Can't receive data when on 5G UC

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.

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 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.

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 wish that were the case but neither device is on e-sim or dual capable and on separate lines. TabS8+5G has new sim and had them send new one for Note 10+5G since the original was over 2 years. Not sure about tower modernization either since it's been this way over a year but even worse the last couple months. Tech says nothing going on with towers in this area and with the coverage they see it doesn't make sense. New Tablet vs older 5G phone shows minimal speed difference but going for the S22 Ultra to test because of better 5G tech inside. I can detect mmWave signals but it's not off of my tower which is a tease but do get 4+bars 5GUC on tablet all day long. I know I can get slightly stronger data signals on 5G bands out here but band selector cannot lock them in. Phone steps in and constantly forces me back to band 2 and 66 which are always the weaker signal. Going to test the Hi-boost 10k pro signal booster to see if it makes any difference in data on the LTE signals out here. If I can get - 80 to - 100dbm at least it would be better than - 100 to - 120dbm.

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 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.

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. Sorry but with technology has going pains.
