Things most newcomers don’t know

Registration is mandatory even for prepaid.

Poland requires all SIMs to be tied to an identified person. Buying an unregistered SIM isn't an option, and one bought without proper registration simply stops working.

EU roaming means no urgency on arrival.

Coming from another EU country, your existing SIM works at domestic rates. You can take your time choosing rather than paying airport prices.

Polish mobile is genuinely cheap.

Data allowances that would be premium tier in Western Europe are standard here at a fraction of the price. It's one of the clearest cost-of-living wins in the city.

Common mistakes to avoid

  • Expecting to buy an anonymous prepaid SIM.
  • Paying airport prices when EU roaming already covers you.
  • Signing a 24-month contract before you have PESEL and a bank account.
