The Security Service of Ukraine (SBU) said it had arrested two locals from the Kyiv region for allegedly supplying Moscow with SIM cards used to help navigate drones during airstrikes. Namely, to the cities of Naberezhnye Chelny and Yelabuga in Tatarstan, where factories producing combat UAVs are located,” it added. An increasing number of downed Russian drones have been found with Ukrainian SIM cards, likely intended to bypass GPS jamming by relying on cellular triangulation for accuracy. However, the use of mesh modems found on newer Russian drones also suggested that they were used to enable direct communication between drones, creating a network that keeps them linked even if one signal is lost. The SBU said the suspects were caught red-handed with smartphones containing evidence of communications with their FSB handlers and EU-based accomplices, along with an unspecified number of SIM cards.
