If you're an AT&T customer and you've ever read your wireless service bill in detail, you may have noticed something called an "Administrative Fee" featured as one of the line items. Up until early this year, that "fee" was typically assessed at $0.76 per postpaid line - not nothing, but over the course of two years of service, it ends up being a little over $18.

AT&T has now very slyly almost tripled the cost in the last six months. Most recently, subscribers getting their statements for June are finding an Admistrative Fee charge of $1.99 per line every month. That brings the two-year cost of this "administrative fee" to almost $50 for each line on your account.
