I’m developing my dissertation with a BG95-M3 modem. I’m trying to perform network registration but did not succeed because the SIM gets errors “(U)SIM failure” and “(U)SIM not inserted”. Then I noticed that the USIM slot was just powered ON for a few seconds when the modem is turning ON, then just goes to 0v. I believe the schematic is fine (image attached). I use just 6 pins and the (U)SIM Card Detection is disabled. So, there is some command to turn on the USIM slot, to start receiving power?
