The moment that AT&T subscribers have been waiting for since 2010 has finally arrived… but it comes with some strings attached. AT&T on Monday announced that it will be bringing back unlimited data plans for new and existing subscribers, although you’ll need to also sign up for one of AT&T’s pay TV packages to take advantage of them.

Essentially, AT&T is bringing back unlimited wireless data as a carrot to lure in customers to subscribe to DirecTV or AT&T U-Verse. The unlimited plan also includes unlimited talk and text and costs $100 a month for the first phone added, with additional phones costing $40 each. If you have three phones on the plan, adding a fourth phone costs you nothing.

Of course, like with most carrier plans, this plan raises questions about just what a carrier means when it says you have “unlimited” data. AT&T will throttle your speeds during hours of network congestion if you’ve exceeded 22GB per month, so heavy users shouldn’t expect to have 4G connectivity at all times.

Even so, this is better than getting hit with overage fees, so that’s progress. This deal sounds particularly good for people who are already DirecTV or U-Verse subscribers who don’t want to have to worry about paying extra each month for using too much data.
