Poland's mobile network is served by four main operators: Orange Poland, T-Mobile Poland, Play, and Plus. 4G LTE coverage is comprehensive across Warsaw, Krakow, Gdansk, Wroclaw, and all major cities, with strong connectivity along motorway corridors and intercity rail routes. The Tatra Mountains have coverage in Zakopane and main valley areas, with signal weakening on higher trails and ridgelines above the treeline. The Mazury Lake District has reliable coverage in main resort towns. Białowieża Forest, the Bieszczady Mountains, and some eastern border areas near Ukraine and Belarus may have weaker signal in remote forest and rural zones. MobiSIM connects through supported Polish networks to deliver reliable data across the country's main cities and tourist routes.
