Polish SIM cards found inside Russian drones in Poland, raising new questions over 2025 incursion

Polish SIM cards were discovered inside some of the Russian drones that breached Polish airspace during a significant incursion in September 2025, as reported by Polish outlet RMF24. The SIM cards, found in recovered Gerbera drones, allow for connections to local cellular networks for various functions. However, it remains unclear what purpose the Polish SIM cards served in these Russian drones, as the investigation has yet to disclose their usage.

The SIM cards were discovered in among the more than 30 Russian Gerbera drones that entered Polish airspace on September 9-10, 2025, during an attack on Ukraine. The incident, which took place overnight, saw the drones enter from the east and crash at 27 locations across Poland, prompting Polish forces to intercept and shoot down multiple drones.

Poland also communicated with NATO throughout the operation, which led to the closure of four airports due to the military activity. The mass incursion marked the first time Polish forces had used weapons against Russian aerial objects entering their airspace since Russia's full-scale invasion of Ukraine. However, after months of investigation, Polish prosecutors were unable to identify the perpetrators and closed the case without classifying the details.

The investigation also found no irregularities in Poland's military response to the drone incursion, as the military acted within their right to use force against hostile objects.
