Placing calls with Google Voice
Placing calls with Google Voice is almost the same as placing calls via your mobile
carrier, depending on whether you have a Google number and how you have
configured Google Voice on the phone.
1 Call a contact just as you would without Google Voice.
2 If you’ve configured Google Voice to ask whether you want to use it each time you
place a call, touch
Call with Google Voice in the dialog.
If you’ve configured Google Voice to use it for all calls, this dialog doesn’t appear.
Google Voice displays a message, reminding you that you are placing the call via
Google Voice.
If the call is a toll call, Google Voice plays a message with the per-minute charge
and the number of minutes at this rate you have remaining in your Google Voice
account.
Continue with the call as you would without Google Voice, as described in “Placing
and receiving calls” on page 77.
