AT&T sells mobile phone plans and home internet to households and businesses across the US, and runs a wireless business in Mexico. Its business rests on two networks: a nationwide 5G wireless network and a fiber internet network that is replacing its old copper phone lines. Companies and government agencies also buy private networks, security and connectivity services from its business unit. Most revenue comes from monthly service plans plus device installment payments, and the company pushes customers to combine phone and home internet. AT&T Inc. began in 1983 as Southwestern Bell, took the AT&T name after buying its former parent in 2005, and is based in Dallas, Texas.
