Think of it as a toll-free 800 number for streaming audio and video.
The telecom giant's so-called Sponsored Data program is intended to make wireless users less squeamish about accessing data-heavy services that can quickly chew up their minutes under many plans.
Here's the thing: If other wireless providers follow suit — and they probably will — it will give an advantage to big content companies that can subsidize people's listening and viewing. Smaller companies and start-ups would be hard-pressed to compete.
What's more, this doesn't really address the biggest problem. Everyone's Internet access charges for wireless and fixed lines are soaring even though only a handful of streaming video services account for the lion's share of usage.
Netflix is responsible for almost a third of North American cable and phone-line Internet traffic from 9 p.m. to 12 a.m., according to network management firm Sandvine. Add YouTube into the mix, and the two services make up just over half of prime-time Net traffic.
When it comes to wireless, YouTube is the big dog, accounting for 27% of data streaming.
Netflix represented just 4% of wireless streaming in the first half of last year, Sandvine said. But that's double the company's total in the same period a year earlier, indicating rapid growth among users of mobile devices.
Tom Wheeler, chairman of the Federal Communications Commission, said Wednesday that the agency would watch closely to see how AT&T's program plays out.
"Be sure," he said, "that if it interferes with the operation of the Internet, that if it develops into an anti-competitive practice, that if it does have some kind of preferential treatment given somewhere, then that is cause for us to intervene."
The last thing authorities want is for network providers to pick winners and losers among content providers.
AT&T clearly sees that there are big bucks to be made in wireless data streaming. In the third quarter last year, the company said, data revenue hit $5.5 billion, up nearly 18% from the same three months a year earlier. Almost 1 million wireless subscribers were added in the quarter.
"The future for us … is about building a video delivery capability," AT&T Chief Executive Randall Stephenson said at a recent investor conference. "And that's where the capital is going to be going over the next three years."
What he means is the company will be building out its wireless network, and subscribers' monthly fees will largely foot the bill.
Yet why should everyone be saddled with the same financial burden when the wireless airwaves are dominated by users of just a few services?
If you mostly send text messages rather than watch episodes of Netflix's "House of Cards," why should you be equally responsible for your service provider's need for additional capacity?
Digital rights advocates make a big deal of what's known as net neutrality, the idea that all content should be considered equal in the eyes of network providers. That is, a Netflix or Google shouldn't be able to pay more to network operators like AT&T for their content to receive special treatment.
I get it. It's better if online services compete on a level playing field.
AT&T says its Sponsored Data won't be any faster than other content and thus won't violate federal net neutrality rules. Verizon, for its part, is suing to overturn those rules and expects a verdict in coming weeks.
In any case, it seems pretty clear that streaming video places the greatest strain on telecom networks.
The average broadband Internet customer pays about $41 a month for service, according to the WhiteFence Index of utility charges. If you're a Netflix subscriber or a heavy YouTube user, that may seem like a pretty good deal.
If you're not into streaming video, you're still helping pay for your Internet service provider's network costs so that others can watch all those data-dripping movies and TV shows.
AT&T's Sponsored Data program addresses this unfairness in a limited way by shifting some wireless costs to the content provider. Ralph de la Vega, head of AT&T Mobility, called this "a win-win for customers and businesses."
"Customers just look for the Sponsored Data icon and they know the data related to that particular application or video is provided as a part of their monthly service," he said.
The upshot, however, is that more people will download rivers of data onto wireless devices. This will require more network capacity, which may not be covered by whatever fees content providers pay into the Sponsored Data program.
Net neutrality notwithstanding, the reason that coach seats on airlines cost a lot less than first class is because you get far less service and comfort. People who aren't using their computers or mobile devices as home theaters shouldn't be paying the same prices for Net access as people who are.
"While Sponsored Data will be pitched as a way to save customers money, it's really just double charging," said Matt Wood, policy director of the advocacy group Free Press. "The customer is still paying for the connection and won't get a refund just because Facebook or YouTube or ESPN are also paying for some data usage now."
Think of it like this: Toll-free 800 numbers — an AT&T invention — originated in the 1960s. Since then, your land-line phone bill has only gone up.
Toll-free wireless streaming might seem like a money-saver, but it's unlikely your monthly bill will go down.
What's needed is a system that requires people who drink deepest from the Internet, either by fixed line or wireless device, to pay more to slake their digital thirst.
Or everyone else should pay less.
