Thanks，I have check the AT commands ，they are correct . but after the commands AT+COPS=3,0;+COPS?;+COPS=3,1;+COPS?;+COPS=3,2;+COPS? the output are： +COPS: 0,0,"FFFFFFFFFFFFFFFF",2 +COPS: 0,1,"FFFFFFFFFFFFFFFF",2 +COPS: 0,2,"46001",2 obviously，the "FFFFFFFFFFFFFFFF"s are incorrect . I have try the AT command through serial port in my host ,it is the same as above. but if I use "at+cops=?",it will response the correct output.
