Most households here report a wired plan: 85% of households in ZCTA 85140 list a cable, fiber optic or DSL subscription, a higher share than Arizona's.

Should the FCC National Broadband Map show something for your lot that a provider contradicts, open that location on the map and submit an availability challenge. When you are ready to weigh the listed companies, compare internet providers, and San Tan Valley internet providers is the city hub.
Start with the builder or the previous owner, and ask what was run through the walls and where each run ends. Then ask the provider whether a technician must visit before service starts.
Ask each company whether that line belongs to it and whether a new order at your address could use it. Ask CenturyLink which connection type it would provide there.
Call the company, give the address exactly as it appears on your property records, and ask whether the home can be found by its lot details. Note who you spoke with and the date.
