SOLUTION! SOLUTION! SOLUTION! Well, I had the same problem, went to Apple where they told me to backup and reset the phone. I won't starting to that procedure so much, so I decide to search for a solution on the net. I find a lot of things, as resetting network setting, turn on and of flight mode. change and check setting for the cellular network etc. etc. nothing worked. As least I readed something about, taking your simcard out (fysically or re-install e-sim) to solve the problem. And guess what!! PROBLEM SOLVED :) I can connect my non-APPLE devices again :) So just try- No you have YES you can get :) Have a nice day! ;)

since the update of IOS 15 he hotspot is not working. My colleagues have the same issiue, the ones who didn't update (they use 14.8 IOS) they can still connect to the Iphone hotspot with non apple devices. Apple has to bring out a fix quickly. this is not acceptable. I updated a fix for some other issues today (05-10-2021) but the hotspot problem is still not fixed. it's a WPA3 encryption problem probably, but it has to work backwards with WPA2 also. so fix it please. Please hurry up.
