I am testing my device (HL7800) and it seems to not be able to find any network.
at+cops? +COPS: 0
What does this response mean?
all other configuration is correct and tested with other devices successfully but with different sim cards.
For example I am getting this response on a different sim card: +COPS: 0,0,“1nce.net”,9
(this device is in a different country also)
