I've had multiple trouble tickets for the issue that I can't get our brand-new iPhone X's to function as a WiFi Hotspot flawlessly at all locations. Mine has the unlimited bandwidth and my wife's is throttled at ~500 Kbps. However, the symptoms are identical.
At home, we had OK 4G LTE (1-3 bars) and can get up to 15 Mbps data up or down. However, it will NOT allow a remote device to connect to the Personal WiFi Hotspot running on the iPhone X and the error messages vary from 'Incorrect Password' to 'Tethering device may be too far away' (or something like that). For the extreme rare occasion a connection is made, the bandwidth on the client device is unusable.
Now what always works is USB tethering! Then we get the full speed we are paying for. So why should WiFi be different???
When I change locations (and therefore towers), there is a 50% chance of it working in my area (Nashville metro). If it works, it always works great at that location, if it doesn't, it never works!
Don't know if this is related (shouldn't be), but the only towers near my home are 700MHz (Band 12) only. Could there be a connection?
Has anyone else seen this phenomenon? I.e., WiFi HotSpot being location dependent, but USB tethering not?
Needless to say, I'm extremely frustrated as this appears to prohibit my primary motivation which is to use the iPhone hotspot as the primary source for my car to get it's Internet connection rather than paying yet again for another SIM card for the car.

I'm 100% with you that this is location based as that's the only thing that makes sense IMO. It's an incredibly odd and uncommon scenario but I'm sure with all the proper info, our Engineers can figure this out.
