Start by reaching out to your carrier to see if this is an issue on their end.
If not, reset your network settings in Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This will reset any cellular settings and data on your iPhone, but note it will also remove Wi-Fi/Bluetooth connections.
If that doesn't work, it is likely a hardware issue with the cellular module and should be taken a look at the Apple Store.
