This phone is automatically turning on the mobile connection after every few minutes

HI guys, so i have this G4-H811 that is running the official t-mobile Android 6.0 2016-06-01 build. The problem is that after every few minutes the phone automatically turns on the data. Im being charged again and again for this. In 5.0 this was caused by an app called come.tmobile.pr.adapt. After updating to 6.0 this app no longer exists but still the problem persists. I have manually checked all apps in the App section in settings all of them say No Data Used under Data. As far as i can tell all apps are using Wifi. I have unchecked Switch to mobile data under Advanced Wifi Settings. But still after every few minutes my carrier tells me that the device connects to the LTE service. This is burning through my plan so any of u have any suggestions?

Samsung Galaxy A6+ Internet issue

I've had my A6+ for about 2 month now and I'm very happy with the phone. But there is one issue that happens from time to time. The phone does not do anything internet related. It doesn't matter if it's my home WiFi or my mobile data. The phone itself shows that it's connect to the wifi but nothing works. YouTube doesn't load, neither does the play store and WhatsApp messages don't get sent. What's weird is that for example YouTube and the play store don't say that I don't have a connection, as they normally would if there is no access to the internet. They just keep loading without showing an error message of some sorts. I've tried to restart the phone a couple of times, even wiping the cache of the phone itself and of the apps. I don't know what's causing it and how to solve it. The first time it just started working again after many hours, but I don't know if it's because I did something or because it was random.
I'm thankful for every idea and answer
I've gone through this before and for me it had something to do with the Data Saver option.
When I restarted while Data Saver was on, this would happen (no internet access even when connected to WiFi or mobile data) but when I restart with the Data Saver off it would function normally. You can still use the Data Saver but just don't restart with the Data Saver on

Click to expand...
Click to collapse
That could be it, although I can't test it anymore. The solution that worked for me and that was given by the Samsung support was to reset the network settings and then reboot. It worked again after that

Question S21 Ultra (SM-G998B) mobile data stop work after sharing data via hotspot

Hi, I have an S21 Ultra 5G, (SM-G998B)and I have problem about 1 month ago. When I am connected to a wifi network, icons 4g is turn on and mobile data stop work. Only way to turn on mobile data is restart phone. What is the problem? I try everething and hard reset but problem not solved. This happens almost every day once or twice
Not sure I understand....the phone will NOT use mobile data when on Wi-Fi. You can force it by going in developer mode and boost speed by using both, that is not the default though. ("Mobile data always active")
"Mobile data always active" is turn off but 4g icons is active in same time as wifi network. After that I turn off wifi and mobile data not work but 4g icons still turn on.
I found out what the problem. Every time after sharing the mobile network via hotspot, when I go to Sim manager and turn off Sim 2, both icons appear and the mobile internet stops working.
1. Turn on sharing mobile data (from sim 1) via hotspot. (sim1 and sim 2 active)
2. Turn off sharing data via hotspot
3. Connect to any wifi (after connect to wifi, only wifi icons appear)
4. Go to sim manager and turn off sim2.
5. After that, both icons (wifi and mobile data) appear and mobile internet stops working.
Does this happen to others?
