While the BlackBerry solution is now a household name, what is less well known is that there are two main BlackBerry smartphone mobile connectivity options, and they are quite different. The first is the BlackBerry Internet Service, in which your mobile carrier acts as a liaison between your email and your BlackBerry smartphone.
The BlackBerry Internet Service offering is a standalone service, a BlackBerry Enterprise Server integrates with Microsoft Exchange/Outlook. With a BlackBerry Enterprise Server, the data from these platforms is accessible directly from the BlackBerry smartphone, which enables near real-time mobile access to corporate data.
If you’re using a BlackBerry smartphone solely for personal email, then a BlackBerry Internet Service account may be all you need. But if you’re a business user and are only using BlackBerry Internet Service, you’re leaving lots of important functionality unused.
