Today's cell phone bills can be as long as they are confusing.
But, not reading that fine print could cost you.
Maybe you've heard this, "Ding!" and received a text message, like this and this is a real example "The placement of a donkeys eyes on its head enables it to see all four feet at all times."
Federal regulators say AT&T customers were billed for unsolicited texts, or spam, just like that, to the tune of "hundreds of millions of dollars."
Reporter: "They call this cramming?"
Jessica Rich, FTC: "That means placing charges, cramming charges on bills that you don't know are there."
Now, AT&T will pay 105-million dollars in penalties including 80 million refunded to consumers for the unlawful billing where the fee shows up as an unauthorized $9.99 monthly subscription.
AT&T says it discontinued billing for those type of third-party charges last year. And, the FTC is presently suing T-Mobile for the same thing.
So, here's our experts take-away.
Bob Sullivan, "you might get a spam text message and be inclined to ignore it. That's a big mistake. When you get a spam text you should probably run to your computer and check on your bill."
In addition they say look for vague terms, like usage or service charge. Watch out for $4.99 or $9.99 items, those are the most popular fees third-party companies charge and check your total bill. If it's higher that usual, call your provider and make sure you didn't get crammed.
