Problem with GE863-GPS

Hi everyone.

I’m having a problem with one module that i have (GE863-GPS)

I have a code that configures the module for GPRS.

The line i’m having problems with is the following:

AT#SCFG=1,1,300,90,600,50

everytime i send it then i get ERROR

The exactly same code works fine on another module.

Why is this happening? Please help out.
