Earlier this week, Verizon announced it is bringing back unlimited data plans
after years of selling capped data packages. Now, ATT will be doing the same
. ATT will let any current or potential customer buy an unlimited data plan
. Until now, only DirecTV customers were able to purchase unlimited data from the carrier. PhoneDog reports: ATT says that starting tomorrow, February 17, its Unlimited Plan will be available to all customers. The plan will include unlimited data, talk, and text, and customers with the plan will also be able to travel to Canada or Mexico and use their plan just as they would at home, with zero roaming charges. ATT's Unlimited Plan also includes Stream Saver, which will optimize video streams to 480p. However, Stream Saver can be disabled if you'd like. One feature that's missing from ATT's Unlimited Plan is mobile hotspot usage, which is notable because the unlimited plans from the other three major U.S. carriers do include some mobile hotspot. Finally, it's worth noting that after 22GB of usage, ATT Unlimited Plan customers may have their speeds slowed during times of network congestion. This policy is also in place at the other three major U.S. carriers, with Verizon's threshold being 22GB, Sprint's 23GB, and T-Mobile's 26GB. A single line on the ATT Unlimited Plan will cost $100 per month. Each additional line will cost $40, but ATT will offer the fourth line free, making the cost for a family of four $180 per month.
