregistered prepaid SIM is blocked 30 days after purchase, contracts without a PESEL can only be signed in a shop at T-Mobile, and non-EU newcomers have just 4 days to register their address, which is also the easiest way to get a PESEL.
Checklist:
- Register the prepaid card the day you buy it.
- Do not rely on an online contract order without a PESEL.
- Register your address within the deadline for your nationality group.
- Keep the home SIM for codes until the Polish number works everywhere.
- Confirm anything unclear with the operator or the municipal office, as rules and processing times can change.
