I have a EC200UEUAA 4G Module on a evaluation board (Evaluation Board EC200X V1.3).
I configured the main UART port output port of URC.
When I power on the module, I get
+CPIN: NOT READY
When I enter AT+CPIN? As an AT command,
AT+CPIN? +CME ERROR: 10 (SIM not inserted).
I’m sure that sim card is not broken and the module and sim card was working properly before.
This situation began to happen right after I started to activate the PDP context.
Thanks for your help.
