Step #1. Open Settings → Tap on Cellular
Step #2. Now tap on Cellular Data Network
Step #3.Under “CELLULAR DATA” enter APN
Step #4. Scroll down to the Personal Hotspot section
Step #5. In the APN field, enter the same APN that's listed under Cellular Data
You can ask respective APN to your service provider or simply search in Google “Your Service Provider Name” + APN.
In some cases, you may have to skip the APN and just enter some name in the username field below it.
Go back to Settings and you should now see Personal Hotspot.
(Alternatively, quit the Settings app and then reboot your iPhone/iPad. Then check the Settings.)
Sometimes, this might not work. In that case, there are three options that you can resort to:

#3. Reset all settings – Settings → General → Reset → Reset All Settings → Enter Passcode to confirm
#4. Restore your iDevice (via iTunes.)
