Unstable Hotspot and MMS Issue

Hi All. I am having a strange and annoying issue. I have an unlocked Samsung S21. When I use the APN provided by T-Mobile, I have a very unstable phone hotspot. I turn on the hotspot; sometimes it connects, sometimes it doesn’t. If it connects, it disconnects quickly. I have to turn on and off airplane mode multiple times to get it to work. 

I found a work around by creating a new APN for the phone. I changed the APN Protocol to IPv4/IPv6 and the APN roaming protocal: to IPv4/IPv6. With those settings, the phone hotspot works. Great right? Almost. Unfortunately, with those settings, I can no longer send group MMS.

And to make matters stranger, my wife has an identical phone without hotspot issues.

Can you help please? -Thanks!

    My hot spot issues were resolved after a hardware update pushed through by Samsung.

    My iPhone hot spot works on my iPad and iMac but drops after a short time or if I walk away a few minutes. How to keep it on as our internet service is poor in some parts of the house
