5G issues on my iPhone

Our Apple iPhone 15 Pro phones do not recognize the T-Mobile 5G network. We never had any issues with our iPhone 12's connecting to 5G. These newer Apple phones are challenging me to explore Android phones. I wish Apple would focus more on network capabilities and battery power rather than camera functionalities. We tried different settings, performed a reset, and removed the eSIM and installed a new eSIM. Nothing has improved the signal strength. When I asked Apple if it could be software related, I heard an emphatic no.
