I set this as per Verizon. When a call comes in it prompts me to call 901. But when I go to the keyboard and dile 901 it tells me that the call cannot be completed at this time. What did I do wrong?
The password is required but you should be able to embed it in the dial string from the Settings menu on your dial screen. That way you can just hit Voicemail and it will dial, wait however long you define, enter the password, all automagically.
The quality of the message is equally dependent on your location and signal quality as well as the callers phone environment.
I switched to Google Voice for VM service, and have never looked back...
I'll do my best.
I believe the order I did it was:
1) Download Google Voice app
2) Go through set up on there - eventually it should tell you that on Verizon you are unable to set this up directly from your phone
3) Log into your Google account at voice.google.com
4) Click the settings menu
5) Go to the Voicemail tab
6) It should be pretty easy from here - set it up so that Google Voice calls your phone to record your greeting and make it the voicemail provider for your phone
7) Go to the app settings and check the "Voicemail display" box - which will let this act almost exactly like the iPhone visual voicemail - access to your voicemail via your recent calls list (also possible from the Google Voice app)
