I also noticed that after this problem, at+cpin returns "ERROR", like there was no SIM card (electrostatic problem, ESD ?). I need to remove and replace SIM card before restarting...
Within this period they are working just fine, but after that I found them in power off mode (status LED stops blinking),
like when they are turned OFF with on/off button.
If the modules are again turned on via on/off button, they continue to work without any problems,
but after 3-4 days they again shuts down themselfs ...
