How do I activate BlackBerry internet service?

The BlackBerry internet service (BIS) is complimentary with the activation of a BlackBerry tariff plan and provides you as an individual with the ability to have your personal Internet or work (POP3) email forwarded automatically to your BlackBerry smartphone from multiple email accounts provided by multiple internet service providers' (ISP).

BlackBerry BIS can provide automatic wireless synchronisation of read, deleted and sent items from your BlackBerry device to your supported ISP email account.

If you have multiple email accounts you can choose from multiple "sent from" addresses when sending an email, which allows the receiver to easily identify incoming email.
