The purpose and role of BIS is defined pretty well here: http://en.wikipedia.org/wiki/BlackBerry#BlackBerry
Do you need more, and how much more?

BIS refer to blackberry internet service ..it is just like an ISP = internet service provider...
Actually, not quite "just like". An ISP provides primary internet connectivity to a computer/network, along with often other services (email, web, and other hostings). Most more recent BBs can, with no BIS-level service and using WiFi only, access the Internet just fine for web browsing and some other services. Further, many can, with just a generic data plan, access the same things via the Carrier Data Network. But, in neither case will any of the BB-proprietary services (e.g., BBM, email, BB Protect, etc.) function at all...all BB proprietary services require subscription to an adequate data plan from the mobile service provider.
There further are many different levels of BIS plans...there are hundreds of carriers in the world, some with dozens of different BB data plans available. Some provide email and social networking only, but no web browsing. Others provide web and internet, but no social networking. And there can be quite a large number of variations given all of the different BB proprietary services. But, in all cases, they are provided by BIS...so BIS itself is the overall umbrella of BB-proprietary services, with the different carrier data plans enabling different mixes of those various available services...it all depends on what the user subscribes to from their mobile service provider.
Hope that helps!
