A. Check your phone settings to ensure that you are using the correct network mode (e.g., LTE, 5G). Sometimes, switching between modes can improve call quality. You can do this in your phone's settings under 'Network & Internet' or 'Mobile Networks.'

B. If disconnections persist, try resetting your network settings. This can often resolve connectivity issues. Go to your phone's settings, find 'Reset options,' and select 'Reset network settings.' Note that this will erase saved Wi-Fi networks and Bluetooth connections.
