The Mi 13's WiFi and hotspot functions can be turned on at the same time. When you use the hotspot feature of the Mi 13, it shares the phone's network signal with other devices, while your phone can still use the WiFi network to surf the Internet. This means that you can share your network with other devices while still keeping your phone connected. Enabling WiFi and hotspot functions at the same time can provide you with a more convenient and efficient network experience.
