I have QUECTEL EC20F
Revision: EC20CEFAGR06A10M4G
When I try AT+CPIN? i get +CME ERROR 10 (Sim is not inserted)
I have inserted the sim and it’s working on a phone.
I have tried AT+CFUN=1 to enable the SIM card but it didn’t work.
Any suggestions regarding this.
I am using an embedded linux Nvidia jetpack 4.3
Also can you share how to get logs from the module in linux.
Hi dear,
please try AT+CFUN=1,1, if you are sure about your PCB design
good luck 
Some components were missing from the board will check the code after that. Thanks.
