No hotspot iPhone 6

Hi there Pushkarkokane,

It looks like you are missing the Personal Hotspot in your Settings. I would check out these steps from the following article:

1. Contact your carrier to make sure that they support Personal Hotspot, and that it's turned on for your wireless plan.
2. Make sure that 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 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.

Thank you for using Apple Support Communities, let us know how that goes.
