Good to know: Your voicemail PIN is like a password. Just as a password is needed to receive email, your PIN must be entered each time you get your voicemail messages. Voicemail comes with a default PIN, the last 6-digits of your account number. We suggest you change your default PIN even if you're not using voicemail.
You can't use *86 to call on another phone - it will connect to the voicemail of the calling phone. From another phone, you need to dial your own number.
