AT&T’s 5G Coverage

Last updated: July 2020

AT&T is deploying two different types of 5G:

  • Millimeter wave 5G: This 5G service is extremely fast, but very bad for covering large areas. Millimeter wave 5G is almost only used in dense, urban areas and does not penetrate buildings well. AT&T has branded its millimeter wave service as 5G+.
  • Low-band 5G: This makes up the bulk of AT&T’s 5G coverage. It’s decent for speeds, but not nearly as fast as millimeter wave 5G.

By my counting, AT&T has started offering millimeter wave 5G in parts of at least 35 cities. In July 2020, AT&T suggested its low-band 5G covered over 200 million people.1 I expect AT&T’s 5G coverage will expand substantially over the next year.

Coverage maps

State-specific 5G coverage maps are available on AT&T’s website. At this time, I have not found any AT&T maps that specifically show AT&T’s millimeter wave coverage.

AT&T’s 5G bands

AT&T uses at least three different bands for 5G coverage.

  • n5 (850MHz)
  • n260 (39GHz)
  • n261 (28GHz)

AT&T’s 5G-compatible phones

As of June 2020, AT&T offers five 5G-capable phones.
