Opensignal analyzed 5G users’ experience across three measures: The average speed of the 5G connection when users have an active 5G link, or 5G Download Speed; the time users spend connected to 5G represented by 5G Availability; and the overall speed 5G users experience across different generations of mobile technology, or Download Speed Experience.

Do you want your 5G fast or widely available? Those are the choices most of us have when looking for a 5G connection. The fastest service is millimeter-wave but it has limited range. Low-band connections are easier to find but you may not see much of an increase in speed.

Carriers are building out 5G infrastructure at a steady pace. In November, Verizon added more cities to its 5G Ultra Wideband coverage.  In December, T-Mobile launched a 5G hotspot.

Once you’ve figured out whether or not your neighborhood has 5G connectivity, you’ll need to understand what flavor of 5G you’ve got. Each carrier has its own collection of labels for low-band, midband, and millimeter-wave service.

AT&T and T-Mobile both are using low-band 5G for the foundation of their nationwide networks. Low-band has decent range but isn’t much faster than LTE connections. Sprint went with midband connections to build its first 5G connections, which are now part of T-Mobile. Millimeter-wave has the fastest speeds but the smallest range. CNET describes it as a “souped-up Wi-Fi hotspot.” Verizon’s 5G Ultra Wideband service operates on millimeter-wave frequencies.

OpenSignal’s June 2020 report on the 5G rollout in the US found that Verizon wins the 5G Speed award with 494.7 Mbps real-world average speed. OpenSignal awarded T-Mobile the 5G Availability award because its 5G users spend 22.5% of time connected to 5G. AT&T and Verizon tied on overall download speed of 42.6 Mbps and 41.0 Mbps, respectively. OpenSignal is an independent analyst group that assesses consumer mobile experience. OpenSignal’s December 2020 report examines the 5G experience in 15 leading markets.

Here’s a list of where each major US carrier provides 5G service. This list also includes available 5G phones from each carrier. This information is current as of Jan. 5, 2021. The list will be updated as new cities and counties get 5G service.

AT&T’s 5G coverage

AT&T has a 5G map that you can use to check coverage by ZIP code.

AT&T has the most confusing mix of names for its 5G services:

• 5GE: A combination of 4G LTE technologies, not true 5G 
• 5G: Low- and midband service
• 5G+: Millimeter-wave service

T-Mobile’s 5G service

T-Mobile’s commercial nationwide standalone 5G network covers about 260 million people in 7,500 cities and towns, according to the carrier. Customers in those areas can expect average download speeds 7.5x LTE with an average speed of 300 Mbps with peaks up to 1 Gbps,  according to the company. T-Mobile also has a map to search for 5G connectivity.

SEE: Research: How 5G will transform business (TechRepublic Premium)

T-Mobile is using its entire 600 MHz footprint with this new standalone network. This low-band frequency is not as fast as millimeter-wave frequencies but it does have more range. T-Mobile has built its 5G network with low-band, midband, and millimeter-wave components. The company also is testing 4G Home Internet in select areas; the new T-Mobile’s nationwide 5G Home Internet rollout is still in the works. 

T-Mobile has been expanding its midband 2.5 GHz network and recently announced availability in these cities: 

• Atlanta
• Chicago
• Houston
• Los Angeles
• New York City
• Philadelphia
• Washington D.C.

T-Mobile has been expanding its midband 2.5 GHz network throughout the year. On Sept. 29, 2020, the company announced that customers in 121 new cities have midband 5G service. Those cities include:

Verizon’s 5G coverage 

Verizon’s CEO Hans Vestberg joined Tim Cook at Apple’s Hi Speed event to announce an expansion of the company’s 5G Ultra Wideband services and a new nationwide 5G network. 

Verizon’s new network uses DSS technology and the existing networking infrastructure that the carrier’s LTE traffic runs on currently. This approach makes it easier to expand low-band 5G offerings quickly and without a significant new investment, similar to what AT&T and T-Mobile have done.

Verizon offers its fastest connectivity in 61 cities as of December 2020. The newest cities on the list are in bold:

Albuquerque, NM
Akron, OH
Anaheim, CA
