T-Mobile Retaliates Against AT&T's Negative Ad Campaign With New Anti-AT&T Ads
AT&T's ads, which were posted in The New York Times, The Wall Street Journal, and USA Today, criticized T-Mobile for dropped calls and slow download speeds.
T-Mobile's retaliatory ads question why AT&T attempted to buy the carrier if T-Mobile's network is so unsatisfactory.
The war between AT&T and T-Mobile began in January, when T-Mobile CEO John Legere called the AT&T network "crap," though the relationship between the two carriers soured after AT&T failed to purchase T-Mobile following objections from the Federal Communications Commission and the Department of Justice.
T-Mobile is currently in the process of restructuring, with a plan to eliminate device subsidies and initiate lower monthly plan costs. The company plans to offer Apple products at some point in 2013.
According to Tmonews, the ads are proof prints that have been sent to T-Mobile for final approval, which means they could hit newspapers at any time.
