Hi, I have an RC7620. I am trying to get operator name using both AT and QMI commands. I have noticed that for some SIMs, the at+cops? gives out the correct operator name, but libqmi doesn’t. I tried this API, which keeps returning error code ‘5’ (probably QMI\_CORE\_ERROR\_TLV\_NOT\_FOUND), for AT&T SIM, though ‘at+cops?’ gives the correct information. qmi\_message\_nas\_get\_operator\_name\_output\_get\_service\_provider\_name() If anyone has seen this before and has some fix or inputs, kindly share. Regards, Sai. ---
