If you like VVM you will need to make a change...
Probably there is a VVM App from AT&T you could uninstall.
Then on a PC browser sign up for
YouMail. On your phone get the
ISeeVM App. Between the two they will get you all configured. It is the best VVM system I've ever used and I am way happy with it. I just moved off T-Mo to ST and the switch to YouMail was pretty easy and well worth it. It is very feature rich, including greeting my callers by name if they appear in my contacts and giving me readable transcripts inside the App.
