How can I set up Wi-Fi on kiosk devices?

If you set up kiosk devices for another site and know the Wi-Fi SSID/key at that site, you can add the Wi-Fi network in the Wifi Configuration option in Fully’s Device Management settings. The device will then connect to that Wi-Fi network automatically. Note that on Android 10+, this feature works silently and reliably only with provisioned devices.
If you don’t know the Wi-Fi credentials, you can set up a special Wifi/Settings PIN in Kiosk Mode settings and give this PIN to the administrator on site. When entering this Wi-Fi PIN instead of the Kiosk PIN, that person can open the WiFi Settings and connect the device to the network without being able to exit the kiosk or change Other Settings. Be aware that this feature can break the kiosk on some devices (like many Samsung tablets), as they allow access from WiFi Settings to all other Android settings. In this case, please try to use the Select Wi-Fi Network option (for Android 10+, this option works only on provisioned devices) or put the following Android Settings activities onto the App Blacklist.

com.android.settings/.Settings
com.android.settings/.homepage.SettingsHomepageActivity
