AT&T announces unlimited data plan for all customers

AT&T on Thursday announced the return of its unlimited data plan that will launch Feb. 17.

Now, all four major US carriers offer an unlimited data plan, as customers demand more data for streaming video.

The plan will be available to all consumer and business postpaid AT&T wireless customers. AT&T Unlimited Plan will include unlimited talk, text, and data on four lines for $180.

AT&T said after 22GB of data usage, it may slow speeds during periods of network congestion, which is becoming pretty standard with these type of plans.

AT&T is hitting back at the unlimited data plans announced by Verizon, Sprint, and T-Mobile earlier this week. ZDNet compared each of these unlimited plans and found them comparable.

Previous unlimited plans from AT&T required customers to be DirecTV subscribers.

AT&T’s pricing of $180 is after a $40 credit for the fourth smartphone line, which will start after two billing periods. Prior, customers will pay $220 per month for the unlimited plan.
