Staying connected in Poland.

Poland has some of the cheapest mobile data in Europe on a network that is genuinely good, and because it is in the EU that data follows you across the union. If Poland is your first stop of several, this page is worth reading before you buy anything.

The short answer

Coverage is excellent across the cities, the countryside and the rail network, so there is nothing to plan around. The interesting part is price. A local prepaid starter from Play, Plus, Orange or T-Mobile Polska costs under 10 dollars for tens of gigabytes, needs your passport because Poland has required prepaid registration since 2016, and because Poland is in the EU that allowance travels with you across the union under Roam Like At Home. Your US carrier charges about 10 to 12 dollars a day (AT&T and Verizon day passes), though AT&T caps its Day Pass at 10 daily fees per line per bill period, about 120 dollars, and covers the rest of that bill period on land, so the daily arithmetic stops past day 10, and T-Mobile's mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps. A Nomad eSIM is a few dollars per gigabyte and is simpler, with nothing to buy on arrival. On price, for a trip of a week or more, the Polish SIM is hard to beat. Never roam pay-per-use, at about 2 dollars a megabyte.

The cheapest data in Europe, and it crosses borders

Polish prepaid is aggressively cheap. A Play or Plus starter with a data bundle runs under 10 dollars for tens of gigabytes over a month, sold in phone shops, Zabka convenience stores and at the airports, with your passport for registration. The networks are good: Play and Orange both have strong nationwide reach and 5G in the cities.

The part that makes this genuinely competitive rather than merely cheap is Roam Like At Home. Poland is in the EU, so a Polish prepaid allowance works in Germany, Czechia, Italy, Spain and the rest of the union at no surcharge, subject to a fair-use policy aimed at permanent roaming rather than a three-week trip. If Warsaw or Krakow is your first stop on a multi-country European trip, one Polish SIM can cover the whole thing for less than a travel eSIM would cost for one leg. It does not cover the UK or Switzerland, which are both outside the zone.

What the eSIM is actually buying you here

We earn a commission on eSIMs and none on a Play starter, so it is worth being plain: in Poland the eSIM is not the cheap option, it is the frictionless one. A Nomad eSIM is a few dollars per gigabyte, activates before you fly and works from landing, with no shop, no queue, no registration form and no need to work out which bundle code to text.

For a long weekend in Krakow that convenience is worth more than the few dollars it costs. For two weeks moving across central Europe, the Polish SIM wins clearly and it is not close. Both are far cheaper than roaming, so the worst outcome here is only mildly wrong.

Coverage, and nothing much else

This section is short because Poland does not give us much to warn about. Coverage is strong in Warsaw, Krakow, Gdansk and Wroclaw, across the countryside, on the trains and in the Tatra foothills, with 5G widespread in the cities. High in the Tatras and deep in the Bialowieza forest you can lose it, which is a hiking note rather than a trip-planning one.

On the alternatives: AT&T and Verizon day passes are about 10 to 12 dollars a day and AT&T caps its Day Pass at 10 daily fees per line per bill period, about 120 dollars, and covers the rest of that bill period on land, so the daily arithmetic stops past day 10, and T-Mobile's current tiers include roughly 5GB on Experience More, Magenta MAX and Go5G Plus, 15GB on Experience Beyond and Go5G Next and 30GB on Better Value. Do not roam with no plan, since pay-per-use is about 2 dollars a megabyte. This guide is written for US travelers departing the US.

Common questions

Quick answers.

Is a Polish SIM card cheaper than an eSIM?

Yes, clearly, for any stay of about a week or more. A Play or Plus starter is under 10 dollars for tens of gigabytes, where a travel eSIM costs a few dollars per gigabyte. The eSIM buys you no shop visit and no registration form, which is worth something on a long weekend and not much on a longer trip.

Does a Polish SIM work in other EU countries?

Yes. Poland is in the EU, so a Polish prepaid allowance works across the union under Roam Like At Home at no surcharge, subject to a fair-use policy aimed at permanent roaming rather than a normal trip. It does not cover the UK or Switzerland, both of which sit outside the zone.

Do I need a passport to buy a SIM card in Poland?

Yes. Poland has required prepaid SIM registration since 2016, so bring your passport to the shop. It is a counter formality rather than a wait, and the SIM works immediately.

How much does it cost to use my US phone in Poland?

About 10 to 12 dollars a day on an AT&T or Verizon day pass, so roughly 70 to 84 dollars a week. AT&T caps its Day Pass at 10 daily fees per line per bill period, so about 120 dollars covers the rest of that bill period on land, while Verizon's TravelPass has no equivalent cap and keeps billing daily. T-Mobile is worth checking first, since its mid and upper tiers include 5GB to 30GB of high-speed data abroad before slowing to 256kbps.

Our own readChecked Aug 2026. The load-bearing point is the one that costs us a commission: Polish prepaid is cheap enough, and EU roaming broad enough, that one starter bought in Krakow can cover a multi-country European trip for less than an eSIM would cost for a single leg. The fair-use policy attached to EU roaming is aimed at people permanently roaming on a foreign SIM rather than a traveler on a three-week trip, so it is mentioned rather than dwelt on. Polish prepaid bundle sizes move with promotions, so the under-10-dollars figure is the current shape of the market.
