I have the $23 4G 6GB plan.
Having a 4G plan does not prevent you from accessing the 5G network. Most phones will automatically select the strongest signal. So sometimes, my phone will show that it is on 5G, even though I only pay for 4G. My phone will access the 5G network, but the speed will be throttled to less than 100mbps. As long as it works, you can just leave it alone.
Some people with 5G phones with 5G plans will complain that they only get a 4G/ LTE signal. That is probably because their location is too far from the tower for them to pick up the 5G so it defaults to the longer range 4G/LTE.
In certain circumstances, there is an advantage to switch your preferred network settings from 5G to 4G/LTE. 5G maybe faster than 4G, but its range is much less. If your phone is at a certain distance from the tower where 5G starts to cut out, your phone will switch back and forth between 5G and 4G as it searches for the strongest signal. In that situation, you may experience temporary drops in signal during the switching. In those situations, customer agents have advised me to just switch the preferred Network setting to 4G/LTE only so that your phone locks on to the more stable signal with the longer range. This advice is the same even if you have a 5G phone and a 5G plan.
