Some aspects of 5G do improve normal cell bandwidth which for internet, basically improves reception. Other aspects of 5G really only make a difference when you are right nearby an antenna, like walking down a city street. The problem is that 5G isn't rolled out everywhere and your phone might try to connect to a 5G antenna when a 4G antenna is much closer and would provide a more robust connection. I rarely see more than 3/5 bars when on 5G but can get much better reception wherever when only using 4G. Only exception was a recent road trip on I-95, there was near constant full 5G coverage.
