The map shows where T-Mobile fiber internet is available and T-Mobile speeds in different areas. When different max speeds are available at different addresses within a hex, color is determined by the fastest speed.
Colored hexagons indicate where T-Mobile services at least one address. Internet service is not necessarily available at every location within a colored hex.
Select a city to show T-Mobile Fiber availability in the surrounding area.
Along with fiber, T-Mobile also offers fixed wireless. See T-Mobile 5G Home Availability. Another map shows the availability of all T-Mobile technologies.
Zoom out to view T-Mobile Fiber availability and speeds at the national level. However, the map works best when zoomed in, exploring T-Mobile Fiber availability in specific regions.
The availability or speed of service at a single address can dictate the color of the hexagon the address falls within. Accordingly, national-scale views with large hexagons will smooth over local variations in internet availability and speeds.
Broadband Map's information on T-Mobile fiber availability relies heavily on the December 2025 data from the FCC's Broadband Data Collection program (published May 2026, with FCC revisions through July 2026).
