Random drop of mobile connection - OnePlus 3 Questions & Answers

Hello OP3 Members,
I have a problem with my op3 running Oxygen 3.2.8 + xposed.
Sometimes my connection drops from LTE to HSDPA and i cant get any data until i switch to plane mode and back. After some searching i flashed the modem zip from this thread, the problem isnt solved. I´ve checked apn settings and
even went with hsdpa for a day but still not better. Any ideas?

No phone signal yet can use mobile internet

I've got a strange problem that I cannot solve or find anyone else that has had the same problem.
I recently updated to Minco V4 and since my status bar has been showing no signal and mobile standby shows 100% without signal yet I have mobile data. I cannot make any phone calls but can browse the internet. No amount of rebooting, airplane mode on/off will work. I've also gone back to both stock ICS and JB where the problem still exists.
My network is T-Mobile and it won't let me manually connect to it but the phone will occasionally register when I select automatic although it doesn't correct the fault. Anyone have any ideas what has gone wrong with my phone?
UPDATE: It seems I can only get a phone signal when select 2g T-mobile network only or connecting to T-Mobile orange. If I untick 2g networks and it connects to t-mobile 3g I can't receive or make calls.
Does your Radio and baseband match?
I installed the linked radio from the MiNCO thread after flashing the rom and discovering this issue yet it made no difference.
I got a phone signal momentarily about 15 mins ago which allowed me to make a short phone call to test it. I then accepted the JB system update from Google and now have no phone signal, just data.

3G disconnect, only use 2G (GSM). Help me!

I installed room ( {Rom}{ICS} Official Global CM9), after 2 days my phone's network is disconnected. I reinstall the original room 2.3.4 but only use 2G when I used dataroaming; completely unusable 3G & network global mode always (I fullwipe data before reinstalling room 2.3.4 ; radio 1.09.01.0312 & APN properly installed). Please help me how to be able to use 3G
because my phone is example:
Unfortunately, I'm having the same problems with this ROM on HSDPA that I was having on aeroevan's ROM. GSM is found immediately on boot, however, HSDPA is very flakey. It will succeed in connecting every now and again, but then randomly drops the signal and won't reconnect. I thought maybe I just had a weak 3G signal where I was testing, but I have a BB Bold for work as well and that can easily maintain a 3G connection on the same network. I also had no problem way back in the day with CM7.2, but that ship has sailed .
Also, when the phone is in WCDMA preferred mode, after a while the phone will lose all connections (usually after a reboot but not always), including to GSM and when I go to reselect my network operator I get the message "Error while searching for networks". No matter how many times I reboot the phone or switch to "GSM Only" or "GSM/WCDMA auto" it never lets me again select my network provider.
Dude you already posted the same thing in q&a why did you post here

[Q] No network data connection

Hello all,
I got my P6 for a few days and from time to time I had troubles to connect the data network (2G and 3G).
When I switch the data on, it connects to the network for 1/2 seconde and then it disconnects (the H+ symbol stays on though). Switching the data off and on again only repeats the problem.
Restarting the phone allowed me to finally have a stable connection so far but since this morning it doesn't work anymore. Removing the sim didn't help.
I'm on B125.
Anyone encountered this problem and managed to solve it?
Thanks!
I may have solved the problem.
Use tweakker from the play store to get the exact apn details for your carrier (mine is Base Belgium) and put them in the apn settings.
Since that I can connect the data without any issue (except a new bug: switching to "2g only" make the connection bug again, except if the data is switch off before and switch back on after a dozen of seconds). It seems that it is more like a carrier problem but that creates bugs only with Huawei products (source: internet).
It seems that the P6 is a very capricious phone, I love it but I wouldn't recommend it to anyone which is not an engineer!

[Q] Nexus 7 (2013) - Mobile data issue

I've been using my Nexus 7 2013 LTE for almost a year now. But since last week I've been having trouble connecting to the internet via mobile network. I have full signal, but no data connection.
At first the issue was intermittent, but now it's constant. Incidentally, sometime after I started getting problems (but during a brief period of time when I did in fact had a data connection) the device got upgraded to Android 4.4.4. Maybe the upgrade had something to do with the issue, but i'm sure that it started happening before the upgrade.
For some time I was sure that the issue was with the network. After long useless conversations with them I finally tried the sim on another device, and to my disappointment, it worked fine.
I also found out that if i change the preferred network mode to 2G, then i do get a data connection. That's not very useful.
Any thoughts?
I've been having a similar problem since the 4.4.4 update. I work in an LTE coverage area, and live in a 2G area. It transitions just fine from 2G into 3G and LTE, but then when I go back into the 2G area it drops signal entirely. Toggling airplane mode won't make it recover, but a full reboot will. After the reboot it works fine again. I'm considering trying a factory reset to see if that helps.

CM11 and ATT network issues.

I have been using Beanstalk 4.4.4 for E980 for quite a while and my phone has been hehaving well. But lately I can't make or receive any phone calls if my network is on LTE. I know that voice is on 3G (HSPA) but when I am on LTE and I make a phone call, the signal switches to H and then it disconnects after I hear one ring. Also, when I receive a call and I am on LTE, once I hit answer, the call disconnects. I then did factory reset and also flashed other CM11 based roms such as Vanir and Blissstalk and the issue persists. I searched on the web and it seems to be an issue with CM11 users with ATT such as Nexus 5 and one plus one users. The rumor is that ATT is experimenting VoLTE in the northeast area (I live in NYC) and that there is a problem in CM11 in that situation. My wife's S4 doesn't have this problem with touchwiz version of kitkat. I can fix this problem by choosing 3G as my preferred network but then I lose LTE speed in data.
So are there any other people experiencing the same problem? Is there a CM fix that I could flash to avoid this problem?
try this
You try changing preferred network to 3G from LTE, and maybe that should fix the issue.
I'm using e980 with CM11 snapshot m11, and starts about a month ago, my phone starting to loose the connection to the mobile network regularly. It happens when ever I reboot the phone, and I have to reboot the phone 2-3 times before it's able to connect again. I switch to the cm11 nightly 3 days ago, as of right now I have been able to connect to the mobile network each time I reboot my device. I saw a few complaints regarding this issue on the cyanogenmod forum. Just thought I share the problem.
