AT&T is hitting back aggressively at its competition with discounts, offers and now a new slogan.

AT&T, the nation's second largest wireless carrier, is targeting its competitors in an aggressive manner. New discounts, attractive offers for T-Mobile customers and now a new slogan, are ample examples of  AT&T's fight to achieve supremacy in the increasingly contentious battle among wireless carriers in the U.S. AT&T announced its latest marketing slogan, "Bigger than T-Mobile, faster than Verizon Wireless and more reliable than everybody," at CES 2014, Monday.

AT&T faces tough competition from Verizon and T-Mobile both.  Verizon leads the U.S. wireless carrier charts with maximum user-base and T-Mobile's new "Uncarrier" strategy has attracted a large chunk of users. The new slogan has no mention of the third largest U.S. carrier, Sprint.

In an interview with FierceWireless at the International Consumer Electronics Show 2014 on Monday, AT&T's Mobility CMO David Christopher addressed the new marketing strategy as an aggressive move to keep at par with the highly competitive carrier race.

"We are just letting people know what a great experience we offer," Christopher told FierceWireless. "We want to focus on what we bring to the market and tout our capabilities. We will never go away from that."

The past year, T-Mobile and CEO John Legere  have been targeting AT&T. AT&T started off the New Year by offering T-Mobile customers a chance to switch carriers and get up to $450 credit. The latest slogan not only continues the war with T-Mobile, but also targets Verizon, which has not been involved in the feud so far.

T-Mobile is refusing to respond for the moment and is concentrating on unfolding details of the long-rumored "Uncarrier 4.0" this Wednesday.
