T-Mobile Poland, part of the Deutsche Telekom group and formerly branded as Era before its rebrand, has built a reputation for consistent performance in cities and along Poland’s main travel corridors, backed by the same international infrastructure standards T-Mobile applies across its European markets.
Quick answer: T-Mobile sells prepaid tourist SIMs at shops throughout Poland, requiring a passport or ID for registration. Pricing sits in the middle of Poland’s four networks, and T-Mobile’s particular strength is consistent city and corridor performance, making it a solid choice for travelers focused on urban and intercity travel.

Comparing T-Mobile to the other networks
