I had previously been on 2500 incoming text messages per month (and that 2500 number was extremely difficult to find on Rogers' site) and starting getting in the vicinity of 3000 incoming messages per month due to services such as Twitter and Facebook. My bill tripled for a couple months.

Also, the first month I had a data plan, I burned through eight MBs on a two MB plan. Instant $80 in data alone.

And those examples are miniscule compared to others' bills.
