Connecting to internet via hotspot on iPhone

Hi, the place I work at doesnt allow us to use wifi so I use 4G LTE on my iPhone. I’m trying to connect my radio through the hotspot option on my iPhone but it doesnt connect? The network shows up and I put in the password but doesnt connect to it.

I tried with a family members phone. Used a samsung with the same 4G LTE network and its hotspot. The radio connected just fine with it and I had internet.

So is it just an iPhone problem? I dont really want to get another phone or hotspot device just to have it connect to it. Any help is appreciated. Thanks.
