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:
Cellular Modem
MODEM Status
Model: SIM5360
Network Registration: Searching
Provider:
Signal: -69 dBm
Mode:
State: NetWait
Mux: Status up
PPP: Not running
GPS: Not running
I can't get an ICCID
Cellular modem configuration
SIM ICCID: (power cellular modem on to read) Power mode of cellular is now on
This is the log output

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
