The set-up and operation is always different, depending on the browser & the system.
- Settings > WiFi > long tap on your wifi connection > tap on “modify network config” >select the checkbox “show advanced options” > change proxy to manual
- Settings > Wi-Fi > touch the i-icon of your wifi connection > scroll down > set the http proxy on manual
- In Mobile network + SIM settings, tap SIM settings > Add Internet APN.
