Hi,
I activated SIM as per the steps mentioned in wedsite and SIM is activated. Then I tried ‘register operator’ Arduino code for Sara R410m NBIoT module. After I run the code I receive 2 operators are available
1.Vadafone.de
2. telekom.de
Then when we select any one operator (I tried both operator separately).
I get following response
“Error connecting to operator. Reset and try again, or try another network.”
Following is the log file . Any help is appreciated
