'Hot spot' as in Settings->Personal Hotspot? I've had that enabled for more than 10 years, and could count the number of times I've found it off and had to turn it on again using one hand. Sounds like a regional/carrier-specific thing. I recall that in the early days, carriers could disable hotspot functionality on their network. I hear hotspot functionality is pretty broken on iOS 26 though.

GP’s behavior is what I see, it usually doesn’t shut itself off while I’m connected but once it’s on I have to act fast to get connected or it’ll shut itself off in a minute or two. And if I disconnect for a second, it’ll be off and I have to turn it on again. Really annoying the rare times I use it.

Been like this many versions, but dunno if it does it with the latest.

It sure what’s going on my side. Hotspot turns off almost as soon as there is no usage. I wonder if there is a way to debug that.

Just checked I’m on iOS 18.2.
