# SIM800 doesn't give GSM location

I have problem to get exact GSM location using SIM800L. I have followed instructions in the manual. But my module just gived me latitude = 0 and longitude = 0. This is what I do with my serial terminal.

AT+CGATT=1

OK
AT+SAPBR=3,1,"CONTYPE","GPRS"

OK
AT+SAPBR=3,1,"APN","RCMNET"

OK
AT+SAPBR=1,1

OK
AT+SAPBR=2,1

+SAPBR: 1,1,"10.230.128.34"

OK
AT+CIPGSMLOC=1,1

+CIPGSMLOC: 0,0.000000,0.000000,2020/02/06,03:45:03

OK


I have used another way to solve this problem. This is my another step to get GSM location.

AT+CLBSCFG=0,1

+CLBSCFG: 0,1,""

OK
AT+CLBSCFG=0,2

+CLBSCFG: 0,2,0

OK
AT+CLBS=1,1

+CLBS: 2

OK


With "AT+CLBS=1,1", I still cannot access my SIM800 to get GSM location. This command always give me time out command without any solution.

Why is this happening? How can I solve this problem?

• Are you sure that your network supports it?
