Poland is one of the cheapest places to buy data anywhere
A verified 50 GB Airalo plan costs $35 — $0.70 a gigabyte. Even the 20 GB works out at $0.90. EU visitors need buy nothing at all.
EU visitors: buy nothing
If your SIM is from an EU or EEA country, Polish data comes out of your normal domestic allowance under roam-like-at-home. There is nothing to buy and nothing to install. Check your provider's fair-use cap if you are staying for months; otherwise close this page and enjoy Kraków.
British, American, Australian and Canadian visitors are the ones who need something. Roaming charges from those markets typically run $5–15 a day, which a $4 eSIM beats before lunch on day one.
Poland is one of the cheapest countries we track
The floor is $0.70 a gigabyte: Airalo's Lekko 50 GB for 30 days at $35, read from Airalo's own checkout on 13 August 2026. Better still, you do not have to buy 50 GB to get a good rate here. The verified 20 GB for 15 days is $18, which is $0.90 a gigabyte. In most countries a rate under a dollar means committing to 50 GB; in Poland it does not.
That matters because Poland is where an earlier version of this page went badly wrong. It read the small plans, decided the market topped out around 20 GB at roughly $1.35 a gigabyte, and never looked at the top of the list. The real rates are half that.
| Plan | Price | Per GB | Status |
|---|---|---|---|
| Airalo Lekko, 50 GB / 30 days | $35 | $0.70 | verified |
| Airalo Lekko, 20 GB / 15 days | $18 | $0.90 | verified |
| Airalo Lekko, 20 GB / 30 days | $19 | $0.95 | verified |
| Nomad, 50 GB / 30 days | $45 | $0.90 | verified |
| Nomad, 20 GB / 30 days | $19 | $0.95 | verified |
| Airalo Lekko, 10 GB / 30 days | $12 | $1.20 | verified |
| Nomad, 10 GB / 30 days | $14 | $1.40 | verified |
| Airalo Lekko, 5 GB / 30 days | $8.50 | $1.70 | verified |
| Saily, 10 GB / 30 days | $12.99 | $1.30 | verified |
| Nomad, 3 GB / 30 days | $9 | $3 | verified |
| Saily, 1 GB / 7 days | $4.49 | $4.49 | verified |
Airalo rows were verified on the provider's site on 13 August 2026 and Nomad's on 17 August 2026. The rest are indicative figures from our dataset rather than live quotes. Lekko is Airalo's product name for its Polish plans, not a network.
The practical reading: the 20 GB at $18 or $19 is the plan for almost any trip. Buying 3 GB or 5 GB to save $10 costs you two to three times the rate and leaves you rationing maps.
Unlimited is poor value here specifically
Airalo's Lekko unlimited is $18.50 for 5 days, $27 for 7 and $69 for 30, all verified. Nomad's verified unlimited undercuts it: $11 for 3 days, $18 for 5, $25 for 7 and $33 for 10. Holafly lists $20.50 for 5 days and $36.50 for 10, verified.
Now the arithmetic that only works in a cheap market: at $0.70 a gigabyte, $27 of metered data is 38 GB, and $69 is 98 GB. You would have to be running a small office off your phone for unlimited to pay in Poland. Buy the 50 GB and forget about it.
Coverage, and the mountains
Polish coverage is strong. LTE reaches 99.85% of the population, the national average speed in our data is 52 Mbps, and 5G is expanding quickly. Orange Polska is the largest operator with the widest 4G coverage including rural areas, T-Mobile has the widest 5G deployment, and Play often tops speed tests in the major cities.
The gaps are all wilderness: the Bieszczady Mountains in the remote south-east, forested parts of the Mazury lake district, remote Beskidy mountain trails and the more isolated Kashubian highlands. If your trip is Warsaw, Kraków, Gdańsk and Wrocław, coverage is not something you need to think about. Emergency calls work on any Polish network without an active plan.
Which network your plan actually uses
Airalo does not publish a host network for Poland — the Lekko name is a product, not a carrier, and an earlier version of this page printed Orange and T-Mobile next to those plans as though it were a fact. It was not.
Nomad and Saily publish no Polish host network either — an earlier version of this page credited both with Orange and T-Mobile, and neither seller states it. Holafly names none either — the Orange, T-Mobile and Play listing this page used to credit to it came from our own data rather than from the seller. Given that all four Polish networks are strong and the gaps are limited to genuine wilderness, this is one of the few countries where not knowing is not a real problem.
Buying locally
There is no dedicated SIM shop at Warsaw Chopin; you buy at Relay convenience stores or newsstands. In town, Orange, Play, T-Mobile and Plus all have stores in the Warsaw and Kraków centres. A passport is required for registration, and an airport tourist data package runs around $8 in our data. Given a verified 20 GB eSIM at $18, the local SIM is only worth the queue if your phone cannot take an eSIM.
Full pricing for every provider is on the Poland hub.
Common questions
Do I need a SIM card for Poland if I am from the EU?
No. EU and EEA SIMs roam in Poland at domestic rates, so your usual allowance covers you. Only long stays need a fair-use check with your provider.
What is the cheapest data plan for Poland?
Airalo's Lekko 50 GB for 30 days at $35 — $0.70 a gigabyte, verified on 13 August 2026. For a shorter trip the verified 20 GB for 15 days at $18 is $0.90 a gigabyte, which is still cheaper than most countries' best plan.
Which Polish network do travel eSIMs use?
Airalo does not disclose one for Poland, and neither do Saily or Nomad. Holafly names none either, and the Orange, T-Mobile and Play answer this page used to give for it came from our own data rather than from the seller. In practice Polish coverage is strong on every operator, with gaps only in the Bieszczady, Beskidy and remote Mazury.
