No sound when receiving texts on iPhone

If your iPhone isn't making a sound when you receive text messages, several factors could be at play. First, ensure your device isn't in silent mode or "Do Not Disturb" is active, as these will mute all notifications. Check your text tone settings in Sound & Haptics, and verify that notifications for the Messages app are enabled in Settings > Notifications. Also, ensure your iPhone isn't muted for specific contacts in the Messages app. If the issue persists, try force-restarting your iPhone or resetting all settings.

Turn on your ringer or check if a focus mode is turned on.

That should probably work!
