Can't receive data when on 5G UC

I am on T mobile home internet. It must switch to 5Guc 20 times an hour at times. When this happens none of my home devices work or connect to Wi-Fi.  It will be impossible to work from home.  I have called T-Mobile support many times.  They just run through the same reset procedures.  I am very disappointed as I wanted to give T-Mobile a go.  They offer no assistance or solutions. It is clearly happening to others as well. 

Having same issue.  At time I see just 5G and it is fast, as soon as I get 5UC it craw’s sub 1mbs on the speed test .

Called suppoert, 46 minutes later they said it might be a problem with my "OLD PHONE".  I have a ZFlip 4, 

My data is super slow all the time. I'm so mad I could spit! I'm probably going to change to another phone company because of it. This is absolutely ridiculous.

I purchased S22+ today with Note 20 5G trade in. The speed on S22 is very low.Like 4g low.  Note 20 was working fine . So I did a chat and we spent about an hour troubleshooting the network and the phone. Changing settings,restarting,turn on/of some stuff on the phone Nothing helps.  Note 20 doesn't have any "UC" on display and provided 150-250Mb on the speed test. S22 do has "UC" and gets between 10-20 Mb. CS thinks there is a network outage in my area but this affected only S22 but not older 5G devices.

i was replying to the 3pm-5pm post right above mine.

so for you its happening at peek hours..usually means they are either in process of working on said towers and upgrading them or they are still in need of said upgrades. the towers you are connecting to at those hours are over capacity at those times due to how many people are on them.

I don't think it's happening at peak times, it's happening all day for me regardless of time. My job requires me to be on my phone with calls all day especially since I have to check satellite sites. The issue is on going all day. For me, anyways!!

I recently moved to Magenta Max with 14 pro max. Whenever the phone shows 5G UC there is hardly any data. The speedtest fails. I did the trick of turning off 5G and moving over to LTE and it seemed to work but then what is the point of paying for 5G.

Also, I noticed it happens severely during 3PM-5PM when school dismissals are happening. I am in Houston, TX suburb.

Anything else I can do, I am guessing I already have the highest plan and the latest 14 pro max. Customer Service does not have any clue about this. 

This has been going on for so long. At this point I have no other option but to go elsewhere for cell service. T-Mobile 5GUC service reminds me of dial up.

Why only my phone? 

If you are getting a solid 5 bars 5gUC, then I've had the same issue at times: congestion (i.e., near a ball game).  Anything less than 5 bars, 5GUC suffers tremendously (your phone can see it but the tower is not hearing your phone).

 

My solution, unfortunately, has been to disable 5G altogether,

I'm in the Kansas City area. This past week I've had the exact problem with 5G UC. Just came out of no where. I turned Sim off, waited, then tried, nothing. So I went back and changed automatic 5g and im using automatic lte, and my phone is working fine again. I have s21 plus 5g.
