You can look up MOBIVOX access numbers for any part of the world under the Access number link in the main menu. For countries where there is more than one "Access Number", there is a drop down pick list of cities.
You can also configure MOBIVOX specific "Access Numbers" in the "Access Numbers" section. When configured, your access numbers are sent to you by email as well as SMS if you have a mobile phone. You can then add these to your mobile address book.
You can also query MOBIVOX by phone for access numbers for a particular country and city. In Voice Command mode say “Access Number” or in dialpad mode press “9”. The selected access numbers are sent via either SMS (if phone is mobile) or email.
