By Sinead Carew NEW YORK (Reuters) – ATT Inc plans to give consumers options to save money on mobile data fees as soon as this quarter while offering sponsors a new way to entice consumers to use their services. The company announced details on Monday at ATTs developer conference at the Consumer Electronics Show in Las Vegas. The offering will let sponsors subsidize consumer data fees, which have gradually become more expensive in recent years as phone companies charge for mobile web-surfing based on how much data their customers download. ATT, the No. 2 U.S. mobile operator, compared the offering to 1-800 telephone services where businesses such as florists pay for inbound calls with a view to attracting more consumers.
