BG96 RSSI 99 no network detected

IoT Modules LPWA Module
1

Hello.

I just started with BG96.
I would like to register on the network at first, but when reading RSSI still have 99 and ber=99.

I sent a command: AT+COPS?
Response from BG96: +COPS: 0

as well:
AT+CPIN?
READY

AT+QNWINFO
+QNWINFO: No Service

Why I cant see any network operators?
Maybe I forgot about something? Some initial command?
I will be grateful for your help with starting with this.

Additional info:

In acording with this:

AT+COPS=1,2,“26003”,8
OK

AT+COPS?
+COPS: 1

AT+QNWINFO
+QNWINFO: No Service

AT+CSQ
+CSQ: 99,99

PROBLEM SOLVED.
As author of solution from link above wrote:
"Repeat Manual Operator selection & Signal Quality check until +CSQ is below 30… "
so when you repeat:

+QNWINFO: “CAT-M1”,“26003”,“LTE BAND 20”,6200
OK

AT+CSQ
+CSQ: 19,99

before you reister network ， pls set APN first，with AT+CGDCONT .

for the failure reason , pls check the below AT :

at+cereg?;+cgreg?;+cops?;+qcsq;+qnwinfo

AT+QMBNCFG=“DEACTIVATE”

AT+QMBNCFG=“autosel”,0

reboot module, then try these command again：

AT+CGDCONT?

AT+CGCONTRDP

AT+COPS?

AT+CIMI

AT+QCSQ

AT+QMBNCFG="LIST‘

AT+QCFG=“emmcause”

you can refer to aT command doc as the below
