Yes...but there are a 5 percent that tries DOWNLOADING the interwebs on their phones. This 5% is putting big pressure on the BIS service and degrading the service for everyone. What you guys must remember is that even though you might not be connected to the same towers as these erm...naughty boys/gals....your data goes via the same pipe to the BIS server. So, even though they are not congesting your tower...when your data reaches this pipe it hits a bottleneck and this is where the problem comes in.
This whole excercise is to get those people to stop and for everone to use the service what it was intended. Unlimited BROWSING....NOT DOWNLOADING. Also, Jannie mentioned that this 100mb limit is not set in stone. Should they feel it to be called for...then the limit can be reassessed.
