Ah, the humble phone message. Thanks to texting, voice mail is becoming less common. But until it disappears altogether, it’s to your advantage to know how to leave clear messages. In fact, a phone message is sort of like a thank you note: You can earn big respect by leaving a good one… and lose points if your message is annoying or rude.
It's important to mention your follow-up plans in your sales voicemails. Sometimes just the knowledge that you'll call again is enough to entice a prospect to respond. Let them know that if you don't hear back from them, you'll follow up in a few days or next week.

If your voicemail has been set up and you are unable to change your greeting through the 'Voicemail' tab, dial *86 then choose option 4 to change. From a Home screen, tap the Phone app . If an app isn't available on your Home screen, swipe left to access the App Library. Tap Voicemail then tap Greeting (upper-left).
3. To permanently delete the message, click on the trashcan icon, either found below the voicemail details or at the top right-hand corner.
