Good signal/bars but no network connection many times daily

Experiencing the same. Never had a problem at all with tmo for 5 years. Ive used the 5g home Internet box for about a year or so, and speeds often exceed 300mbps. I came home from work on 08/19/23 to find that the the wifi quit working for the first time ever. Went to Google it, and my phone's data didn't work either. It's now the 22nd, and it hasn't improved. It works sometimes, sometimes it doesn't. The wifi box works for 10 minutes after a reset. The phones on my plan work for 10 mins after switching airplane mode on and off. The data loads perfect if you're on a phone call. The data works fine everywhere but my house. Got all the generic responses from cust support. The people in store couldn't help. Phone bill is paid. Came to this thread looking for answers, only found that out that I need to disable the 5g service that I pay out the *** for. 

*Sigh*

In your case, if you want a 'real' notification/fix, file a complaint through the BBB.  Since T-Mobile has outsourced almost all of its US based support, you'll be getting standard troubleshooting and generic responses.

Good to see this has been a known issue for over a year and we're still having the same problems.

Full 5G UC and .12Mbps

Bravo T-Mo. Bravo 

so i didn't read all the replies and I have had this issue with both Android and Iphone most recently the Iphone12 pro max(1 year old) and then android is technically last one a S7 plus tab phone was S22plus. Are you all switching off your Wifi buttons when not on your or a known wifi network? Because as my ex the programmer explained that the phones will always try to first  find a wifi signal then use data. So if always "on"but not connected then you are basically throttling your own signal as well as burning through your battery faster. The dead "spots" are the line between moblie data and wifi trying to kick in. Some may already know this, some may not but next time it happens just turn off wifi and wait a few moments to see what happens, possibly reset the phone ot your network by going full airplane mode. But 9/10 this is why for me the other 1/10 is Iphone or Android needs an update. Both systems if its blue in the control panel, its on, whether you are connected or not. To turn off Android completely just press the eifi button, for Iphone go to wifi settings and turn off there, with apple if the button is white, its constantly searching lightly so make sure you completely turn it off.

I have been experiencing this same thing off and on for quite some time. In my case though calls don't always go through. So I will have full 5G bars but the internet goes out. When this happens, I try to call my voicemail and it looks like it connects but I don't hear anything. Then it all works again. I have called tech support a few times. The solution is to reset the network settings and reboot. While that helps, the issue reemerges. It is not a fix. I broke down and called tech support again last night… It certainly illuminated things for me.

The rep I spoke with last, I believe Kiel (outsourced most likely), must have thought that I am stupid. He "fixed" the issue by having me set the phone to 4G/3G/2G (essentially prevent the phone from using 5G). THEN this individual tried to tell me that when I go to an area with good 5G connectivity that my phone would connect - nevermind the fact that he had me turn 5G off. Add that -LIE- to the fact that I AM within 5G signal and I was one p-o'd customer. All in all, T-Mobile support is next to absolutely useless (and infuriating). Also, this issue is CLEARLY a 5G issue. The only reason I went out and bought a new phone that supports 5G was due to T-mobile's "push" for 5G.

I have been a customer for just shy of 16 years. That will end soon.

Tmobile has a lot of dead zones, and unusable 4g lte service in areas that are listed as 5g Ultra Capacity.  Reps will claim that the areas aren't 5g , have capacity issues, are being modernized or undergoing maintenance.  Sometimes for several years (/sarcasm).  These are go to excuses, and yes, their 'engineers ' have even admitted it as I've caught them in their lies.

I tether; have done so for 10 years. I had connected to Tmobile at 26mbs until last year, page loads went from non existent to on a lucky day 7 mbs. Meanwhile i get Netflicks free. Im moving to another carrier.

My family and I have been having this issue since October 2022! T-Mobile worked great for us until then. We live in an area that shows full 5G coverage. I've made multiple calls over the months. I was told we can get refunded for the number of days the service hasn't worked, but only one time. Being that it happens for a few days to weeks at a time, then shapes up, then acts up again, I'm hesitant because I'm up to over 100 days of not being able to use our phones. Live in Central Texas, everyone I know with AT&T and Verizon always has working service. T-Mobile only keeps us right now because I can't afford to pay off 3 of the lines that are getting paid through a monthly credit promotional. Funny how the "uncarrier" with "no contracts" does their discounts and promotions in such a way that it's essentially the same thing as a contract. Was camping this past weekend out near Ft Hood, and sure enough, only the T-Mobile members had no signal. The world's leading carrier isn't doing a great job right now.

i’ll preface this by saying i have a less than year old iphone 13. made an entire account just so i could post my frustrating experience.

TL;DR: this is exactly what i tried. open settings > cellular > cellular data options > voice and data > switch to LTE. then i went back to voice and data > data mode > switch to standard. then restart phone. my phone is finally loading things without wifi, and im not having the “no internet connection” problem anymore. maybe this could help someone so i decided to leave my experience.

the issue at hand has been following me from phone to phone ever since i got my first iphone in like 2014 or 2015. even if i had full bars of service and my 4g or 5g was on, if i was not connected to wifi, nothing would load. social media would not load, my texts would take forever to go through or sometimes not even go through, dropped calls, etc and no one else in my fam ever had this problem except me. ive been so fed up to the point where i took my phone in, and tmobile ppl tell me try resetting network settings when that happens. of course as im standing in front of the tmobile person, in the tmobile store, their suggestion works exactly as they thought it would but as soon as i left the problem came back and i would try the suggestion again and it would not work anymore. i have read on this problem SO many times trying to fix it and i think i finally did something right this time. this is exactly what i tried. open settings > cellular > cellular data options > voice and data > switch to LTE. then i went back to voice and data > data mode > switch to standard. then restart phone. my phone is finally loading things without wifi, and im not having the “no internet connection” and "could not connect/secure network" problem anymore. maybe this could help someone so i decided to leave my experience.

I just want to add that I've had this issue since I purchased my note 20 ultra 5G. I thought the issue was my phone until I finally found the recommendation to disable n71. That seems to have completely fixed the issue but my speeds and signal are less abundant.

I have the model with 512GB of storage and the max ram which was not cheap. I hope someone from T-Mobile actually checks the forums because this issue is so annoying and apparently there are multiple users across the network experiening it on all different 5G phones. On one hand it's nice to know I'm not alone, but on the other it's disappointing that such a huge issue exists and they are not able to resolve or acknowledge it.  This problem started after the sprint merger for me. Previously I had nothing but great service so I wonder if it just has to do with how they integrated the two networks with their new available spectrum.
