Mobile data half working. - Galaxy S 4 Q&A, Help & Troubleshooting

I don't know if this is carrier issue, but I decided to ask here first.
My mobile data is working on certain apps only.
For example, facebook will not be able to receive data but reddit will be able to.
Some game apps will connect using data, but most of them can't.
Chrome seems like it works fine, but gmail won't connect using mobile data.
I did root my phone using Odin.
Any help? thanks.

is it 2g or 3g or above? well if 2g it ll take a bit time n you have to refresh it all the time.

Really need some help on data from people in the know

Hi guys
wondering if someone can help me with an issue im having regarding mobile data useage. I am in the UK and I live in an area where 3g is non existant so I have switched to GSM only in the settings. My problem is my phone is constantly using data and I dont know why or how to stop it.
I downloaded an app to show mobile useage, calls, text, data etc
My provider charges me £4 per 1 Mb (this is 1024kb yeah?)
Well I then went into the settings and edited the providers auto settings to stop it from connecting, and left my wi fi on. When I went to bed, my data was showing 0.24Mb, when I woke up this morning it was showing 1.23Mb (with a cost of over £4)
What is causing this? Far as I can tell I have manually stopped the phone from connecting but something is using data. I have the Gmail sync option enabled (but wi fi was on) but still, it went up 1 Mb whilst I slept.
Can someone help me out with this issue please as its starting to confuse me
As far as I know, push email doesn't work over wifi. So if you have google syncing enabled, it keeps a small mobile connection open at all times over which email notifications are sent.
I'm not an IT guy, so I might be wrong But just try to disable syncing and see what happens!
I opened the thread "strange bug" related to this. In my case it uses more 3g band only if it's attached to the pc via usb. When I must attach the X10 to the pc I disable the apn with apndroid.

gmail does work on wifi as far as I can tell. However, I have now gone further into the internet settings and wiped all of the data and the phone now cannot connect. Now this will save me a bundle of cash, but also means that I cant get my internet connection when away from wifi. The APN apps looked good but a lot say dont work with CDMA networks, which I can only assume im on as the apps do nothing
I use WiFi too. But when X10 is attached to the pc it continues to use 3g band even if in the notification bar the WiFi icon appears.

well I didnt know that.
I can confirm that Gmail sync DOES work over wi-fi as I have completely deleted the phones internet settings now and am still getting my email.
So this means I will no longer be getting charged for data useage, but cant get internet other than wi fi
cybrid3, you didnt need to wipe the apn/internet settings, there is a simple tick box in /wireless controls /mobile networks/ MMS and data <<, unticking this will stop the phone from using any mobile data (sms/texting still works).
Turning off 3g doesnt make any difference as the phone still uses data over gprs or gsm.
These phones are real data hogs and its best to get a cheap plan if you can.
yeah, but if I disabled it all, then I would not longer have MMS and that is something I do use
Ask your provider to:
1. block data
or
2. give you APN settings for MMS only.
Theres also the possibility that wifi is set to disable itself after the phone goes to sleep.
I left my wifi settings on and let the phone sleep. Based on testing through the wifi active time on spare parts, the phone accessed data through the carrier.

ask your provider for wap access not data
its very cheap
this way u can send and get mms
Why don't you get a plan that includes unlimited data? Only cost me £5 a month extra for that on uk vodafone.. Well worth it.

I have unlimited data, but they say I have gone over my fair use policy so something has been in the background. It used 1 MB whilst I slept. The plans with fair use of 1GB seem pretty useless now

Data and Voice at same time on Samsung Vibrant

Has anyone had success in being on the phone using voice, and browsing the internet, using data, at the same time on the Samsung Vibrant, with T-Mobile?
I was able to perform this most of the time with my HTC HD2, with T-Mobile.
I searched, and can't really find an exact answer.
It worked but i was using wifi

Yeah, mine probably works on Wifi, but I am talking about mobile data, such as 3G. My HD2 did this most of the time.
If you are on 3G then yes you can.
This really only works well with a fairly strong 3G signal. Otherwise you may drop to 2G during the call and only be able to access data over wifi.
It works for me some times. Each
time I try I get different results some slow some fast or not at all. I am in the same place so its not my location. Its odd u was tempted to post a similar question.
Sent from my SGH-T959 using XDA App
Yes, I can use google maps, drive my car, and talk on the bluetooth all at the same time. The Vibrant works great. Only when it drops to Edge speeds, then ya lose the google maps, but the call keeps going.
Mine works as well, I've had my laptop tethered several times downloading large files, and answer a call and it keeps downloading no problem. I haven't noticed if if it's just a 2g/3g thing though as it usually stays on 3g for me most of the time.
I have no probelm doing voice and data both wifi and 3g.
wtf is up with ppl and the HD2.....

[Q] Mobile Data on Nexus 4

I purchased a new, unlocked, Nexus 4 several days ago. I had a new SIM card installed by T-Mobile the same day. Since I have a plan with a 2 GB mobile data download, I want to keep an eye on my mobile data use. I set up the entire phone using only WiFi, and the data download info under WiFi shows it. The Mobile data also continues to grow.....not by much...only 5.24 MB over three days. Other than several phone calls I am not aware of any data downloads via the mobile phone. Can anyone help by telling me what gives? Thanks.

Not sure what caused that but even if you go over your 2GBs of data you won't be charged, you will just be reduced to edge speeds.

an app or two working in the background, checking in possibly. maybe even a badly behaving app. you can turn all mobile data off.. main phone settings, data usage, mobile data off(will tell you here what apps are using how much data).
Thanks to all for the help....

My thanks to everyone who helped me.
I found this answer to fit my situation best. Per your advice I found what apps are using the mobile data, and each one to what extent. I also found that I can turn my mobile data off. I had no idea that certain apps periodically use the mobile data in the background. Obviously this is my first smartphone. Thankfully, I have several Nexus 7's to have a least a little experience with this device.

Mobile data used even when disabled in settings

Hi,
I have a Nexus 4 with latest KitKat and franco's kernel. I didn't update via OTA. I keep my mobile data disabled, but it seems that my phone randomly use mobile data. Data graph does not register it, but I can here the noise in my computer speakers, and my stupid mobile provider always sends me SMS when I start using mobile internet, so I know it's using it. So, any idea why this happens and how to stop it? Thanks.

Is it happening when your phone is slipping back into 2G - even if not being used the phone send paging signals to the network every so often - you'll hear it especially before a call or SMS comes in as the network sets up the call. Whilst technically it is transmitting small amounts of paging data it isn't charged to you.

Well, I keep it on 2g only, so that's not what is happening, and I mentioned that I get sms from provider when my mobile data is used. I just upgraded to 4.4.1, so I'll see if it still happens.
In meantime, if anyone has any idea why this might happen, please post.

No mobile data for some apps??

Hi,
Lately I've been having issues with certain apps not having a internet connection while others work perfectly. For example some time snapchat doesn't load messages and same for whatsapp.. After a quick restart they work again (but stop again after a certain amount of time).
Did anyone have the same bug? Is it provider related? do I need a new sim? Do i need a factory reset?
I tried to delete all the app data but that didnt work..
Thnx in advance
I get this sort of behaviour on APC8. Will be using YouTube or some other app, lock the phone, come back to it a while later and internet doesn't work with said app after. But other apps work fine. Have to close the app right down and reload it for it to work again. Doesn't always happen, but when it does it's annoying. Find it happens more on WiFi than 4g. Also not all the time. No root here.
