You asked if someone tried to do it and already got a link where a BBC journalist bought a phone location data two years ago (that is, this being a thing is absolutely not news). Here's an independent russian newspaper estimating how much it'd cost to get all this data on the black market (note that they don't even question if it's possible to do it as everybody knows that it is possible) https://thebell.io/million-za-vseh-skolko-stoilo-rassledovanie-bellingcat-o-navalnom https://thebell.io/million-za-vseh-skolko-stoilo-rassledovan... They list which databases you'd buy it from and for how much. Their total estimate is about a million rubles, ~$13000 -- Here's another large russian newspaper: https://www.kommersant.ru/doc/4616645 https://www.kommersant.ru/doc/4616645 "For Navalny's investigation internet and some cash was enough" - "Experts interviewed by "Kommersant" confirm that flight receipts with passport numbers of passengers, their phone numbers and geo-tagged billing of the latter can be found on the black market at a price of 2-40 thousand rubles per request."
