AT&T (T) recently took out a full-page ad in several large newspapers in the U.S. blasting T-Mobile’s network. The company claimed that the carrier’s network has “2x more dropped calls, 2x more failed calls, 50% slower download speeds.” According to TmoNews, T-Mobile will respond to AT&T with its own ads in the next few days. One of the ads references the failed merger between the two companies, noting that “if AT&T thought our network wasn’t great, why did they try to buy it?” The second ad mocks the carrier, claiming T-Mobile is keeping AT&T up at night, and the last advertisement asks readers if they can “see the beads of sweat” in the AT&T ad. T-Mobile’s aggressive response to AT&T comes shortly before the company is rumored to unveil its new “uncarrier” strategy that looks to shake up the mobile industry by eliminating two-year contracts.
