T-Mobile dropping 'largest 4G network' ad was proper, report says

The National Advertising Division said T-Mobile took necessary action last month when it dropped an ad campaign claiming it was “America’s largest 4G network.” The mobile carrier ended its ad campaign in July after using it for a year and a half after the National Advertising Division began looking into it. The group describes itself as an "investigative unit of the advertising industry’s system of self-regulation." At one point, T-Mobile did have the largest 4G network in the U.S., but the group determined T-Mobile could no longer make that claim.
