Chris, The modem power on/off is not instance. Think of power off like shutdown on a computer (with the shutdown taking a minute or so), and power on like turning on your computer (with the actual boot sequence taking a minute or so). You can see this with ‘cellular status’ and the states ‘powering on’, ‘powering off’, etc. The reason I mention that is that I suspect the reason you don’t see ICCID is the modem is not fully powered on and boot up complete. I suggest you reboot the module. Then watch ‘cellular status’ to see the modem power on. When fully on, check the ICCID and hopefully it will be there. If not, then there is some problem reading the SIM (but then seeing a network registration status would not make sense). As to the registration searching, that is pretty low level and controlled by the modem. It simply can’t find a network to connect to. Are you certain you still have 2G coverage there? https://www.congstar.de/hilfe-service/netzabdeckung/ Regards, Mark.

For the second time within a month I have no GSM connection and I'm not able to reestablish the connection.
The SIM card is "Congstar" Prepaid (with enough money on the card). The Network is 2G and connections are normally without any problems here.
What I can see, is that I have a signal around -70 dBm, but can't get a network registration:

Last time this happened I was able to get the connection back by performing some esotheric button pressing on "Start Modem", "Stop Modem" and "Power cellular Modem on" in the WebUI, but now it does not help.
I compiled the newest version yesterday and I did some reboots of the module and I even pulled the fuse to completely power off my OVMS in the car, but no success.
Is there anything I can do to do some more troubleshooting? Any thoughts on possible causes?
Thanx
Regards
