AT&T has announced that starting tomorrow, select customers will get unlimited mobile calling to any mobile number in the U.S., regardless of carrier. According to the announcement, the new feature will be free for any AT&T customer who is on a qualifying Nation or FamilyTalk plan and who is also signed up for an unlimited messaging plan. Existing customers will need to visit a special website—www.att.com/anymobile—tomorrow to activate the feature. Notably, AT&T has yet to specify which Nation and FamilyTalk plans will qualify for the feature; we will update this story as soon as that information is available.
Update: AT&T has posted a brief comment to its Facebook post saying that customers “need to be on a qualifying voice plan, either AT&T Nation 450 & 900 Or AT&T FamilyTalkNation 700 and higher.” [Thanks, Michael S]
Update x2: AT&T has announced further details of the feature. To sign up, eligible customers need to sign in to their online account, remove their existing unlimited messaging plan, and add the new unlimited messaging plan that includes “Mobile to Any Mobile” calling. More information is available from the company’s Frequently Asked Questions page.
