Very interesting! I'm on a budget mobile service provider (Cricket), and only recently discovered that they disable using my phone as a hotspot on my plan.
I called them up, because I wouldn't mind paying a small amount extra every month to have that ability. However, they told me that they actually couldn't provide it with my phone even if I paid, because they didn't support my phone (Pixel). Then they tried to upsell me on "compatible phones"...
I used this phone as a hotspot with my previous provider, so I know it can be a hotspot. But I don't know much about the technical side of this. Does anyone know if what they're saying is plausible? (Ie, they can't offer it for my specific phone)
I briefly tried a few apps for this purpose, but none of them worked.
