T-mobile Polska S.A.

T-MOBILE POLSKA S.A. is a Polish mobile network operator headquartered in Warsaw, and is part of the T-Mobile brand used by Deutsche Telekom’s subsidiaries. Public T-Mobile materials also describe B2B activity that expanded after integrations with GTS Poland (2015) and later with T‑Mobile Polska Business Solutions / former T‑Systems Polska (2017).

In public routing registries the company is associated with AS12912, and third‑party datasets list multiple IPv4/IPv6 prefixes announced under that ASN. PeeringDB contains an entry for AS12912, but detailed exchange presence is not consistently documented across open sources.

User feedback visible on Trustpilot is largely negative, with recurring complaints about customer support and service handling; the overall sentiment skews poor. Independent tech commentary in Poland also points to very low app/service ratings, though opinions vary by channel.
