I have an EG25-G Quectel module in my PinePhone and it behaves strange when it just booted.
If the device booted and the suspend cycle is triggered without any phone call or text received, the modem will after resuming because of a phone call send an URC with VOICE <some data>
but also NO CARRIER
.
This behavior doesn’t happen if a call or text was received after booting before going into suspend.
pinephone:/home/dylan# echo 'AT+COPS?' | atinout - /dev/EG25.AT -
+COPS: 0,0,"CARRIER CARRIER",2
OK
pinephone:/home/dylan# echo 'AT+CREG?' | atinout - /dev/EG25.AT -
+CREG: 0,1
OK
pinephone:/home/dylan# echo 'AT+CEREG?' | atinout - /dev/EG25.AT -
+CEREG: 0,4
OK
It seems that the EG25 module is not properly initialized?
I tried already different SIM cards.
