I recently set up a GV number and seemingly activated the number for my cell phone, HTC Evo. I can make outgoing calls using the GV# and send/receive texts fine but whenever someone calls the number it gives an 'unable to connect' error and hangs up. Ayone have a solution for this issue?
This is still just my best guess, but I would definitely check to be sure that Google Voice is linked to your cell number and that it is set up to forward your calls. You should see something like this in your settings:
If that's all set up properly then you might want to consider starting a discussion thread over at Google's support forum.
