Hi Srbhyuvraj,

You could follow the Apple Support Article to turn on the personal Hotspot.

Have you ever used personal hotspot? If not, you need to find out if your carrier support personal hotspot feature.

As Juitse tried to explain, first you need to be certain you are using a cellular carrier that supports personal hotspot. Not all carriers support it.

Next, you need to be certain you personally have an account with your cellular carrier that supports hotspot. Often carriers charge extra for this service as it involves using extra cellular data.

(For some carriers, they would need you to fill some APN information in "Settings"-"Cellular".)

Hi

Go to settings Cellular personal hotspot below mobile data

Your network provider should have enabled this.
