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.
