On your Android phone, open the Datally app.Tap Track hotspot on the home screen.Enter your data limit. You can limit your usage in MB or GB.Tap Go to Settings.Tap Hotspot & tethering.Enable the Wi-Fi hotspot.Navigate back to the 'Track hotspot' screen in the Datally app.Tap Track hotspot to begin monitoring your data.
