Hotspot Tethering is NOT ALLOWED for AT&T prepaid phones?

Whether or not you have the ability to use your hotspot is determined by the plan you have purchased not the phone and not whether you are prepaid or postpaid.

The prepaid $30 5 gig plan you can tether all five gigs if you choose. The $40.15 gig plan you can also tether all 15 gigs if you choose. There is a $300 one-year plan which provides 8 gigs every month, also fully available to tether if you choose. The $65 unlimited plan, before any auto pay discount, does not include any Hotspot data but can be purchased as an add-on. The $75 Unlimited Plan, before auto pay discount, includes 10 gigabytes of hotspot already.

Thanks for your prompt reply. I'm getting multiline and autopay discount with my family members. Maybe that's why. I don't need hotspot a lot. But it looks like I need to choose separate plan from my family members to use tethering function. Thank you.

No, not true.

It doesn't matter if you are in a prepaid multi-line group or that the group is getting multi-line and auto pay discounts.

The only thing that determines whether or not you can use your hotspot is if you have a plan that allows hotspot use. I have already listed the plans in the earlier post.   If you signed up for the regular unlimited plan, that is $65 full price, you don't have hotspot. 

If this is something you need or want you will have to change plans.
