| Plan | Price | Network | Speed | After daily allowance | IP breakout |
|---|---|---|---|---|---|
| Unlimited · 500 MB/day at full speed · Flexible 1–365 days | US$1.99 | Play / Orange | 5G | 512 Kbps | FR/NL |
| 3.0 GB · 30 days | US$2.99 | Play / Orange | 5G | — | FR/NL |
| 50 GB · 180 days | US$54.99 | Play / Orange | 5G | — | FR/NL |
Hotspot and tethering are allowed on every plan we sell. Plans are data-only unless the plan page states otherwise — only selected plans carry calls or SMS. IP breakout is where your traffic exits the network, which is not always the country you are visiting. Prices and networks are read from the same catalogue that powers our machine-readable pricing file, so this table cannot go stale against checkout.
Why an eSIM beats roaming in Poland
Poland's mobile market is competitive and cheap, led by Play with Orange, Plus, and T-Mobileclose behind. A travel eSIM connects to the strongest local network automatically — the same signal a Polish phone uses — so you skip the airport SIM queue and arrive already online. Because Poland is in the EU, many Europe-wide eSIMs run on the same plan across the continent, handy if your trip pairs Kraków with Prague, Berlin, or Budapest. The US State Department recommends keeping a working phone for travel updates; an eSIM handles that cheaply.
Keep your home SIM in the phone with roaming off and set the Poland eSIM as your data line. Your number still receives calls and two-factor codes, while maps, messaging, and rideshare run on the cheap local plan. For a nearby comparison see the Germany eSIM guide or the broader Europe travel eSIM guide.

FAQ
QWhich carrier is best for an eSIM in Poland?
APlay is Poland's largest mobile network by subscribers, with Orange, Plus, and T-Mobile also offering strong nationwide 4G/5G. A travel eSIM connects to the best available local network automatically, so you get city and intercity coverage without buying a physical SIM at the airport.
QHow much data do I need for a Poland trip?
AFor a week in Poland, 3–5 GB covers maps, messaging, and photos; 10 GB suits heavier use, hotspotting, or a two-week trip. Plans start at a few dollars. Because Poland is in the EU, many regional eSIMs also work across the rest of Europe on the same plan.
QDoes a Poland eSIM work in Kraków, Gdańsk, and on day trips?
AYes. All major Polish carriers cover Warsaw, Kraków, Wrocław, Gdańsk, and popular day trips like Auschwitz-Birkenau (Oświęcim) and the Wieliczka Salt Mine. Coverage is strong along the rail and motorway network between cities.
QeSIM or roaming for Poland in 2026?
AAn eSIM is almost always cheaper than US carrier roaming, which often runs US$10–15 per day. You install the eSIM on Wi-Fi before you fly and arrive with data already working, while keeping your home number for calls and two-factor codes.
Bottom line
For Poland in 2026, buy a Play/Orange-backed eSIM, install on Wi-Fi before you fly, and keep your home SIM in the phone for your number. You land in Warsaw or Kraków already online for maps, trains, and rideshare, and you skip a punishing roaming bill. Compare with the Europe travel eSIM guide if your trip spans several countries.
