About AT&T

AT&T Mobility, operating in the United States of America (part of the broader North America & Caribbean region), is one of the nation's largest mobile network operators. Identified globally by its Mobile Country Code (MCC) of 312 and Mobile Network Code (MNC) of 90, AT&T provides a wide range of wireless services including voice, data, and messaging. With a sprawling network infrastructure, AT&T covers vast swathes of the US, competing directly with other major carriers such as Verizon and T-Mobile for subscribers and market share. Historically, AT&T's evolution involved pivotal acquisitions and technological advancements, solidifying its position in the mobile landscape. From its early days as Cingular Wireless (a joint venture between SBC Communications and BellSouth), to its current branding as AT&T Mobility after AT&T's acquisition of BellSouth, the company has consistently invested in network upgrades, including deployments of 4G LTE and later, 5G technologies. AT&T’s commitment to innovation is visible through their continual pursuit of improved coverage, faster data speeds, and exploring emerging technologies within the telecommunications sector, often pushing the boundaries to enhance user experience.
