Does 6s-32gb come with a personal hotspot?

The size and model has nothing to do with the Personal Hotspot availability.

Its up to the cellular carrier you choose and the service plan you have with them that determines whether Personal Hotspot is available or not.

Contact your chosen cellular carrier and ask them what plans offer Personal Hotspot on an iPhone.

That would depend on if it is offered by your chosen cellular provider, and if you purchase that option from the provider.

Glad I could help.
