Here are some other ways.

1. They could email you. 2. They could send you a SMS. 3. They could let you view your bandwidth usage by logging into their site. 4. They could provide an application (desktop or mobile) to keep track of your bandwidth and alert you at certain points.

My provider (T-Mobile in the UK, using a mobile 3g dongle) send me an SMS, and the connection software has lots of graphs and numbers.

They still send interstitial content warning me that I've exceeded my fair-use limit. It's a bit annoying because I very carefully checked what the limits were before I signed up.

What's worse is that they use weird, broken, IP addresses and horrible proxies for image mangling.

I use T-Mobile as my mobile carrier and as far as I know they do numbers 2, 3, and 4 that you listed here. I know this because I have received an SMS when I neared my 2GB of unlimited 4G data transfer. I also have logged into their site and used the app on my phone (HTC One S) to monitor my data usage. The phone app even tells you how much data was used by each app and when. It is fantastic. Could that be so hard for Comcast?

My ISP gives emails at 50%, 80% and of course 100%. They also do options 3 and 4 (no idea about 2) but the emails are so very easy, and knowing you've hit 50% gives you time to mitigate before you get capped.
