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.
You realize right the cell spot works off your internet. If you have bad internet, or you live next to a bunch of people with tmobile, and bad internet its not gonna work. That cell spot shares your internet connection with every one, and they can travel quite a distance. When I had mine on the roof it went over a mile. I have a note 10 x2, s 20 ultra, razer phone 2, Sony Xperia, and a s9 and they all work fine. Mind you I have fiber internet and no one lives next to me.
Adding in it isnt gonna work right if you have slow internet, and some one is using the internet. If you are maxing your upload or download speed of your isp, it is going to add 300 to 2000ms ping to it, adding in lte is already slow. My ping from my wifi 5ghz is 11ms, my ping from the 4g lte cell spot is over 40ms. My computers ping is 10ms. So if your normal ping of your internet is low end like satlite, bad cable, dsl, or any low end internet like that, then trying to add a cell spot isn't gonna work at all. Especially if other people connect to it, and you won't even know if they are connecting to it or not. Then add in anything some one is doing, say Netflix which if its Mac is like 28 mbps, YouTube can be around 15mbps.
One thing you can do is go to settings turn on developer mode, go into those settings and make it so 4glte is always on. Also if you have a actual t mobile signal there what you want is a cell booster not a cell spot.
T mobile doesn't give you cell boosters, they give you a thing that leaches your isp and turns it into a 4g lte wifi singal. A 5g cell booster will cost like 560 bucks for the low end one, if you want to cover an entire house you would need a more expensive one. My honest guess would be the note 20 is getting confused by which signal to hook to, so you would have to manually tell it in your settings.
