Fixed wireless internet — including 5G home internet services — is available from AT&T Internet and T-Mobile, reaching 50% of addresses (well above the national fixed wireless average of 32%).

Satellite internet (Starlink, HughesNet, Viasat) reaches addresses that wired broadband can't.

Some providers continue offering voluntary low-income discounts.
