Did you recently sign up for Google Voice, only to find out that when people call your old cell phone number, AT&T's voicemail system answers the call instead of Google Voice? If so, follow the instructions below to forward your cell calls to Google Voice instead of AT&T voicemail.
In this example, my Google Voice number is (406) 555-1234 and my cell phone number is (404) 333-1234.
Open up the Phone application and enter the following codes, as if you were making a call.
- Forward unanswered calls:
*61*YOURGVNUMBER# and press Call, e.g. on my phone, I entered *61*4065551234# Call.
The phone should display:
Setting Activation Succeeded
Voice Call Forwarding
When Unanswered - Forward calls when busy or when you ignore a call:
*67*YOURGVNUMBER# and press Call, e.g. on my phone, I entered *67*4065551234# Call.
The phone should display:
Setting Activation Succeeded
Voice Call Forwarding
When Busy - Forward calls when phone is off, out of service area, or in airplane mode:
*62*YOURGVNUMBER# and press Call, e.g. on my phone, I entered *62*4065551234# Call.
The phone should display:
Setting Activation Succeeded
Voice Call Forwarding
When Unavailable
