hot spot not working on iPhone 6 after ios8 update

Hey there lgpagan,

It sounds like you are not able to use the Personal Hotspot function on your phone after updating to iOS 8.0.2. I would recommend the troubleshooting from the following article named:

iOS: Troubleshooting Personal Hotspot

Basic troubleshooting

1. See if your iOS device, computer, and wireless plan all meet the system requirements for Personal Hotspot.
2. Make sure Personal Hotspot is on: Tap Settings > Cellular > Personal Hotspot.
3. Check the Internet connection on your iOS device: Tap Safari and load a new webpage.
4. If one connection type doesn't work, try another. For example, instead of connecting using Wi-Fi, use USB or Bluetooth.
5. Turn Personal Hotspot off and on: Tap Settings > Personal Hotspot or Settings > Cellular > Personal Hotspot.
6. Install the latest version of iOS.
7. Reset your network settings: Tap Settings > General > Reset > Reset Network Settings.
8. If you still see the issue, restore the iPhone.

There is additional troubleshooting in the article if the above does not resolve the issue.

Thank you for using Apple Support Communities.

Regards,
