Interesting.
In 2020, 5G speeds in the US did not come anywhere close to the 10 Gbps commonly associated with the latest cellular technology. The data collected from 1 October 2020 to 31 December 2020 by our speed test , which measures the quality of Internet connections on millions of devices yearly, shows that 5G networks in the US did not deliver the super cellular connections that we were promised.
I have a 5G phone, the Samsung Galaxy S-20. However frankly I do not see much difference in performance. Most of the time I am using Wi-Fi.
