After introducing the A-List feature nearly two years ago, AT&T has decided to scrap the feature completely for new customers. Existing customers will be allowed to keep their existing A-List feature on their account.
Statement from AT&T:
With automatic addition at no-cost of AT&T’s Mobile to Any Mobile offer for our wireless customers with an unlimited messaging plan, AT&T A-List is being discontinued for new users. Existing A-List users are not affected. We have seen a very enthusiastic response to the value of Mobile to Any Mobile which lets users with an unlimited messaging plan call any mobile number in America, regardless of the wireless provider.
