[LTE] AT+CNUM command causing registration failure on LTE devices #1627
AT+CNUM command is used in the registration process just to log the phone number of the inserted SIM. It has been observed that some SIMs in LTE devices have invalid characters in the phone number string that causes this command to error.
This prevents the registration process from completing and the device will blink green continuously.
Remove the AT+CNUM command.
Steps to Test
Test on a unit that was previously causing this error. It should now connect without a problem.
