check whether your mobile phone is AT compatible or not

my mobile phone Siemens serie 35

Do you mean Siemens C35 handset?
It does support AT Commands. you can test it by connecting it to PC's COM port.
Open connection at 9600 8-n-1 and type "AT" and hit enter.
you must get a reply "OK" from phone. test it!
