I have a LTE-enabled SIM on a C6843. My typical scenario is: phone is on airplane mode during the night, and goes out of airplane mode in the morning. Mobile data is always disabled.
Recently I noticed that my operator has been charging my pre-paid plan with data connection charges although I have data connection always disabled. I get daily charges for data connection with 0,000 MB transfered (TIM Brazil, if that matters).
The phone is on CM12.1 20150917, but this has been happening for at least 30 days (based on the data charges).
Has anyone seen similar behavior? Is there some workaround?

Changing data mobile connection from LTE to 3G seems to mostly avoid this issue for me. It does add the extra step to change connection to LTE when I do have to use the mobile network.

Hi, I was wondering if there's an app/service that turns wifi on automatically when my mobile network is not giving me a strong data connection (at least 3g). and of course turn it back off when mobile network is available again.
I want to do this because I have an unlimited data plan, and this will save battery and give me a more secure (private) connection.
Anyone knows of such app/service?
Thanks
My Amaze is having some serious Mobile data (4g/2g) connectivity issues. The problem is this:
1. When turning the screen on, the notification bar shows no mobile data connection, regardless of how many bars I have. Mobile data connection is always enabled under quick settings, but for some reason the phone still can't establish a connection for quite some time, or until toggling mobile data on/off a few times.
2. After finally getting a connection, the phone has further problems connecting. Even though 4g/3g/2g icon is present on notification bar and mobile data is enabled in quick settings, using browser will return only "page not found" errors, and apps will not function properly due to them not having a network connection (foursquare and spotify most especially). Looking at the 4g icon on the notification bar, I can see the "up" arrow flashing as if the phone is sending data, but the "down arrow" is dead as a doornail, not lighting up or receiving anything back. This happens regardless of how many bars I have.
3. On the rare occasion that the phone's mobile data connection does work, it's super slow and acts more like 2g than 4g. Simple web pages take anywhere from around 30 seconds to a minute to load, and spotify cannot stream a song without having to buffer constantly.
Does anyone know how to fix this issue? Or had experience with it? Just in case your wondering, I haven't gone over my 5gb data plan yet (see attached image).
Issue resolved.
Apparently this problem is a combination of 2 glitches:
1. When upgrading to a new phone, despite how much data you used in your plan during the billing cycle, on the T-Mobile My Account website, the widget which shows how much data you've used will only reflect the data you've used on the currently activated device. Before I upgraded to the Amaze, I had exceeded my 5gb limit on my Nexus One and was being throttled by T-mobile to lower speeds. My next billing cycle doesn't start until Dec 27th, so despite the fact that I've only used about 70mb on my new Amaze, the 6 gb I already used on my Nexus One still counts for this month's billing cycle even though the T-Mobile website doesn't reflect it.
2. When throttling, the Amaze, which by default is set to WCDMA/GSM auto, is supposed to automatically switch itself off of 4g and only allow 3g/2g connections. It doesn't. For some reason, it stays with the 4g connection even though the connection is, at best, intermittent. This is the cause of the "page not found" errors and app network errors I was having.
So, for anyone else who is wondering how to remedy this, the fix is simple. Go into Settings>Wireless & Networks>Mobile Networks>Network Mode, then tap "GSM only". This will cut off the problematic 4g connection while still allowing for 3g/2g connections. While noticeably slower (especially where I live, since the Florida panhandle only has 2g and 4g, no 3g), the mobile data connection is solid. Have yet to have any connection errors or experience any intermittency. Still, can't wait until the 27th when I can test out the full power of the 4g connection.
I don't believe I was having this problem at first, but now when I leave a wi-fi connection at home or at work, and I try to use the data connection it doesn't work. The phone is not switching to the cell towers for some reason. I have to disable data, and sometimes wi-fi, and then re-enable data on the phone to get a connection. Or reboot
This is stock btw. Anyone else have this problem? AT&T support was no help
Edit> Just left my work network to test it out and it switched this time, so it doesn't happen every time. Which makes it more frustrating.
Mine was working just fine a couple hours ago, now I get absolutely no data. This is very frustrating.
I'm having this issue almost all the time.
After some minutes on a call (after 5 or more minutes) the phone looses data connection (either HSPDA or 3G or GSM).
As soon as I hung up the data connection restores again.
It doesn't matter if using Bluetooth or speaker.
Mostly it happens while I am driving and I have GPS turned on as well...
It did this since day 1. Have tested ALL modems so far and all ROMs (custom or stock). Nothing would fix it.
It's not that it switched from 3G to 2G, it is just loosing any kind of data connection/connectivity.
Is this an operator issue? Vodafone Romania
Any idea?
Thanks.
Hi
The same "problem" here Every time I have a call, the data connection is lost. As soon as I hang up, the data connectin restores again.
I had this issue also with other phones. Maybe it is a operator issue. To safe bandwide??
It doesn't matter if I have 2G/3G/GPS/WiFi on.
If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
