Best eSIM for Poland: Real Prices Compared for Kraków, Warsaw and Beyond

Kraków's old town, Warsaw's mix of glass towers and rebuilt history, and the Baltic coast up around Gdańsk make Poland one of the more varied city-hopping trips in Central Europe — and since most visitors move between two or three cities rather than staying put, a data plan that covers the whole country matters more here than on a single-city break. I checked live pricing across the 121 providers we track for Poland, refreshed daily, so here's what the actual pricing looks like today.

Quick-answer picks

• Cheapest way to get connected: Yesim's 500MB / 1-day plan at $0.50 — a light entry point for confirming your setup before a longer trip.
• Best value for a week between Kraków and Warsaw: Yatelo's 1GB / 7-day plan at $1.41 — one of the cheapest weekly rates we track anywhere in Europe.
• Best for a longer stay or a full month: Yatelo's 3GB / 30-day plan at $2.55.
• Best raw price per GB: Yatelo's 20GB / 30-day plan at $7.29 — normally the strongest deal if you need real data volume.
• Best unlimited option: eSIMCard's 5-day Unlimited plan at $5.83, or AirSims' 30-day Unlimited at $18.15 for a longer stay.

Provider-by-provider breakdown

Yesim has the lowest headline price in our Poland catalog across 36 real plans — 500MB/1 day at $0.50 is a genuinely useful minimal option, and they currently run a real discount code too:

co:sim (84 plans, from $0.99 for a genuine Unlimited day pass) has the largest single lineup of any provider we track for Poland — useful if your trip length doesn't line up neatly with anyone else's standard tiers.

Yatelo is a standout value pick across the board — cheapest at the weekly length (1GB/7 days, $1.41), a strong pick for a full month (3GB/30 days, $2.55), and a strong price-per-GB in the whole catalog (20GB/30 days at $7.29). If you're not sure how long your trip is or how much data you'll actually use, Yatelo is a sensible default to check first.

eSIMCard (23 plans, from $1.39 for 1GB/3 days) is normally the cheapest genuinely unlimited option here at $5.83 for 5 days — a strong pick if you're bouncing between Kraków, Warsaw, and the coast and want to stop thinking about a data cap. They currently run a real discount code too:

eSIMCard -10% ESIMKART

AirSims takes over as one of the best unlimited options once you're looking at a full month, at $18.15 for 30 days — a meaningfully better rate than paying eSIMCard's short-stay price repeatedly across a longer trip. They also have a discount code active:

AirSims -10% ESIMKART10

SimOptions (27 plans, from currently unavailable for 1GB/1 day) and Ubigi (58 plans, from $2.00 for 0.5GB/2 days) both sit in the middle of the comparison — reasonable fallback options if a specific tier shape suits your trip better than the leaders above. Real discount code active for Ubigi:

Why prices vary this much

A cheap day-pass and a full month of unlimited both show up under "Poland eSIM," but they're built for different travelers. The cheapest tiers here (Yesim, co:sim, SimOptions) are mostly light-use day-passes — fine for messaging and maps, thin for a full day of active navigation between cities. Yatelo's real strength is pricing efficiently across the entire range rather than winning on just one tier, which is why it keeps coming out strong whether you're comparing a week or a month. eSIMCard and AirSims, by contrast, are optimized specifically for unlimited buyers who'd rather not think about a cap while moving between multiple Polish cities on one trip.

If you're not sure how much data a multi-city Poland trip actually needs, our data usage guide is worth a look before defaulting to unlimited — most travelers use less than they expect, even when city-hopping.

Which plan fits your trip

• A few days in one city: Yesim's 500MB/1-day plan or Yatelo's 1GB/7-day plan, depending on how many days you're actually there.
• A week covering Kraków and Warsaw: Yatelo's 1GB/7-day plan at $1.41 is a strong standard pick.
• A longer trip or a full month exploring the country, including the Baltic coast: Yatelo's 3GB/30-day plan at $2.55, or the 20GB variant at $7.29 if you want real headroom for photo and video uploads.
• Heavy data use across a multi-city trip — video calls home, constant navigation, streaming: eSIMCard's unlimited day-rate options for a short stretch, or AirSims' 30-day unlimited at $18.15 for the full trip.

A few practical notes

Poland is an EU member and part of Schengen, though these plans are priced specifically for Poland rather than bundled into a wider EU roaming rate — every price above reflects real, current Poland-specific pricing. Coverage is strong across the major cities and most of the country; more rural stretches, especially in the east, can occasionally be weaker, the same limitation a local Polish SIM would face.

Install your eSIM before you fly — every provider above activates only once you're in Poland and connect to a local network, so there's no benefit to setting it up early. If you're new to eSIMs entirely, our beginner's guide to how eSIMs work covers installation and activation from the very start.

If your trip continues into neighboring countries — Czechia, Slovakia, or a wider Central European route — check each destination's own pricing separately before assuming one plan carries over; our multi-country trip planner can show you real plans that genuinely cover your whole route if one exists.

Poland's rail network makes city-to-city travel genuinely easy, and coverage stays solid along the main train corridors linking Kraków, Warsaw, Wrocław, and Gdańsk — worth knowing if you're planning a whistle-stop tour rather than settling into one base for the whole trip.
