I am working with the module Q24
And came across a problem.
My problem is that the module can not identify network
And AT + WSHS call returns a value of 1
What do I need to get The Sim Holder is open
Did you check the +WIND indications.Check the WIND indication once,to check if SIM is getting registered or not,SIM rack is closed or open(for more details about WIND indications refer to AT command guide).
Also check with AT+CSQ command ,the signal strength and AT+CREG command,if SIM is getting registered.
