My phone does not have a personal hotspot option

The Hotspot is a Carrier Specific feature. Contact your Carrier (Cellular Service Provider), the agency that issued the SIM / eSIM to you.

See the Pic below the Hotspot is made available based on the Mobile Data selected and the feature that is enabled by the Carrier

The Hotspot option and service is provided by your carrier......the guys that you pay each month for your cell service.

Tap Settings

Tap Cellular

If you don't see a Personal Hotspot option, your carrier does not offer this service......or......they may offer it as an additional option that you can add for an additional fee each month.

Contact your carrier to find out what they can do for you.
