Mobile data connection cant remain alive please help! - Galaxy Note II Q&A, Help & Troubleshooting

I cant seem to be able to keep my mobile data connection alive.
I get 3g/h+ momentarily but after leaving the phone (locking it and putting it beside me) for a few hours I just dont have mobile data capabilities (the 3g/h+ icon is still present in statusbar though).
Have to keep cycling mobile data on/off/on just so it can re-register on the network
Please any help at all is appreciated!

Btw I have the n7100 running on Telcel (mexican carrier)
with the latest Alliance ROM. I just installed it and have done no mods like removing system apps or stuff like that.
APN is set right (checked my cellphone carrier's website for their official settings)
A friend of mine has the exact same setup yet whenever he wakes his phone from sleep his 3G is flawless.....
Any advice?

Check network mode. Set it to wcdma only.

[Q] 2.4 update broke 3g

I flashed 2.3.4 onto my 2.3.3 R800i and now I can no longer get 3g to work for anything other than messaging and phone calls. I've tried everything i could think of in the settings, any clue how I could fix this?
Did you put your apn settings in?

I had a problem with 3G long time ago after being abroad and using Airplane mode and/or data settings. Could not reactivate 3G for some reason and rebooting did not help but I had some on/off widget thing installed at the time and tried one of the 3G or data switches on it and it started working. Hope it helps

I spoke to a rogers agent to get the apn, thanks, wouldn't of know to do it otherwise
Right on man glad you got it worked out I went thru the same stuff when I first got my x10 it was a little frustrating but lesson learned

mine has a glitch where it switches the network it's assigned to by itself. Rogers shows up as two networks, one edge and one 3g/hspa, and I noticed if my reception is bad at a certain location it will sometimes switch to edge only, and not turn back. It's only been doing this after the update to 2.3.4
Edit/update: I figured out you can force the phone to never use edge, if you change it from wcdma preferred/gsm to only wcdma

Data

Hello,
I was just wondering if anyone could explain why ny device has signal, but it unable to actually connect to the internet via mobile data - can't find a setting to turn it on but I obviously kind of need it - using WiFi atm
Thanks

Which network are you using?
Go to Settings --> Mobile network -->Access point names to see if your network is listed and selected.
If it is not there, you need to get APN settings from your provider and manually enter it.

So mobile network is definitely turned on (swipe down -> settings -> mobile network = on)? Do you have G/3G/H symbol next to signal bars?
Also, is wifi off? I found that sometimes when wifi was on and could detect a network but wasn't connected, it could interfere with mobile network.

Might as well phone Orange to see if they can solve the problem. The only option is to do a factory reset in HBOOT.

Just called Orange Internet
Set up another one by following the Orange instructions and that didn't work either.
Could it be that the sim hasn't activated yet? I assumed it has since it says I am connected to Orange and I have signal bars for Orange - although I can't send texts? But I can phone 150..
Just called Orange. Sim card isn't actually active yet - I assumed it was as it appears to show signal.

Serious internet issues..

Hey everyone, I've really annoying Internet connectivity issues on my onex, half of the time it's connected to the mobile network showing the "H" sign on top and the rest of the time it's showing the "3G" icon.
Now my issue is that while it's on the 3g the internet just stops - while playing it disconnects, on the browser it just loading forever, and on programs it get stuck.. while on the H everything is going fine!
I am living in Israel and worked with partner and now changed to "Pelephone" which should have the fastest/best mobile network, and it made no change. I also tried according to.an advice i got here to change my phone on settings to "wcdma only" and still no change.
Please, if anyone has any.idea about this problem and a solution i would be greatful.

By the way i am on stock rom, rooted.

Fixed service dropping and locked LTE

I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

Re: Fixed service droping and locked LTE
To check if it worked. Go into test mode and it should say Lte in network type.

So does this mean we get no 3g?
Sent from my Mind using Telekinesis!
Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

O wow lucky u I can't unselect on Att lol
Sent from my Mind using Telekinesis!
Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

Ok sounds promising but unable to get my ATT phone running ROM cyanogenmod10.1 03/04 nightly into Test Mode using the keypad code provided. This does work for stock ROM phones. Do you know any other way to get into the test mode?
Haven't tried stock. Im on cm10..

Yeah I'm pretty sure everyone is using cm10 or aokp. Not sure if stock is having these problems. If they were I'd be on the phone yelling at Telus.
Xda I747
So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Yes for me and others didn't even get 4g, also it would completely go out of service. Now I get steady 4g.
Xda I747
Any alternative way to get into "test mode" other than using the keypad?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Sorry man, I tried looking around for a way. Could be the rom you're on. I know Liquid and Carbon are fine. Probably a couple more that I don't even know of, others have success with.

No APN reset don't work. Get Disconnect from Mobile Data Service. But I see that the settings says when it is connected Network Type EDGE. But if it gets Disconnected then it says GSM
Edit: Attached ScreenShots
Go to developer options and turn on "cellular data always active". I use that on my phone and it picks up the cell signal almost instantly when out of WiFi range. I am still getting about 5 hrs SOT. ,
Okay i think this is gonna work, instand Switch to Mobile Data. And what to you mean with SOT @calbrs
Today i downloadet the system Update 3.2.2 and I think this bug is patched with this update . Actually no issues with the Mobile Data connection
EDIT: NO DONT work same issue

I have exactly the same issue with my OP3 OOS 3.2.2, no root. It is really annoying
Me too, it isn't handling the switch between mobile data and Wi-Fi very well, not sure whether it's just one way, when i get to work and connect to work Wi-Fi I've ended up having to turn off mobile data to get it to use the Wi-Fi connection.

It is two way. That's my observation. I am very disappointed from the phone which has such problems with basic thing like wi-fi connection. I think this will be my first and last OP phone!
So has anyone found a solution to this issue? What kind of flagship killer has problems with such basic functionality?
I've read on other forums that some devices have a feature called Smart Network Switch, but I can't find that anywhere.
And I really don't think it's the APN...I've modified it in all possible ways and it's still happening...not switching automatically but starts working after switching to airplane mode and back. And the "aggressive" switch option doesn't work either.
If anyone has any idea about how to fix this or how it can be further investigated, please share, it's becoming really annoying. Thanks!

I activated the Mobile Data on in the Developer Options and for me it works pretty well.
The IPv4/IPv6 solution seemed to work. I still have issues when connecting to the wireless network (company wifi, with login credentials and the whole deal) but I used to have the same issue with my Nexus 5, meaning that I have to be disconnected from the mobile data to access the wifi network's login page (forgot to mention this in my previous post). Anyway, I'm happy that I don't have to switch to airplane mode anymore Thanks everyone!
