If you use a 5g mobile phone to make a call, there is no big difference in the experience with your 4g use. It should be said that the voice fluency of the call under 5g signal should be better and the signal is stronger, but for some people, the voice call experience is not strong, and the difference may be more obvious from the network speed. Because the speed of the 5g network is much faster than that of the 4G signal network
5g mobile phone terminals can use 5g signals to make calls, and can also fall back to 4g network calls, while 4g mobile phones can only use 2g or 4g calls.
