If you want to use your phone as a hotspot for your PC and do not have access to Wi-Fi, you can tether your phone to your PC via USB to share your mobile data connection. To do this, you need to make sure your phone's hotspot feature is turned on, and then connect your phone to your PC using a USB cable. Once connected, go to your phone's settings and find the tethering or hotspot option. Select the USB tethering option, and your PC should automatically detect and connect to your phone's internet connection. You can then use your phone's mobile network to browse the internet on your PC. Note that mobile data charges may apply, depending on your phone plan.
