Oppo: Share Internet Access via Bluetooth

Bluetooth internet sharing on Oppo phones routes the connection through your mobile data plan, not through WLAN. If WLAN is active on the sharing phone or on the receiving device, the Bluetooth tethering toggle often stays greyed out or simply does nothing when tapped.

Turn off WLAN on both devices first, then pair them over Bluetooth if they are not already connected. Once paired, open Tap on Settings ➔ Tap on Bluetooth ➔ Select a Paired device ➔ Enable or disable Internet Access to switch the sharing option on for that specific device.

This only works one paired device at a time, and the option appears per device in the paired list rather than as a single global switch. Speeds are noticeably slower than WLAN hotspot sharing, since Bluetooth bandwidth is limited, so this method fits light tasks like checking messages or loading a simple webpage rather than streaming or large downloads.

If the other device still cannot browse after enabling internet access, confirm your Oppo phone itself has an active mobile data connection and that data saver or a data limit is not blocking background traffic for the Bluetooth connection.
