AT&T is preparing to launch a new text messaging plan while removing two prior options, according to a new report. Citing a leaked image of an internal Best Buy notice, GearLive reports that AT&T is doing away with its prior $5/200 message and $15/1500 message plans, and is launching a new $10 monthly plan that will include 1000 messages, with each additional message costing $0.10. Notably unchanged are the company’s $20 individual unlimited and $30 family unlimited plans. While current customers will be grandfathered in and allowed to keep their current plans, all new customers will have to choose from the new offerings beginning January 23.
