Frontier is mostly a DSL internet provider that began as the Citizens Utilities telephone company in the 1930s. Frontier acquired Verizon’s landline assets in 2009, including DSL lines and some FiOS fiber. Since then, Frontier has slowly expanded both networks through acquisitions, but DSL is currently Frontier’s primary business, serving over eleven million locations across 25 states.5 Frontier’s fiber is still extremely limited. The company announced five million fiber connections to homes and businesses as it conveniently launched its Fiber 5 Gig plan on February 29, 2023.1 Frontier expects to reach 10 million fiber connections during its Wave 2 expansion—some of which will be upgrades from current DSL lines—by 2025.2
