3G stops working?

Hi,
Does anyone have this problem?
Sometimes 3G is working fine, then for some reason it stops working even if the 3G is still switched on from the settings, but the 3G in the notification bar disappears...
I try to switch it off and switch it back on again... but doesn't seem to work.
I tried even restarting the phone but it doesn't work as well...
Anyone got this problem?
Thanks

Yes I am getting the same thing! It's very annoying, my 3G/HSDPA etc was all working fine and now I have noticed it's not on at all. My setting is also set to ON. When I open up the internet it tells me this setting is turned off when it isn't.
When you say you tried restarting, do you mean you did a factory reset? I was thinking of trying that...

It would help if you said what country and network you're on. I had big issues with this on T-Mobile on the UK and I found out eventually it was the APN settings. Lots of people are posting almost correct information but getting the user and password wrong.
From the T-Mobile website it states
User: user
Password: tm

All I'd suggest is finding the APN settings on their website and making sure they're correct. If they are then maybe contact Vodafone and see what they say.

fixed
OK I've fixed it by resetting the APN settings to default.
When I went to the APN settings, the names of the connections had changed, they had a "_off" at the end. The only thing I think may have done this is when the phone goes into 'low power mode' it switches all data off. If I'm right then this is a bug as the phone doesn't change the names back again. Of course it could be something else.

[Q] Help, packet data not working

Hi, the packet data is not working. In settings it's enabled, but the icon next to the battery one is not shown. I tried turning it off and on, but of course, nothing happened. I'm a newbie, so any help will be appreciated.
Before it stopped working, i was testing some widgets ("power toggles", and the one of the aplication "optimize tool box"), and I updated the lighting launcher. I'm not sure that's relevant, but well...
ps: i have stock rom, stock kernel and it's root.

I get the same problem sometimes. Try restarting the phone with the packet data turned on. When the phone restarts, it refreshes the network received and that sometimes solves the problems, i.e. the icon is shown in the status bar. If you still don't get it, that means that the data network is not available by your service provider at that time.

Hi, thanks for the answers. Unfortunately it didn't work turning the flight mode on and off, or restarting the phone with the packet data turned on.
I tried the SIM in another phone and the packet data works, so it's the cellphone and not a network provider issue.

When you insert a new sim to the phone
Or format your phone
U should get two sittings massages
One for mms and one for 3g

make sure you have a working APN
if not, try to insert a new sim (same network provider) and see if it updates APN settings.

Try flashing a fresh stock rom of your region.This might help you.
Rom:JellyBlast V3
Kernel:Kurotstogi
Theme:Xperia theme with some personal modification.

Check your APN settings if it's correctly set. Most problems occur with this.

[Q] No 3g since latest update

Hey,
I updated my phone about 5 days ago to the latest 4.3 and since then I've lost my 3g connection. It has been there a bit but today it's completely gone and hasn't come back.
Tried turning it on/off, switching to airplane, changing from WDCMA to GSM and running in dafe mode. Nothing works.
Does anyone know what the issue is and how to solve it?
I should point out I'm not very tech savvy and don't know all the lingo so go easy on me
Thanks!

Post a screenshot of Settings > About Phone and scroll to the bottom. Is your phone stock or rooted?

Check your APN under mobile networks. Make sure you have an APN .

[Q] Data connection problem .

I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .

After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.

my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here

Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?

I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.

I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe

issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...

Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.

Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!

potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.

No data.

Help. I bought my note 3 the day it came out. I have been running Alliance build 1 since it came out. A couple of days ago I noticed my phone wouldn't connect to data unless I was on WiFi. The 4g icon stays grayed out. I could still send text messages though. But if I opened the my Verizon app, the 4G icon would brighten and it would connect to Verizon. But no other app can access data, even when the 4G icon was highlighted. So I hoped upgrading to build 2 would solve the problem. BUT NO LUCK. Now I can't send text messages or connect to data. Any body have a clue?

update
So I spent an hour on the phone with Verizon. They said they couldn't find any problems on their end, and we troubleshot my phone and nothing helped. So it is something going on with my phone for sure and not the network. Should I try another Sim card? Should I Odin another modem? Should I Odin back to stock and see if I can connect then to data?

Update
Well, I've tried several different modems. None of them worked. What I don't understand is why the modem will connect when I open the My Verizon app, but nothing else. Leads me to believe there is something software wise that won't let it connect. But it stopped working when I was on Alliance build 1 and that problem carried to build 2. HELP

Odin back to stock and see if still persists. If it does then it's hardware. If not then starting fresh and rooting/flashing the rom should fix.

So I Odined back to MJE. Still doesn't work. Odined back NC4 and the modem still won't connect. But the modem/data works. The My Verizon app will turn the data on and connect like normal. There has to be something keeping other programs from accessing the modem/data. Otherwise My Verizon wouldn't connect. Please can anybody help.....

Update...HELP....SOS
So it isn't hardware related. I just turned my Hotspot on. Guess what, the Hotspot works. My wife was able to connect to my Hotspot and use my data. BUT I still can't use it on my phone. Even when she was connected to my Hotspot using my data, I couldn't use data. How weird is that!? Please, help....

Did you actually Odin back to stock firmware or did you just Odin the radio?

I Odined just the MJE modem at first, didn't help. Then I Odined back to stock Nc4 firmware, did factory reset, didn't work. I've spent hours pouring through every menu I could find to see if there was something not turned on, then I did it again. I haven't gone into service mode yet. I've toggled data/airplane mode/global-ltecdma/anything else I could find hoping it would help. Still no dice. But the Verizon app still connects add well as my Hotspot so other devices can use my data.

Did you try your APN settings? With all that flashing you have done maybe lost your APN settings.

To add to the confusion, data decided to start working again today. Looked down and noticed it was back on.
