Geting Location name using SL8090 AT Command

I read the post
https://forum.sierrawireless.com/t/finding-lat-long-without-gps/4517/9

Tried with following AT commands.
AT+CNMI=2,0,2,0,0
AT+CMGF=1
AT+CSCB=1
AT+CSCB=0

On giving AT+CBM? command, ERROR is coming.

Can someone help me? how can i get location name?
