To access the interface on your phone, you would simply "call" the number #12345* where 12345 is your five digit PIN. So if you made your PIN as 98765, to access the interface, just go to your phone's dialing (or home) screen. Then press the seven keys #98765* and hit SEND. The phone will act like it's making a call but then the interface will appear and the call will hang up. You will then be inside the interface.
