I had iPad 2 iOS 8.1.2 and I can not find the hotspot in my ipa

Hello Dr.Hossam,

It sounds like you have a fully updated iPad with a cellular data plan, but do not have the option to enable Personal Hotspot. I would recommend you take a look at the troubleshooting in the following article, named:

iOS: Troubleshooting Personal Hotspot

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.

Thank you for using Apple Support Communities.
