Can't receive data when on 5G UC

Hey T-Mobile - not cool that you ignore this conversation. You have users struggling here, and we'd love some participation from your engineering staff to get it figured out and resolved!

Same problem for about the last two months. 5GUC doesn't give me enough bandwidth to use Instagram. Thinking of switching networks just as I was about to get a new phone / contract. 

Any resolution? Just moved from Verizon to T-Mobile, and 5Guc turns my iPhone 13 Pro into a brick. So frustrating. No help from the TMobile stores.

Any resolution to this issue - I have this same problem using and iPhone 15, works with LTE and regular 5g but when 5g UC is on the phone would be more useful as a decoration in my fish tank.

I am having no data when I see 5G UC

Hola all,

Is this data stalling issue on 5G still happening to you guys?

Any improvements recently?

It has certainly gotten better late this year for me, I can keep 5G on pretty much all the time.

There are blips where it's noticeably slow, like ping, not download speed, even with 100% bars. But I don't have the roaming problem anymore where it seems like it's not connecting to the next tower when I drive somewhere and I'm dead in the water with 5G UC showing.

This is a relief to see that it’s a widespread issue - and so unbelievably disappointing the casual and consistently careless response from T-Mobile.

So I'm in Northern Virginia, I got an iPhone SE 2022 (from T-Mobile) and Magenta MAX. In fact (and this was all discussed in detail at their store, with total reassurances that it would all work), a PSIM from T-Mobile LTE (work line, for calls only) and eSIM with Magenta MAX for personal call and "unlimited" data.

From the start, the same problem highlighted on this thread on different brands, different models: at 5G, lightning fast speeds. But the moment it goes to 5G UC (which it *always* does, automatically), it's a brick. If I use the work line (LTE) for data, it becomes normal. If I use the Magenta MAX line and turn off 5G, it also works normally in LTE.

Customer service… Geez, I just feel lied to. First (after making you do all the obvious dummy "fixes" that never work) they said there was some construction going on and it was going to get better. It didn't. Then when I pushed hard with facts, speed test results, they buckled ("yeah we have identified this issue with the iPhone SE 2022 model in eSIM"). A lie, as here we can read cases from different models and brands. Their solution? Turn off 5G for good, as speeds are "very similar". Did they get trained to really recommend that? (In the posts above I conclude that… yes, it's a standard answer).

Last straw for me: we are now moving to a new location. We go to the T-Mobile "coverage map" to check: and the entire street we are moving to (I'd say every single area in Northern Virginia in fact is showing like this as well) shows as a solid FULL coverage for 5G, 4G, everything. I go on the street (outside the house!), it's ONE bar. One bar on LTE, one bar on the useless 5G UC. So choppy and sluggish even when on LTE. Inside the house? Nothing. No data. Voice calls ridiculously choppy.

I guess Verizon it is then for my personal line. And a big push for my company to drop T-Mobile for the business line provider as well.

I came for the same reason. I just switched to t mobile yesterday and right away noticed 5G UC means my connection sucks. On S21 Ultra + . I need to ask my wife about her phone but assume it's the same since it's the same type of phone we both ported over from Verizon. When it goes to regular 5G it sends "normal" but once UC shows up it's pointless to try.  I tried some of the things above and I'm on a physical sim but so far nothing concrete.  I'm going to try that airplane mode thing, years ago I had an S5 that needed that trick to work.

I also want to add to my note above is that I have new devices. New LG tv, desktop and iPhone 14. It is not my devices.
