GV stopped working for my mother on her iPhone a while back. I can't seem to find a fix. It works for incoming calls but she can't make calls out internationally or domestic. Any ideas?
assuming she's paying to make domestic and international calls?
Unless she's calling from a u.s. number to another u.s number?
Make sure that the Google Voice number is attached correctly and it's verified sometimes has to be Reverifeid for it to work and be able to make outgoing calls.
Or try deleting the app and reinstalling it, also in the settings make sure it's set that you allow Google Hangouts to make phone calls.
Good luck.
