A Personal Hotspot lets you share the cellular data connection of your iPhone or iPad (Wi-Fi + Cellular) when you don't have access to a Wi-Fi network.
Set up Personal Hotspot
Go to Settings > Cellular > Personal Hotspot or Settings > Personal Hotspot.
Tap the slider next to Allow Others to Join.
If you don't see the option for Personal Hotspot, contact your carrier to make sure that you can use Personal Hotspot with your plan.
