@xykon said in Modem's radio showphy, all zeros, is bad?: print(lte.send_at_cmd('AT+CFUN?')) the print(lte.send_at_cmd('AT+CFUN?')) reported 4 before the attach and 1 after lte.iccid() reports: 8944501810180163302" i noticed a funny double-quote at the end but it did that before the modem firmware update and worked fine
