Enable USB Tethering auf Realme
USB tethering shares the mobile data connection of your Realme phone with a connected PC or laptop through the USB cable. Compared to Bluetooth tethering, it uses less battery, because the transfer runs over the wired connection instead of a wireless radio link.
The feature only stays active while the USB cable is plugged in and the connected device is recognized. If the laptop shows no internet access despite an active data connection on the phone, USB tethering is usually still switched off in the system settings, or the cable connection was interrupted briefly.
Turn on USB tethering
Open Tap on Settings ➔ Tap on Connection & sharing ➔ Enable or disable USB tethering on your Realme phone. Connect the phone to your PC or laptop with a USB data cable first, otherwise the option stays greyed out.
Once enabled, the connected computer picks up the phones mobile data as its network connection. Turn the toggle off again once you are done, since an active USB tethering connection keeps mobile data running in the background.
If the toggle will not switch on, check whether the USB cable is a data cable and not a charging-only cable, and confirm mobile data is active on the phone itself.
