Pedestrians walk past a Kyivstar mobile carrier service center in downtown Kyiv on June 10, 2020.
Mobile operators — Kyivstar, Vodafone, and lifecell — know everything about Ukrainians: who they are, where they are, what they like and even how they spend their money.
These carriers are the only providers of the mobile internet, 3G and 4G, in Ukraine. And since nearly 70% of Ukrainians use mobile phones to surf the web, operators know a lot about these people, including apps they use, their location and data about their phone calls.
