Currently, I am using Quectel BG-95 Module and Vodafone SIM for network. I have checked that cellular module is getting power or not. It’s getting and LED is blinking which indicates that Power(Vdd_Supply) is coming.
Also, Checked SIM_VCC & SIM_DET, Nano_SIM_CLk.
All are working fine.
Then I have checked SIM serial number able to get but still facing issue of Network registration is failed.
See results of AT+Commands as below :
