How can I access my voicemail from another device?

Call your number from any other device. The moment you hear the voicemail message, press the asterisk. Next, you enter your phone number followed by your voicemail PIN, and you have access to your own voicemail.

Your voicemail has to be active and you have to know your PIN code. Otherwise, this won't work! Haven't done so yet? Set up your voicemail first.
