Attaching PSB and GPS screenshots, as we need to monitor them regularly. At 6:18 to 6:40, we started getting four rings from the PS Booster. The 1st ring had a fairly low intensity, and the operators later dropped it. These times were confirmed exactly with communication with PS operators. again. ====================================================
