Setting up hotspot

To set up the hotspot feature on the iphone go to settings,

then select general,

select network,

the hotspot feature will check if the phone has the feature enabled,

once the phone finishes its check, (if the feature is enabled) you can turn it on and select the network name and password

and if the hotspot is not enabled it will display a message like the one shown and give the option to call your carrier to enable the feature or view the carriers website for more details.
