4G LTE & 5G Coverage In Seattle

The table below shows the proportion of Seattle with coverage from different cellular technologies.
Network4G Coverage5G Coverage
Don't be alarmed by Dish's lack of 4G coverage in Seattle. Dish has a newly-built network that's 5G-only.

US Cellular And Dish Roaming Coverage

US Cellular does not have native coverage in Seattle. However, some US Cellular subscribers may still have coverage in Seattle thanks to roaming agreements.

The 32% figure for Dish may understate what subscribers in Seattle experience after accounting for roaming agreements.

Millimeter Wave 5G

Parts of Seattle have millimeter wave 5G coverage. This novel celluar technology offers extremely fast speeds, but the coverage potential is limited. Millimeter waves aren't well-suited for traveling long distances.

AT&T ?
T-Mobile ?

Millimeter wave coverage in Seattle is likely sparse (mostly limited to dense, outdoor areas like popular parks or sports stadiums).

Seattle Cell Signal Strength

There are 2,782 map hexes within the census-defined boundaries of Seattle. The table below shows the proportion of hexes at various levels of signal strength. Where both 4G and 5G coverage is available, data is drawn from whichever technology offers a stronger signal.


For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.

Due to data-reliability concerns, 446 hexes in Seattle that fall in bodies water, along rivers, or near shorelines are excluded from the table above.

Crowdsourced Coverage Data In Seattle

Coverage Critic has 95,178 crowdsourced data points from 1,466 map hexes within the boundaries of Seattle. Data is available for AT&T, T-Mobile, and Verizon.
