Mailbox Not Available

[AylenS]

I've been trying to access my mtn voicemail via a landline, using what I thought was the default password. For some reason I'm getting "your mailbox is unavailable at this time". Maybe its blocked after a number of unsuccessful attempts? How do I make it available again?

1. Dial 120 to change your password. If doesn't work -> #2

2. Reset all diverts ##002#
It will also cancel mailbox. Then dial 100, to setup mailbox again.
