Why might Personal Hot-spot not appear in Settings on an iPhone?

Personal Hotspot depends on support from the user’s wireless carrier and cellular service plan. Apple specifically states that if Personal Hotspot cannot be found or turned on, the user should confirm that the wireless carrier has enabled the feature and that the wireless plan supports it. Therefore, option A is correct. Personal Hotspot does not require a 5G connection; it can operate with supported cellular data services on other network generations. Low Power Mode does not normally remove the Personal Hotspot option from Settings, and Wi-Fi Assist controls the use of cellular data when Wi-Fi connectivity is poor rather than determining whether Personal Hotspot exists. Carrier provisioning and plan eligibility are therefore the most relevant reasons that the Personal Hotspot setting might be unavailable.
