Q：When a mobile phone is used as a Wi-Fi hotspot to share internet access, the mobile data connection drops and the phone becomes unusable when a call is received.
A：1. Normally, mobile phones use the 2G network for voice calls by default, disconnecting other network signals when a call is connected. Therefore, enabling VoLTE on your device allows you to share the network during calls, as VoLTE uses the 4G network signal for voice calls, ensuring the same signal strength for both voice and internet access.
2. The path to enable VoLTE is: Settings - Mobile network - VoLTE. Turn the switch on, and ensure your SIM card also has VoLTE enabled in your carrier's services.
