Thank you for explaining the issue you are facing with calls on your device. From your description, calls work normally when Wi-Fi is enabled, but when you are not connected to Wi-Fi, incoming or outgoing calls sometimes do not work even after resetting network settings.
This behavior is usually related to mobile network coverage, VoLTE/VoWiFi configuration, or carrier-side settings rather than a device hardware fault. When Wi-Fi calling is active, calls are routed through the internet, which is why they work more reliably. When switching to mobile network only, call stability depends on signal strength, network registration, and carrier support in your area.

We recommend checking that VoLTE is enabled, ensuring your SIM card is properly provisioned by your mobile network provider, and confirming that your device software is fully up to date. If the issue continues, your network provider may need to refresh the line or check coverage settings from their side.
