Two of world’s biggest mobile companies are fighting over an ad: T-Mobile says it offers “America’s best network”; AT&T CEO replies, ‘You are lying, as always’

AT&T is escalating its decades-long feud with T-Mobile, launching a pointed advertising campaign this week to debunk rival claims and assert dominance over America’s wireless landscape. The campaign, featuring actor Luke Wilson, directly counters T-Mobile’s marketing assertions about network superiority. AT&T Chief Operating Officer Jeff McElfresh told Yahoo Finance that T-Mobile’s ads mislead consumers into believing it operates the nation’s biggest and best network. “When we see claims coming directly from a competitor like T-Mobile with advertising that says they’ve got more towers, leading people to believe they may have the absolute largest and best network, the opposite couldn’t be truer,” McElfresh said. “In fact, T-Mobile’s got the smallest network – over 300,000 square miles smaller than that of AT&T. We own and operate the largest and most reliable wireless network.”
