Can't receive data when on 5G UC

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

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

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. 

Have you tried using Samsung Band Selector? It's at Play store. You can choose the bands you prefer and just keep the UC bands out. N38 and N41 are mmWave, N260 and N261 I believe is where the UC starts. When I can lock these 4 in I can get better data speeds than on the regular 5G bands. Unfortunately when I do get the better bands the phone eventually will switch me back to the shittier band 2 and 66 for some reason except for on my Tab S8+5G which loves the UC and mmWave. 

I had a similar problem come up in the last month and a half. I'm on an iPhone and was running iOS 15.6, and 15.5 before it, when I stopped receiving texts intermittently. Sending always worked.

I narrowed it down to 5G; if I was on 5G, texts would stop. On 5G UC or LTE, they'd come through.

Restarting seemed to help, but in the end, what’s worked 100% of the time was removing the plan from my phone entirely, then I reactivated it.

Now the phone seems to join 5G UC and WiFi calling more often, receiving texts just works, and I’m still using the same eSIM as before.

Hi Jimmy, what you are experiencing is a sim issue, it's unfortunate right now with all the modernization of the towers,  but rest assured there is a fix.  You'll need to switch from the esim to psim (physical sim). We've noticed this issue with all Apple Devices with dual sims. If you're device doesn't have a physical sim, just drop by aT-Mobile retail store and pick up one.  They will be happy to make the switch for you.  No need to use it for a paperweight.  Hope this helps.  

Not on Apple device and no eSim. Been on physical Sim card and recently changed Sim cards since I've had the original for 2 years. Made zero difference. CS, TECH and Force team have not been able to fix or even have an answer as to why only my data is affected. It's not my phone, I recently switched from Galaxy Note 10+5g to Galaxy S22 Ultra 5G and nothing has changed. Everything is great except data. Switching from 5G to LTE might make a 0.10mbps difference so in other words nada. It's really disappointing paying for their highest plan with unlimited data and not being able to use it. No answers, no explanation but I continue to pay the full amount. I've done some checking and my signals separate from bars since they aren't very accurate are typically - 90dBm to - 120dBm. I purchased a Booster which is disappointing being on the highest plan and have to resort to spending up to $600 for a Booster. Did some experiments. I can get my signals as good as - 50dBm and from what I've researched that should have you at awesome speeds. That's about as good as levels typically get. Nope, sometimes I can get maybe 1mbps but it typically always drops back down to 0.50mbps. Now what does improve is the upload speeds. With Booster I can typically hang around 20-30mbps. That's great but does me little to no good because I need download speeds. Why good UL and no improvement on DL, I have no idea. Like T-Mobile has pretty much said, oh well, sucks to be you. What else is new.

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. 

I've tried speaking to every department multiple times, T-Force, Note 10+5G with 4 solid bars to Galaxy S22 Ultra 5G 4 solid bars 5GUC 4 bars LTE extended and my data is a consistent 0.50mbps. I got so desperate I purchased a signal Booster. $500 and achieved up to -50 to -65dBm which is a very strong signal. I think that's about what the phones go up to. DL speeds sometimes 1mbps but always settles to 0.50mbps or worse. But UL speeds go to 20-30mbps which is great but I need DL not UL speeds. Makes zero sense to me why up is good but down is not affected. Not even T-Mobile or their techs can give me "any" answer. No clue but they're still happy to get my monthly due.

Hey Scott, you can read my update above but I do wonder what you mean by "removing the plan from your phone". What does that mean and do you know how that affects your phone? Just curious, never heard anyone say that. Thanks in advance.

Hola Jimmy,

No problem. So, in iOS, go to the Settings app, tap on Cellular, then in the "T-Mobile" section, tap on "Delete eSIM". You should be prompted to remove it (and it should say something about removing your plan) from your phone.

Give it a reboot, and if you go back to Settings, then General, you should see your EID, and at that point, the phone can be re-activated, though to do so, you may need to go to a store.

I’m having the same issue with my iPhone 13 pro -  no connectivity on 5GUC had ti change the data settings to LTE.

Do we know the root cause of the issue?

might be the area.  I have no issues with 5g uc in my area.  in fact, my phone (S21) often ends up on N41 SA (no LTE) often where I am.

Had same issse this AM and had to switch to LTE - note the new carrier settings in iOS 16 don’t affect the problem.
