Polish prepaid SIMs can offer substantial data for a modest initial payment, especially if you want a local number. Orange has a clearly priced English-language starter, while T-Mobile's introductory offer has a lower initial outlay; Roafly suits visitors who want to arrange their data before departure.
Poland SIM Card Prices at a Glance
These options serve different needs. The comparison separates an inclusive starter purchase, a starter plus mandatory top-up, and a package whose physical SIM cost still needs a store quote.
| Option | Data and validity | Initial payment | Main distinction |
|---|---|---|---|
| Orange English-language starter | 75 GB / 30 days | 30 PLN total | Domestic calls, SMS and MMS included |
| T-Mobile GO! M introductory offer | 30 GB base / 30 days, plus promotional bonuses | 15 PLN: 5 PLN starter + 10 PLN top-up | First package fee waived; activation required |
| Play XXL 5G with unlimited-data promotion | Unlimited domestic data while qualifying paid cycles remain active | 50 PLN package fee; confirm physical SIM total separately | Suits heavy use; package conditions apply |
| Roafly | 10 GB or 20 GB / 30 days | $10 or $18 respectively | Data; Play and Orange networks; no Polish number |

Your first decision is whether you need a Polish phone number. If maps, messaging and bookings cover your needs, you can arrange a Poland eSIM before departure on a compatible, unlocked phone.

Which Polish Prepaid SIM Should You Choose?
Orange: a straightforward 75 GB starter
Orange's English-language starter is useful when you want clearly identified purchase with a substantial allowance. Ask specifically for the 75 GB English-language starter, because other Orange packs have different bonuses and activation conditions.
The English starter terms explain the payment:
-
30 PLN buys the starter.
-
15 PLN from that amount pays for the first 30-day package.
-
15 PLN remains in the main account.
-
The included service renews at 45 PLN if the renewal conditions are met.
That remaining balance is useful credit, but the purchase still costs 30 PLN. Comparing the deducted package fee would understate what you pay at the counter.
Activation of this promotion can take up to 24 hours after registration, and the starter is available while stocks last. Keep that timing in mind if you need data immediately after buying it.
T-Mobile: low initial cost with an activation step
T-Mobile's GO! M introductory offer has a low initial outlay, provided you complete its activation steps.
The practical sequence is:
-
Buy the 5 PLN starter and register it.
-
Activate the SIM, then top up by at least 10 PLN within the required 30-day window.
-
Activate GO! M in the app, by sending AKTM to 8066, or with *600*1*3#.
-
Wait for confirmation before relying on the bundle.
The package includes unlimited domestic calls, SMS and MMS, plus a-time 200 GB activation bonus lasting 30 days. It subsequently renews at 35 PLN every 30 days.
The separate 50 GB headline includes a bonus for topping up by 35 PLN. That bonus does not apply to the minimum top-up.
Play: worth considering for heavy data use
Play's XXL 5G package is worth examining for heavy data use. Its unlimited-data promotion requires Play na Kartę 3.0 and an active qualifying package.
The initial promotional period lasts 186 days, followed by six 600 GB bundles. Qualifying package renewals are required to continue benefiting.
Before buying:
-
Get the physical SIM and first package quoted together.
-
Have the assistant identify the tariff and activate the relevant promotion.
-
Distinguish the current package period from the longer promotional period.
Play's offer averages 25 PLN per month across two months: 50 PLN for the first, zero for the second. Someone visiting for month pays the first charge; the average understates that immediate expense.
Where to Buy and Register Your SIM
Start with an operator shop if you need assistance
Visit an official Orange, T-Mobile or Play shop if you want help with passport registration and package activation. Ask staff to handle both during your visit, allowing for any separate package activation window.
Other buying channels include:
-
Newsstands and convenience stores: useful for purchasing a starter, with registration available at participating outlets.
-
Supermarkets and petrol stations: established buying or top-up channels, depending on the operator.
-
Online ordering: convenient when the delivery and identity-verification process fits your documents and arrival plans.
Buying the plastic card and registering its number are separate steps. Before paying at a retailer, ask whether that outlet can register your passport and help activate the intended package.
Airport shopping needs the same checks. We would not build an arrival plan around an unconfirmed counter, exact starter stock or assumed price. If you need a working connection before leaving the terminal, arranging your data before the flight removes that dependency.
Bring your passport and register the number in your own name
Polish prepaid numbers require registration. Foreign visitors can use their passport through the supported in-person process; obtaining a Polish PESEL number is not a universal prerequisite.
Bring your passport, the starter and its SIM details. T-Mobile's registration requirements explicitly distinguish the passport route for foreign visitors from other forms of identity verification.
At the shop:
-
Ask for prepaid service, commonly called na kartę.
-
Present your identity document and have the number registered in your name.
-
Agree on the total payment and the exact package.
-
Complete the required top-up and activation.
-
Turn off Wi-Fi and test mobile data activation is confirmed.
Keep the SIM carrier with its PUK code. Your phone also needs to be unlocked and have a physical SIM slot if you are buying a plastic SIM.
Online registration has narrower document rules
The availability of registration does not establish that every foreign passport will be accepted. Bank-based verification can depend on a supported Polish bank account.
T-Mobile's video-verification instructions currently identify Polish identity cards and Ukrainian passports as supported documents. Visitors carrying other passports should use its in-person registration route rather than assume the process will work for them.
You can also top up through physical retail channels. Play supports vouchers and terminal top-ups, so managing a prepaid balance need not depend on opening a Polish bank account.
Bonuses, Renewals and EU Roaming
Read annual data totals as a schedule
Polish offers frequently advertise thousands of gigabytes spread across a year. Those totals often combine a starting bonus with later allocations that require package renewals.
Orange's 9,900 GB promotion, for example, distributes data across 12 periods. It is a different offer from the English-language starter compared above. The useful number for your holiday is the allowance available during your stay, with its own expiry and activation conditions.
Marketing-consent bonuses are another separate component. Decide whether you want to give those permissions; avoid treating an optional bonus as part of the unconditional base allowance.
Separate package renewal from automatic top-ups
Prepaid packages can renew from the money already on the phone account. Automatic top-ups or card-funded subscriptions add a separate payment arrangement.
If you want a single visit's worth of service, ask how to disable package renewal and leave automatic top-ups off unless you deliberately want them. This keeps a short trip from turning into an payment setup.
Domestic data and EU roaming are different allowances
Large Polish data allowances should not be treated as equivalent allowances for travel elsewhere in Europe. The roaming limit belongs to the exact package and may differ from the domestic bonus.
Before crossing the border, establish:
-
Which destinations the package covers.
-
The data allowance available there.
-
Whether your introductory or discounted cycle has different terms.
-
What happens after that allowance runs out.
Calls from Poland to an overseas number are also a different service from using your Polish SIM while roaming abroad. Domestic unlimited calls alone should not be your basis for making international calls.
Local SIM or Roafly eSIM?
Local prepaid makes sense when you want a Polish number, included domestic calls or a large data allowance. It also works with an unlocked phone that has a physical SIM slot but lacks eSIM support.
Roafly is useful when your priority is arranging internet access before travelling. Its Poland plans are data, list Play and Orange, require no identity verification, support top-ups and allow hotspot use across the purchased allowance. Match the choice to your trip:
-
Local calls and substantial data: consider Orange's English starter or a qualifying local prepaid bundle.
-
Low introductory outlay: examine T-Mobile's offer and complete its activation steps.
-
Data arranged before arrival: use Roafly on an unlocked, eSIM-compatible device.
You can install Roafly before departure and keep your primary SIM available on a compatible dual-SIM phone. Set the travel eSIM as your mobile-data line and manage your home line's roaming settings separately.
If you want a broader provider comparison, our guide to the best eSIM options for Poland covers that separate decision.
Frequently Asked Questions
Can I buy an eSIM from a Polish mobile operator?
Yes. Orange and Play offer prepaid eSIM routes, and T-Mobile supports eSIM options and SIM-to-eSIM replacement. Identity verification still applies, so check that the purchase or registration route accepts your documents before paying.
Can I keep using WhatsApp with my existing number?
Yes. You can keep WhatsApp registered to your existing number while using another SIM or eSIM for internet access. Changing the mobile-data line does not require changing your WhatsApp number.
Poland's local prepaid offers can be good value when their setup and renewal conditions fit your stay. Compare the money you must pay today, then choose the allowance, phone-number features and registration route that you will actually use.
