Report "I need a phone code for my siemens A65 so I can change one of the security functions. At present I can only phone a number if it is in my phonebook otherwise it tells me call barred. I have tried phoning the siemens number in the instruction book but it is no longer available.BenQ siemens cannot help and nor can Siemens who do not deal in mobile phones any longer. Virgin my service provider also cannot help. Can you?"
