Blocking your phone number for outgoing calls
When you place a call from your VisorPhone, the Phone application reveals
your phone number to the person you’re calling. If your service provider
supports caller ID blocking, you can prevent revealing your phone number
to people you call.
Note: Because caller ID blocking information is stored by the network,
it’s a good idea to check the current network settings both before
and after you change the Block outgoing caller ID option.
1. Press the Phone button on your VisorPhone.
2. Tap the Menu icon .
3. Under Options, tap Call Preferences.
4. Enable the Block outgoing caller ID option.
5. Tap OK.
