setting up google voice with a gears3 and numbersync
i had a hard time setting up my gear s3 watch and my gs7 active and integrating the numbersync feature that allowed me to use the watch for calls.
i would get some calls going to google voice, and some going to att voicmail
here is what appears to be working for me.
set up number sync on your phone and gear s3
now turn off number sync using the s3 watch
set up a google voice account and add both your phone and s3, make sure you verify each device with the 2 digit code reply for each
call and have them turn off any att voicemail services
have att confirm they see the google voice forwarding on each device
now, from the watch turn on numbersync
now if i call my google voice number, or my mobile number and i reject it at the phone , watch or if it times out , google voice will pick up.
you cannot verify or setup google voice on the s3 while numbersync is activated
