Major network issues on Note 20 ultra with T-mobile network and Cellspot
I live at the edge of T-mobile coverage on a hill. T-mobile provided me an LTE cell spot for years which worked fine with my Note 8 for the last 2.5 years. I bought my Note 20 ultra on September 6. ...

Make sure you are using the new 5G sim card included with the device. It says R15 on the chip if you want to check it.
I’m using the R15 SIM .
It looks like the problem is with the Note 20 Ultra. A software update came in that broke it in October. A second software update just hit my phone this week, but it didn't fix it.
T-mobile told me to try with another phone. I ordered an LG V60 thinq dual screen, which I received today. It has no problem with the Cellspot.
At this point, it looks like only the original firmware for the Note 20 Ultra worked with the Cellspot, and nothing else afterwards does.
I don't have a reliable network at home without Cellspot. I will ask T-mobile to buy back our Note 20 Ultra as they no longer work on the cell network we have at home.
Advance support wanted me to exchange the Cellspot for a 3rd one. I declined, as the first 2 behaved identically. They told me the next step was to consider switching to another carrier ! I asked for a ticket to be filed . They told me to keep the Cellspot on for 3 days while the advanced support team investigates. That's 3 days during which we won't be able to make calls (Wifi calling not stable enough for calls; texts are OK after I enabled a Wifi calling compatibility setting in the Signal app).
