4. InstaVoice. InstaVoice does have a visual voicemail transcription, but with a twist. It seeks to provide a simple platform for handling an infinite number of voice messages from any phone number you want.
If you like to keep things simple, opt for a basic greeting. Most voicemail options allow you to record just your name, which lets callers know they’ve reached the right person.

By following this walkthrough, you’ll have your voicemail set up in no time. All you’ll need is your iPhone and a few spare minutes. Begin by tapping the Phone icon that is located on the home screen. Next, you’re going to touch the Voicemail tab that is located at the bottom right of your iPhone screen.
If you’ve already created a custom voicemail on your iPhone, you can tap Play to see how your voicemail sounds. If you’re interested in creating a new message, tap the Custom button. From here, you can start recording your message by tapping Record and tapping Stop whenever you’re finished. Once you’re finished recording, tap on Play to make sure the message comes across as you’d like and hit Save (in the upper right) to save it as your voicemail.
