If you haven’t yet done it, set up voicemail on your phone. Do so even if you plan on using another voicemail service, such as Google Voice. That’s because carrier voicemail remains a valid and worthy fallback option when those other services don’t work.
Even if you believe your voicemail to be set up and configured, consider churning through these steps, just to be sure:
Open the Phone app.
Touch the Action Overflow icon and then choose the Settings command.
On some phones you need to touch the Menu icon to access the Settings command.
On the settings screen, choose Call Settings.
On the call settings screen, choose Voicemail or Voicemail Service.
Choose My Carrier, if it isn’t chosen already.
Or, if it’s the only option, you’re set.
When the My Carrier option is chosen, the phone number listed for voicemail is your carrier’s voicemail service. You can confirm that number by choosing the Setup or Voicemail Settings command on the voicemail screen.
If your Android phone features speed dial, long-pressing the 1 key on the dialpad connects you with your carrier’s voicemail service.
Some versions of the Phone app feature a Voicemail icon on the dialpad. Use it to quickly connect to your carrier’s voicemail service.
Your phone may also feature a Voicemail app, which you can use to collect and review your messages.
Complete your voicemail setup by creating a customized greeting. If you don’t, you may not receive voicemail messages, or people may believe that they’ve dialed the wrong number.
Setting Up Google Voice And Voicemail
After getting and enabling your new Google number, you need to set up Google Voice and Google’s voicemail service on your Android device. If you haven’t used Google Voice before, then follow the steps below to set up your new Google Voice account on your Android device.

You should now be taken to the Set up voicemail screen. Tap on Next.
Tap on Configure to set up the voicemail service. You will now receive an Access Request popup. Tap on Allow.
