If this is the first time you have used a Personal Hotspot on your phone, you will first need to activate it by tapping 'General', 'Cellular', 'Personal Hotspot' and switching it to 'ON'. Next time, you’ll see 'Personal Hotspot' in the settings menu.
From the home screen, select 'Settings'.
Select 'Personal Hotspot'.
Set your Personal Hotspot to 'On'.
Once it's active, you can choose a password for your Personal Hotspot by selecting 'Wi-Fi Password'. We highly recommend you set-up a password to protect your Personal Hotspot from unauthorised access.
Pick a password that is a minimum of 8 characters, then select 'Done'.
To turn off your hotspot, follow steps 1 to 3 above, changing the setting to 'Off'.
