quick choice  

You have the option of setting up call back on your voice mail. This means that the Voice Mail service calls you immediately after saving a message. After entering your security code, you can access your voice mail and check your message. Just as the Voice Mail service can call you on your mobile phone, it can also call you at another (alternate) phone number.

If the Voice Mail service does not succeed in reaching you, it will try again after 10 minutes, then after 30, 30, 60, 120, and finally 240 minutes.

Even if you have call back activated, the Voice Mail service tries to notify you by a text message. From the Main Menu you can utilise quick choice for:

delivering messages to your mobile phone
delivering messages to your alternate number
entering the alternate tel. number
deactivating delivery of messages
