First, read the English article below.

"Tethering" refers to the ability to use your smartphone's cellular data as a Wi-Fi connection on a computer. Not all carriers allow this feature, though many carriers will unlock tethering on your smartphone upon request (and, in some cases, a small fee). The easiest way to ensure that your smartphone allows tethering is by calling your carrier and asking. To do so:   iPhone - Open Settings, tap Wi-Fi, and tap the green "Wi-Fi" switch.  Android - Swipe down from the top of the screen, long-press the Wi-Fi icon, and uncheck or toggle off the "Wi-Fi" entry. The rectangular USB 3.0 side of your smartphone's charger should plug into one of the USB ports on your computer. If you're using a Mac computer that has Thunderbolt 3 (USB-C) connectors, you'll need a USB 3.0 to USB-C adapter in order to connect your charger cable to your Mac. Plug the other end of the charger cable into the bottom of your iPhone or Android. This will vary depending on whether you're using an iPhone or an Android:   iPhone - Open Settings, tap Personal Hotspot, and tap the white "Personal Hotspot" switch.  Android - Swipe down from the top of the screen, tap the Settings icon, tap More below the "Wireless & networks" heading, tap Tethering & portable hotspot, and check or toggle on the "USB tethering" option. On most computers, your smartphone's connection will immediately be prioritized due to its Ethernet standing; if not, click the "Wi-Fi" (Windows) or (Mac) icon and then select your phone's name. Unlike wireless tethering, you won't have to input your tethering password (listed in the tethering menu) to connect to your phone. Since you're connected to a cellular network and not the Internet in your current location, you should be able to bypass any restrictions in this way. Keep in mind that tethering consumes a large amount of cellular data, meaning that you may incur charges on your bill if you download files, stream video, or browse for too long.
