ELS81-US AT+COPS "Unknown operator" | Telit Cinterion IoT Developer Community

Hi there,
On our ELS81-US evaluation board with a Telus SIM card installed, we see the following:
at+cops?
+COPS: 0,0,"TELUS",7
OK
This result indicates "Unknown operator" on the <opStatus> parameter. Is this a problem? How do we correct it?
AT+CREG? indicates that we are registered to the network. See below:
at+creg?
+CREG: 0,1
OK
I assume it should say "Operator available" or "Current operator (registered)".
Thank you,
Cody
Hello,
According to documentation there is the following response to 'AT+COPS?':
+COPS:<mode>[, <format>[, <opName>][, <AcT>]]
OK
ERROR
So your response means automatic mode, long alphanumeric format of <opName>, 'TELUS' operator and E-UTRAN RAT. Ant it's absolutely correct.
<opStatus> is part of the reply for 'AT+COPS=?' command which scans and returns all the available networks.
As for CREG reply it is also correct but please also note that for LTE there is AT+CEREG command.
Best regards,
Bartłomiej
