Personal Hotspot Not Showing on iPhone 4S

On my main settings screen under Airplane mode and Wi-Fi, Personal Hotspot wasn’t showing so I just assumed my carrier (Virgin Mobile Canada) was blocking it. Turns out the reason it wasn’t showing was it wasn’t turned ON under Settings->General->Network->Personal Hotspot. Once I turned it on, it showed up on the main settings screen.

It’s available via USB, Wi-Fi and Bluetooth.

Sorry I doubted you, Virgin Mobile.
