Are you using a prepaid phone by any chance?

No, it is not a pre-paid phone. I called in to the support center and they entered the correct settings into the system.

I am having the same issue.  Was this ever resolved?  It seems like a lot of sites claim to have solved this issue (using Google Voicemail instead of AT&T voicemail), but none of them work?  Can anyone help?

I have spoke to multiple AT&T representatives and none of them can.

I'm also experiencing some issues, except that GV has worked flawlessly for me for over a year. Suddenly, yesterday, my call started going to my AT&T voice mail. I've had the techs reset my basic voice mail and removed AT&T visual voice mail (which is a common problem based on what I've read online), but still no luck. I get the below error messages when trying to set GV:

"Couldn't retrieve and save current forwarding number settings. Switch to the new provider anyway?"

Touching yes results in "Couldn't change the forwarding number. Contact your carrier if this problem persists."

I've also attempted to do it manually by doing *004*google voice number# and get MMI code errors. Additional research online has indicated that my conditional call forwarding needs to be reset by AT&T, but it took three calls to technicians to get somebody who would actually do that, not lecture me on how Google Voice is not supported by AT&T and how I'd be better off with AT&T  visual voice mail. Sorry, I need GV to work as I use my Google Voice number in addition to my regular phone number.

this worked for me on 1/24/2013 on my Lumia 920 windows phone 8

When I do the ##02# on HTC One X+ i get the following error message:

"Connection problem or invalid MMI code"

Feb 18, 2013- You have to get to the right dept in AT&T. The AT&T visual v/m is tied to your data plan and in my case they had to actually change the plan to a plan without visual v/m. Only then did my Google voice work completely right. GV was working some of the time, but only now does it work correctly. Had to do this for both of our phones (Moto Atrix, but it is an AT&T issue). Good Luck, AT&T will try to tell you it's a Google issue, just keep telling them the above.

AT&T stopped my call forwarding when I switched phones from the Samsung Rugby to the HTC One (M7). I tried all of the different tricks here to no avail.

However,

I DID find in the SETTINGS-->CALL an option called "Call Forwarding" in which I put my google voice number and it worked. 

I know this is an old thread, but wanted to pass on how this was set-up for my Wireless Home Phone, as I have not seen a conplete description of this anywhere.  

I had recently ported my Vonage number to the WHP...but was not satisfied with the basic vmail functionality.

To set Google Voice as the vmail service for the Wireless Home Phone, I had to simply do the following:

Note: This assumes that you only plan to use the Google Voice number for voicemail...

1. Create a Google Voice Account if you do not already have one.
2. From the WHP, dial **004*1xxxxxxxxxxx# (where the "x" represents the 10-digit US phone #)...you should get a confirmation tone.
3. On Google Voice, in the "Settings>Calls", enable "Do Not Disturb" and uncheck the "Ends in" box.  This will assure the call goes directly to Vmail after ringing on the WHP for the set amount.  Otherwise it rings on WHP, then on Google Voice before going to vmail.
4. Set-up your GV Voicemail options & messages as desired.

Note: I have seen in other posts that were missing a second "*" before the "004".  Exampl:e for number (212) 555-2145...the proper syntax is **004*12125552145  

I realize another way to do this would have been to port my old vonage # to Google Voice directly then just ring the WHP from Google Voice, but my preferred home # had just been ported to AT&T, so did not want to have to deal with chaanging the AT&T WHP number and simultaneously porting the home # to GV.

Y not you directly read on google about it

Is there a way when calling my ATT number to have my original VM play and when someone calls Google Voice number the Google VM plays?
