At AT&T, we’re bringing it all together. We’re helping people connect with advanced mobile services, next-generation TV, high-speed Internet services and smart solutions for businesses.
Fast, secure and mobile connectivity – to everything on the Internet, everywhere, at every moment and on every device – is what drives us at AT&T.
Our customers can stay connected from virtually anywhere. It doesn’t matter if they’re driving home from work or headed across the country. Our leading wireless services offer customers the nation's strongest LTE signal* and the nation's most reliable 4G LTE network.** With our recent purchase of two Mexican wireless companies, Iusacell and Nextel Mexico, we’re becoming a leading wireless provider in that country, too.
Customers want video on every screen to enjoy their favorite movies, TV shows, music and sports. We’re setting the standard for delivering video when, where and how customers want it. With our acquisition of DIRECTV, combined with our AT&T U-verse TV service, we’re now the world’s largest pay TV provider. We have nationwide reach in the United States, plus 11 Latin American countries.
