Hello,

This seems to be an issue with the SIM card.. Could you verify the SIM card using the following commands after programming Serial LTE Modem sample and the latest MFW:

AT+CFUN=4
AT+CFUN?
AT%XSYSTEMMODE=1,1,0,0
AT+CEREG=5
AT%CESQ=1
AT+CFUN=1
AT+CEREG?

AT#XPING="www.google.com",45,5000,5,1000
 

If you are able to ping google, but the connection to nRF Cloud still have issues, please do share the log and the modem trace..

Best Regards,

Swathy
