I have an iPhone 6s with an unlimited data plan. I want to turn it into a personal hotspot so that my kids can do homework on my MacBook Pro while we drive. The directions on the internet did not really help. It showed a "mobile " setting which I don't have for my hotspots setting and under personal hotspots setting all I have is a directive to a link to the general Verizon website which is not helpful. I know that both the phone and computer are set up for easy links for this. How do I do this? I have an unlimited data plan. So that should not be an issue either. I just need directions to make the hotspot happen. Please help.
