New Pixel 6 Pro.  Worked fine for first few days.  Now when the phone shows connected to 5G UC, I can not receive any data or connect to internet.  There's an exclamation point in the notification area.  If the phone shows just 5G or LTE them I can receive data.  Tried resetting all networks and still won't work on 5G UC band.

Having the same issues with my iPhone 12 Max. Phone turns into a brick when UC triggers. First time in a long time I’m looking for new service. Reset my network settings, cycled my phone… nothing works. Worst part I can’t restrict UC from triggering and turning my phone into a brick. 

No. The solution offered by T-Mobile was to turn off 5G completely and only use LTE… not exactly the right way to keep customers. They should have held back the rollout of UC.

Figure it out yet? Same issue on my iPhone 13. I JUST got T-Mobile about 2 months ago, and they say UC stands for “Ultimate Coverage”, but that’s gotta be a joke

Exactly! Sounds like T-Mobile is saying, go to another carrier. I still have a couple apps that get no data when UC is connected. Royal PITA 🤬.

+1 every time I see 5G UC it means not enough internet even for checking emails, I am on T-Mobile ONE, feels like punishment for being on grandfathered plan… no offers, no promos, no internet, I wish John Legere to be back so bad 

This is a terrible experience very frustrating and purposeless to have if it’s not going to work in emergencies

Having same issue with S21 Ultra. Anyone find a resolution?

5G UC T-Mobile’s “Ultra Capacity” network technically includes high-band 5G. The range of the higher bands are much more limited (1 mile radius) than mid and lower bands and some phones may not handle the higher mm bands very well. The mid band delivery makes more sense but still the 2-3 mile range and penetration could be sketchy. With the T-Mobile solution it appears the UC could appear when connecting to the mid-band mm or high-band mm network but probably the mid-band mm network. Since the radius of delivery for a mid-band mm frequency is not that broad (2-3 miles) it seems the delivery for mobile customers in transit is probably be a bit problematic. The lower “5G NR” T-Mobile solution has better range and penetration so is more forgiving. The solution seems to be more towers and more uniform coverage. It is not there yet. Just my take. 

I had this issue on my S21U once UC started showing up. This is what worked for me.

Go to device settings. Then connections. Then sim card manager. Deactivate the SIM. Wait about 15 seconds. Reactivate sim. Enjoy faster speeds.

Hope that helps.

Think I'm good now.  Believe it was a combination of cell tower upgrades in my area and sim card.  Switched to esim and getting better connections and data transfers.

I saw a post where the suggestion to resolve the data issue when seeing the 5G UC is to revert to LTE. On the 5G capable iPhone go to Settings > Cellular > Cellular Data Options > Voice & Data and then set LTE vs 5G On or 5G Auto. That should work for an iPhone. I don’t have the Android but I am pretty sure the same approach should work. Set the phone to use LTE for data when the 5G UC results in no proper data delivery. I have been there and experience the same issue with my iPhone 12 Pro. It is a bother.

Been having the same issues on my iPhone 12 Pro since it rolled out back in November. Very frustrating. Would love to have a solution as well. Got any sort of response yet, T-Mobile? It’s been a long time at this point…

I have a T-Mobile Samsung S21 5G.  Same problem.  Normal drive back and forth to my property and even my calls drop whenever my band changes to 5G UC in two spots along the highway.  UC stands for Ultra Capacity regardless of what customer service says.  I can run a speed test when on 5G UC and download at 300Mbps.  Upload at 10.  But cannot use internet, cannot text, cannot make calls.  Makes no sense.  They want you to see how fast it is with a speedtest but then block you from using it for normal purposes.  

I have an iPhone 13 and magenta max 55+ and lost data everytime UC turned on. pretty bad to lose nav data when in a different city and trying to navigate. I saw above that one person was able to turn off UC but I don’t see where that is an option. calling it ultra capacity is a joke.

I see the ‘Adaptive Connectivity ‘ on that Pixel.   you may want to check on its use.
