I have been having the same problem on and off for a few months and it is about to make me switch carriers. I finally found someone who understands what I'm going through and describes it well! I have an LG velvet that I've had for 1.5 years and I had no problems until the last few months. But my problem happens whenever I leave Wi-Fi and go to mobile data, or when I'm on 5G and then I go out of 5G and try to go to 4G. Everything shuts down. It shows me I'm still connected so I've been unaware, only to find out that there's a bunch of texts people didn't get from me that I thought went through, and there are texts that I'm not receiving. And on occasion I've tried to make a call during this time and it won't call out. When I restart my phone it's fine. But it happens frequently and I need this fixed! I have five other people on my phone line but none of them have 5G except me. None of them have problems. So are we pretty convinced that it's a T Mobile 5G problem? I've been with T-Mobile since 2006 but I run my business from my phone and I can't function like this. Even when I leave my phone on LTE all the time it still happens. Have to constantly restart my phone or turn airplane mode on and off. I'm never really sure what's working to fix it. Does T-Mobile text see this thread?

Honestly it does sound like a device glitch on the iPhone side. I have an iPhone 13 Pro Max and running on the 5G in my area,  ever fall from 4 bars and still I get CB glitches. I have the T-Mobile 5G home internet and when I  run the wifi through my iPhone, Voila, internet is Super fast. 

I wish I had something different to add but, I’m just confirming that I have the same issue and am thinking about switching back to Verizon. I wanted to love t-mobile but just isn’t usable. Like all of you, great signal but no ability to use data.

That's pretty much a nice way of stating iPhone 12/13 doesn't always work well with 5g NSA

FWIW - Here is the response I received from T-Force when asking about the issue. The funny thing is, 5G coverage in my town is honestly pretty good with UC covering a good chunk of town. I don’t think lack of coverage is to blame and I am interested to know about this special iphone 12/13 network she referenced :) Realistically, it’s probably a N71/LTE blending issue.

 

“It's important to have all the details you need to know about our 5G service. I'm here to help! We have a new 5G service that we're prepping called stand alone 5G for the iphone 12-13 series. This will allow your phone to operate even if there is only 5G signal in the area. We currently don't have this service available in your area quite yet. We do have a 5g tower in your area and at the moment you should definitely be able to see 5g outdoors and in most homes (depending on your location) but the LTE signal in this area is quite a bit stronger at this time so it's likely your phone will opt for LTE for the best experience till we add additional 5G spectrum. To why I suggest on you turning off the 5g from your device till we launch this software. Our 5g network is still maturing and we look forward to providing more 5G coverage as our journey continues. You can always keep an eye on our network newsroom here: https://www.t-mobile.com/our-story/network-and-innovation to stay up to date with our integration plans. Meaning you will experience some issues with lagging, call drops, messages not sending nor receiving, data issues till we launch this new software to our iphone 12-13 series. I would suggest to turn off the auto 5g connect and connect to LTE/4g as the signal is much stronger. If you want to go ahead and give this a try after restart your device please”

If you're willing to test the waters…to disable n71.  menus are slightly different on each Samsung model...this is from S21

I can't speak for the ultra, but on a S21 in many areas, I've either disabled 5g , or disabled  n71 SA/ n71 NSA due to it being either saturated on SA or ‘the weakest link in a chain’ on NSA.  eg.  1Mbps on ‘auto 5g/4g/3g/2g’, and 60 on 4g/3g/2g.   if I went the route of  disabling n71, but leaving n41 enabled, I get 400Mbps.

Exact same issue as all others have described. S21 Ultra. 

TMobile wtf? 

How bout an explanation by now?

This is quite frankly the only issue keeping our switch from Verizon to T-Mobile from being great. I’ve been impressed otherwise by not seeing any drastic reduction in coverage vs Verizon. T-Mo also has. better UWV presence in our area than the competitors and it’s pretty fast - when it works.  However, all that said, I am about to lose my sanity and jump to another carrier.

 

I spoke with support last week only to be told that I should consider turning off the 5g on my iPhone to fix the issue. I didn’t switch carriers to the “nations best 5g coverage” to turn off my 5g.

Happens to me all the time … shows it have bars and LTE but no data connection… dealt with this for a while now … switching to Verizon seems it might fix the problem

I landed here while googling for help on the same issue. Nothing to add other than happens to my wife and I daily on our new iPhone 13’s with T-Mobile. Stinks, because otherwise, our decision switch to this carrier has been been okay and the network is definitely fast when it works.  The issue seems worse when leaving wifi going to cellular data but it also happens randomly when out and about. In all situations, full signal, no data.

 

I just got the new Moto G100 and I am having this exact issue. Maxed out 5G signal, but it's running like it's dial up. Slow if it works, with repeated dropped signal. Irritating is an underwhelming statement.

This is happening to me constantly on an iPhone 12 Pro running iOS 15.1. It happens when I leave my home wifi. It happens when I’m driving and need to access Google Maps, among many other situations where I need data. Google Maps will say “poor connection” or not even appear to have a connection at all, yet my phone has full blown 5G service. Toggling airplane mode usually fixes it, albeit temporarily. Sometimes it only fixes it for a couple minutes. When it manages to fix itself I get a slew of notifications that are finally able to be pushed through. 
 

It’s extremely frustrating. I have 5G in most areas, most recently 5G UC. I live and work in a major city and I almost never get a signal below 5G. I switched to T Mobile and initially loved their service, but this is frustrating to no end. Resetting my Network Settings is becoming annoying at this point and is not an acceptable solution anymore. 

I had this issue for a year with my iPhone 12 Pro (I simply dealt with it, switching airplane mode on and off to reset the connection) and now with my iPhone 13 Pro. This morning I took my dog out and found I had no connection the moment I left my house’s wifi. And I can tell you for a fact that there is literally a T-Mobile 5G microcell within 300 feet of where I was standing, basking in solid full signal, and no data connection whatsoever. This happens nearly daily to me, or at least seems to when I manage to catch it.

I find it happens in the vicinity of Ave U in Gravesend, Brooklyn. No one can hear me. It goes out. Unfortunately, it happens in my house and I can’t live this way since it is my only telephone. Anyone in that vicinity?

I am also experiencing this issue; it started around September 20. I even did a Factory Reset on my Z Fold3, but it didn’t make a difference. 

My co-worker also has T-Mobile, we sit in the same area, but he doesn’t have this issue.

Has T-Mobile find a solution yet?

if someone else with TMO is right in front of you and they are not in any way or form connected to your account and their service is fine then its an issue with either your phone or something with your account.

Perhaps you are correct; I have already replaced my phone. Another line in my account is also experiencing similar issues. 

Thanks for your comment.

I also experience this issue randomly throughout the day. Hopefully there is an explanation and solution to this.

I can say for the iPhones, but in my experience with Android, and Samsung/Oneplus and LG, 5G “extended range" can sometimes make service worse.  I've actually gone and disabled n71 on 5g as it becomes the weakest link in a chain, especially when 5g is coming from one tower, and LTE is from another.  Depending on your area, you might not have 5g “ultra capacity” for use, which would give you LTE only.

Did anyone ever get this figured out?  Has been happening to me for a long time on multiple iPhones, including my brand new iPhone 13 Pro (and my iPhone 12 Pro before that). It doesn’t happen to other family members, and it’s bad enough that I’m starting to look at what options I have with other mobile providers (not a threat, I’m just at my wits end…)

did you attempt to change it to 4G instead of 5G in case its an issue on the 5G side of things?

I’m having the same issue with my S21 Ultra. I can be sitting in my living room and have 5G w/full bars and it will not allow me to use any apps or internet through chrome. States, Offline. Place it in Airplane mode and back off and it works again. What gives? OP were you able to figure out the issue?
