Hello guys. I kind of have a problem with a specific LTE band. In short when I switch to that band (7/2600), I lose my signal and it does not recover (It keeps searching for it and not finding it.) It recovers only if i reboot my phone or if I switch it to airplane mode and back, but there is still no 4G. Any information will be useful. Thanks.
Nevermid. It works now (don't know why)

I notice that thís problem just happened today. Sometimes my network signal gets lost, as so for the data.
When I have my network back, instead of showing 4G Lte, it shows H ( OR H, 3G sometimes). I've tried change it to LTE as a preferred choice but it wont let me choose it. It automatically turns back to GMS preferred.
I don't know if there is sonething wrong here. It had worked fine ever since I flashed the Rom. Only today did I encounter such problem.
Anyone knows what goes wrong here?
Thanks so much for helping me out.
Hi, everyone!
So, my Nexus 5 only works when I set it to use 2g network.
Explaining it more clearly: when I set 3g, everything starts to go a little crazy. The phone signal gets lost back working, sometimes it doesn't even recognize the sim card
When I try to access network settings and network operators it gets really slow and sometimes the phone crashes and reinitiates.
I've tried setting a new rom and I am running the most recent version of Cataclysm right now. I've tried changing the phone modem driver too (actually I think I have just reinstalled it) and nothing.
Interesting thing is: sometimes when I turn 4g on, the internet signal works, but when I try to make a call, the signal gets lost and it appears a "turn off airplane mode" pop up.
That's it, guys. Thanks in advance for any help you can give to me and I'm sorry for any english mistakes...not my native tongue.
Hello guys, I've been trying to find a way to force 4g only on my samsung SM-GT920F ( using the lastest version of everything);
I found about *#*#4636#*#*, which doesn't do anything, I found some app that will get me into the testing mode or whatever the name is but the app either crash or give me this imgur.com/aNgCDY2
Don't mind the screenshot, I actually get around 3bars of 4G+ but for it switch to 3g for a few second everytime so I'd like to force it to be 4g, thanks you!
I think the problem would be that every time you call, it switches to 3G/2G for better connection. Unless you have VoLTE (I think), you might not be able to.
Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.

I was hoping to find some answers here to a strange problem that's happening with my Poco X3 NFC.
This hasn't been much of an issue before due to WLAN coverage, but I'm more in need of mobile data right now, and wanted to use LTE instead of 2G or 3G which is quite slow in comparison. My provider does support LTE, I've checked everything on that end.
Whenever I turn on LTE, my phone immediately is stuck, gets a black screen and reboots to the recovery menu. After that I have to set everything to airplane mode quick, disable it, and then disable mobile data very fast to stop the loop. There's absolutely no such problem with 2G or 3G set, but as soon as I use anything LTE related it's stuck.
I've tried a factory reset, I've tried no SD card, I've tried both sim card slots. I've also tried every possible LTE combination set via *#*#4636#*#* and it happens with each and every one.
I've gotten messages and pages to load with LTE in my status bar, so theoretically the connection does work. It's just the bootloop afterwards that makes everything completely unusuable.
My phone is out of the box, nothing custom done or rooted. I thought that maybe a few MIUI updates would fix it because there were loop issues, but nothing helped so far. I'm running MIUI 12.0.8.0 stable right now, Android 10. I do have warranty, but first I'd like to know whether the issue might be fixable on my end.
Thanks in advance!
Same problem here
