General Motors and AT&T will bring 5G cellular connectivity to millions of GM vehicles coming off the assembly line over the next decade in the U.S.

GM and AT&T are working together to set the benchmark for automotive connectivity with a fifth generation cellular network architecture to meet the needs of an all-electric and autonomous future.

  • Faster navigation, mapping and voice services


5G connectivity will first be available in select model year 2024 vehicles.


Additionally, through GM's fifth generation network, current 4G LTE-equipped model year 2019 and newer vehicles will experience faster connectivity speeds and many of the same performance benefits of future 5G-equipped vehicles. Current Chevrolet, Buick, GMC and Cadillac owners in the U.S. with 4G LTE-capable model year 2019 and newer vehicles will easily migrate to the new network infrastructure once available. 

This rollout is part of GM and AT&T's broad strategy to launch the world's largest fleet of 5G-enabled vehicles and the culmination of a two-year collaboration, including test-driving connected vehicles in GM's 5G proving grounds in Milford, MI.


AT&T has the nation's most reliable 5G network, covering more than 250 million people across the country. From 2016 to 2020, AT&T invested more than $110 billion in its wireless and wireline networks, including capital investments and acquisitions of wireless spectrum and operations.
