AT&T has filed a formal complaint with the National Advertising Division (NAD), a branch of the Better Business Bureau dedicated to assisting the advertising industry in self-regulation. AT&T accused Comcast of making unsubstantiated claims in its wireless telephone service advertisements. The NAD agreed with AT&T and requested that Comcast modify three of its claims about Xfinity Mobile service. To begin, the NAD requested that Comcast modify its claim that its Xfinity Mobile service is the “fastest mobile service,” as well as disclose that its “fastest mobile service” is based on combined WiFi and cellular speeds and that the claim is true only within its WiFi footprint or when connected to WiFi. Second, the NAD requested that Comcast withdraw its Xfinity Mobile “most reliable,” “highest ranked,” and “best network” claims. Thirdly, the NAD asked Comcast to clearly and conspicuously disclose that an Xfinity Internet subscription is required for Xfinity’s mobile service.
