A 4G mobile signal was launched Oct. 2 between Muzeum and IP Pavlova on the Metro C line. By the end of October, it will cover all the way to Roztyly, and the entire metro system should be covered by 2022. This is the first part of the underground track in which passengers can both make calls and surf the internet. The move comes just days before the Oct. 5–6 municipal elections and is part of a wave of projects either being started or announced.
