AT&T says data usage is increasing 40 percent every year. Users are using their smartphones and tablets to stream music and movies more and more.
That costs the company, and AT&T says it has to pass some of those costs along.
So beginning Jan. 22, new AT&T customers will pay $20 for a 300-megabye monthly data plan. Current customers pay $15 for a 200 MB plan. A 3 gigabyte data plan will cost $30 and a 5 gig plan will cost $50 monthly. Current customers pay $25 for 2 gigs and $45 for four.
The pricing only affects new customers, AT&T said.
