hide your phone number for outgoing call

Sometimes we need to make a call that the person we call no need to know our number.

here are how to do it on your treo650 gsm.
  • press the green phone button
  • press menu button, the button on the right, over the red phone button
    • select Option / Call Preferences ..
    • or press menu button, then press A on keypad.
    • then give checkmark on Block outgoing caller ID
then when you dial a number, the person who receive your call should only see : private number or somenthing like that on their display.

note: this feature is sometimes optional, you might need to subscribe to your network provider for this.
