App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?

Have you check you settings-wireless & networks-mobile networks-use only 2g networks?

ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.

1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above

Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.

I have your same problem could you be so kind as to attach the img you put so I try too? thanks

Then you will have his phone.

you mean....?

i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.

i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.

Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.

tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

[NEED HELP] Data Connection Problems with CM7

I have problems activating 3G data when switching from WiFi.
Before rooting, I used to keep my data off most of the time. If I wasn't in a WiFi area I would manually go to settings>Networks>Mobile Networks and turn my data on. It would show a 3G/H on my status bar.
After rooting and flashing CM7.1, I keep my data on all the time through my power widget in the status bar. Even when I'm not in WiFi, the 3G/H symbol does not show in the status bar.
I have tried switching it on manually from the settings>network>mobile network but that hasn't worked.
I've switched to flight mode and back and rebooted my phone and it hasn't worked.
I have an active 3G data plan from Vodafone with all settings in place
Is there something I can do to make my data plan work again?

it happend me before but i dont have root and im on stock rom,
Hold the power button till phone options pop up and click data network mode and wait.. It could take up to 2min for the phone to fine a 3g/h network. If that dont work try to switch it to 2g. Maybe your carrier has low signal where you are...
If those dont work restore to stock rom.
Sent from my GT-S5830 using xda premium

I have a minimum of three bars of signal anywhere in my house.
Ive tried both 2g/3g
I dont have a data network mode option on CM7 when I press the power button
When I had an unrooted stock rom, the power button button would never work for me

I have the same problem with the icsunday rom for galaxy ace. I like the rom its faster but i cant connect to 3g/edge. I have tried a lot of modems and doesnt work. Can someone help me with this?

I had that problem you really should check your apn settings sometimes your default apn is disabled or even gone
dont why it happens but it does sometimes =)

Try flashing a new baseband from SamMobile.com

It's an outdated thread, but it's not the correct section, why don't you try to configure APN manually? or coping the correct APN file and setting the correct permissions?

ohh..okie,sorry for that and thank you for telling me....
and sorry for the long long long late reply..-_-.
have a good day!!...

3g/H packet data problem - N7000

Hi there! would like to seek your help regarding my galaxy note, I encounter packet data on/ff and cannot connect to mobile data (internet) but my sim card is working (can send sms and call). i just put my phone yesterday to flight mode and after that it cannot able to connect to internet. I did factory reset and some wipe of cache.. is there any advice? my phone is rooted already with franco kernel (stock ICS rom only). Please help Sir.

Please do not "FACTORY RESET" , You could potentially brick your phone.
1. Try to see if you have your "DATA" on. With DATA off 3g/h/h+ will not work only wifi would.
2. Worst case scenario, take out your SIMCARD and put it back again.

Hi, Thanks for the reply,
I already did some of the basic steps, It just so happen that the history of this problem was because after I put my phone to "flight mode for about 5 hours" and the the packet data icon "3g/H" were no "DOWN arrow" color orange where as I know is a sign of good connection. but the icon only lit the "UP arrow" please help

May also be a issue with having incorrect APN information (Some carriers do not Automatically push out the right details)
Under settings> Wireless And Networks > Mobile Networks > Access Point Names
Check the listings are correct for your network.

Hi, Actually my phone's packet data was working well before I put it in "flight mode" meaning my APN settings is OK. for reference here are some of my screen shots which I edit to see the ICONS status,,thanks for the help!.

Don't know what still seems like a apn issue. Only because I would expect atleast one reply from the network during the connection discussions.
The fact that the orange arrow never lights up to me indicates that the network never gets the sent packets.
Have you tried anything like the apn on/off alps from the the playstore.
Otherwise I cannot see why having airplane mode on for a while would permanently ruin your data connection

Hi, yup but as you know some apn tweatering app is no longer feasible with ICS,
Yes, I am also not convince about after flight mode / airplane mode activation that causes my phone not to connect to the internet. I guess this is related to root bug, this was my 1st time to enable flight mode under rooted condition so I wonder that this might be the root caused. Can anyone suggest to unroot? Please advice, Thanks and Mabuhay!

Bump
Sorry to be bumping this old thready but was the OP able to ressolve the problem? I have been having exactly the same issue but only intermitantly, if I reset my phone everything is fine for a while and then all of a sudden I loose the orange arrow and will only see green.
I am unable to recieve calls or make them, no internet etc. I am on Tmobile UK now EE, have gone through the standard error checking with tmobile but no luck, first they said it was the network being down and no they say it's my phone but I don't see how it's been fine for ages and all of a sudden I have this problem.
It's totally random, I have decent reception so I have say 3g or h+ with 2 or 3 bars but no orange arrow
Any ideas?

[Q] My mobile data disappears until I reboot

Hi XDA, I bought a Z3 Compact a few days ago, and yesterday this weird bug occured for the first time. The data is simply turned off suddenly when I check my phone, and nothing I do will turn it back on.. Toggling mobile data back and forth, searching for networks and clicking different ones, downloading internet settings again, airplane mode on/off etc. - nothing works except rebooting the phone, and then the data works again until next time it messes up. It did it again last night.
I googled the issue, and it seems some S4 users have had same problem with Android 4.4.2? Link to the issue is found here http://support.t-mobile.com/thread/70532
Apparently they report that you cant make calls either when this bug occurs, even when the phone says it has bars, however I havent tested regular calling. I will next time my device bugs out.
Has anyone experienced something similar and/or is there any way to fix it?

I had the same issue but only when Stamina mode was enabled. After a few hours I would lose mobile data and only a reboot would restore it. I cleared data for Eco Mode Controller, rebooted and the problem hasn't reoccurred since. Not sure if this helps or not.

I don't have it enabled, but I will definitely try clearing data for eco mode controller.
Also, I figured out that I can still make calls even when the data doesn't work. So it is not the same issue that is described in the link.
I think you have the same issue as described in this link? https://talk.sonymobile.com/t5/Xper...sappearing-in-Stamina-mode/m-p/845155#U845155
I have had stamina mode on however, so I will try it anyway.

I believe I had the same issue as you: cell signal dying after a while, but more often when cell reception was likely to be cut off (e.g. poor service areas or stamina mode). I'm also on T-Mobile in the US.
You can try the troubleshooting steps I took in this post, but what ultimately ended up working for me was a nano-SIM swap.
If you try all of the above and still haven't managed to fix it, I would suggest a phone swap.
Edit: typo

But if the sim card was the problem, I wouldnt be able to make calls right? I mean, there must be a connection since I can call.
Also, the phone doesn't give me a notification with "No sim card" or something similar..
But then again, weird errors can happen.. I will order a new sim card if the problem persists and I am unable to find a solution

You might be right. My issue was signal, then no signal. I never got a "no SIM card" message, however.
Best of luck!

I am now getting this issue without using Stamina mode. I am currently sat at work with no data, same thing happened yesterday. It worked fine this morning but at some point it has gone and only a reboot will get it back. I am missing important notifications because of this.
It seems to happen when I move around the building and the signal goes weak. The About -> Status page currently shows:
Signal strength: -79 dBm 17 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Disconnected
This is so frustrating.
---------- Post added at 12:43 PM ---------- Previous post was at 12:36 PM ----------
Just rebooted, data is back and now I see this in About -> Status:
Signal strength: -75 dBm 20 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Connected
Time to seek a refund.

I never got this issue fixed, even after repairing the device using PC Companion so I've sent it back to Clove for a refund. I think Bluetooth may have something to do with it though: I use BT in the car and have a Fitbit connected. I spent a day with BT disabled and the issue did not occur. I then went for a run with BT headphones connected and when I got back I had no mobile data again.
So goodbye Xperia Z3 Compact.

Anyone managed to fix it?
Hi!
I have the same issue. I use BT in my car too, but I think I lose it event without BT sometimes..
Anyone managed to fix it?

Just wanted to pitch in that I have the same problem (Z3 here).
I was going to return the phone but reading that the new lollipop update will arrive next week I think I'll hold out and see if that update won't fix it.
/Edit
See if Paul Wheeler3's post here works for you , I cant paste the link since I have posted 10 times here... but google with his name, and search for Xperia Z3 Losing Data Connection. should be one of the top hits.

COPIED and PASTED for your ENJOYMENT:
I thought I’d share a quick tweak that applies to most of Sony’s Xperia Android phones. If you’re on the Three network and travel around a fair bit you’ll notice that occasionally you’ll lose the data connection and it won’t always come back until you reboot the phone. Very annoying.
This happens because Three still have some 2G roaming agreements in place for areas they don’t have coverage. That doesn’t include data roaming however and a lot of devices (including the iPhone still) have trouble with this.
The way to fix this is to set the ‘Network Mode’ to ‘4G/WCMA’. Annoyingly you can’t set this in the ‘Mobile Network Settings’ section, you’ll need to go into hidden service menu to get to the setting. From the dialler, type this:
*#*#SERVICE#*#*
'Service' is typed as you would on a T9 predictive text keyboard, so thats one key press per letter.
Once your into the service menu, choose ‘Network Mode’ and then within this menu choose ‘LTE_WCDMA’.
You’ll see the radio stack reboot (so you’ll lose your connection while it does this).
No longer shall you experience the annoying ‘data never comes back’ issue.
It goes without saying that changing this setting is at your own risk.

You should manually set your network to WCDMA/GSM first. Then do as suggested above.
The problem is that the mode will automatically fall back to whatever is set in the UI if you even load the Mobile Networks control (by simply selecting the menu item in settings). If you leave it stock, then going into mobile networks will cause it to "fallback" into the failure mode. But if you manually set it to WCDMA/GSM then going in to Mobile Networks will only cause it to fallback into HSPA+, which isn't bad.

I'm getting this exact same issue but on my galaxy s5 only a reboot will resolve it I wonder if it is also in relation to 2G networks. I am on EE and the just recently sold to BT could be that their infrastructure now includes 2G coverage with no data for some places? Soon as I reboot back on 4G. Looked in settings and annoyingly only auto ones are 2G/3G/4G and 2G/3G there is no 3G/4G auto connection type guess I need to find a Samsung secret menu?

I am on a tmobile z3 and it says N/A no matter which mode I put it on in settings and then going to that secret menu. Please help. I'm on stock android 5.0.2 lollipop. Thanks!

still have the same bug with my Z3 compact, Android 6.0.1 and it is very resistent, even secure mode without 3rd party Apps, new SIM Card and new mobile phone (but with restored Sony Backup) helped. Vodafone germany and Sony Customer Care are idealess.
Last try will bei leaving SD card out and a reset with Sony companion without restoring backup

6.0.1 Marshmallow Removes Data Toggle (slow/faiLs to recognize mobile network)

So, I knew updating to Marshmallow 6.0.1 would do this, and, I was purposely holding off until I could find an answer on how to restore the Data Toggle option.
But, AT&T and or Samsung are trying to be like M$, and low and behold, they ninja-updated my phone without my explicit agreement........
SO..... Now I'm stuck with this crap situation of not having a Data Toggle option.
Anyways, Now I noticed the following behavior:
When I have WIFI on, I then turn it off.
Doing this should automatically kick in my mobile provider data service.
Yet, it takes forever to kick in. Up to 10minutes!
There's like not way to force it to be enabled instantly once I disable WIFI.
I reset my network settings and still has the same issue.
It seems for some reason the phone just doesn't want to immediately initiate attempting to connect to my mobile network after I disable WIFI.
Anyone else notice this? and or can provide some pointers to get that data toggle back?

Just an additional note:
Anyways, there isn't any pattern I can find that determines why the phone won't try to initiate the mobile network immediately after WIFI is turned off.
This doesn't ALWAYS happen.
(I do know it never was an issue when I had the Data Toggle option prior to the Marshmallow update)
Well, At this point, I've tried this a few times and it works. If the Mobile Network doesn't kick in:
Go to Settings > Connections > Mobile Networks > Access Point Names (( Then choose your access point (Which is your APN to the mobile carrier) (Yes, it is already selected, but choose it anyways) ))
Once I do that and back out of the settings the mobile network kicks in.
*hands in the air on this*..

Factory reset, install Samsung good lock. Problems solved.
Sucks that the mobile data toggle switch doesnt work, this is the best alternative I've found. Bonus is that stupid warning about turning data off doesn't pop up anymore with the good lock

Why do you have to do the factory reset?

I am unable to find Good Lock on Galaxy store! :\

I pulled down the Good Lock apk from the apk mirror site, but, the data toggle STILL didn't work.
At least half the time, I have to to this in order to get the Mobile Data reconnected..:
Go to Settings > Connections > Mobile Networks > Access Point Names (( Then choose your access point (Which is your APN to the mobile carrier) (Yes, it is already selected, but choose it anyways) ))
This is extremely annoying. Can anyone else verify?

OK...... Figured this out.
Firstly, I had Multiple APN set up on the phone. I don't know why, but they ended up being there.
However, I only had selected the proper APN out of all of those for the Mobile Data.
The phone at this point didn't care if it was selected, and when switching off my WIFI, the Mobile Data wouldn't come on, and I had to do the following:
Go to Settings > Connections > Mobile Networks > Access Point Names > Choose THE ALREADY CHOSE proper APN and exit out of settings
After this, the Mobile Data would come on...
SO WHAT I DID:
I removed all APNs that were defined in the 'Access Point Names' section, keeping only ONE APN (The proper one).
After this, the phone would switch on Mobile Data automatically.
SO.... In Conclusion, it looks like this build won't switch to the Mobile Data of a selected APN if multiple APNs are defined in the 'Access Point Names' section...

I've found thru the years that when upgrading to major OS changes, factory resetting helps prevent a plethora of issues. I've rarely ever had any issues with updates across all OS systems (Windows, MacOSX, BlackBerry, Android) because I factory reset. I wouldn't be able to tell you how many posts I've seen across all OSs where a factory reset fixed the problems. To prevent the hassle and headache, I just factory reset. Backing up my messages/phone logs is really the only thing I have to do; all my pictures are automatically backed up to Google Photos and my WD MyCloud, everything else syncs/connects/updates in the cloud (GDrive, GNotes, GMail, etc...) so as soon as I login I'm back to 95%. Downloaded SMS Backup and Restore (Play Store) and my messages/phone logs were restored in a couple min. Setup the APN for mobile data and I'm back to 100%. From there it's just setting up Nova, changing the factory theme, and reorganizing my icons into folders.
