Visual Voicemail is a special type of answer machine service on iPhone that lists your messages. You can activate Visual Voicemail by text once you’ve activated voicemail.
- Switching on Visual Voicemail: text «VVM ON» to 935.
- Switching off Visual Voicemail: text «VVM OFF» to 935.
You’ll get a text straight away to confirm Visual Voicemail has been activated (or deactivated).
