The map shows where 4 SIWI offers fiber internet service. When different max speeds are available at different addresses within a hex, color is determined by the fastest speed.
Colored hexagons indicate where 4 SIWI services at least one address. Internet service is not necessarily available at every location within a colored hex.
Along with fiber, 4 SIWI also offers fixed wireless. See 4 SIWI Fixed Wireless Availability.
Broadband Map's information on 4 SIWI fiber availability relies heavily on the May 2026 release from the FCC's Broadband Data Collection program (representing ISPs' availability as of December 2025).
