What's using up my mobile data?

When ever I check my data it seems to go down everytime I check it, even when I'm not using any Internet etc. Just wondering if there are any apps secretly running which are using it up, or is it something else?

You can also check in Data Usage under the graph which applications are using data and how much they are using.

HT201299 After installing an app on iPhone 5s, I can't use it outside of wifi (using cellular or mobile data) and the app is not listed in settings to enable its use of mobile data - any clues on what is wrong here?

After installing an app on iPhone 5s, I can't use it outside of wifi (using cellular or mobile data) and the app is not listed in settings to enable its use of mobile data - any clues on what is wrong here?

Steps to take to resolve this issue:
1/ Turn off Wifi
2/ Ensure Mobile (cellular) data is on
3/ Turn iPhone OFF and then ON (re-boot iPhone)
4/ Without turning Wifi on, open an app that requires mobile (cellular) data.
5/ The app will now show on the Settings list with the option to enable or disable mobile (cellular) data
6/ In time all apps that require or use mobile data will be added to the list automatically.

How can I find out what is using all our home data?

We have a huge amount of data every month but over the past few months we are cracking thru it like crazy. I want to know what is using it all. We have changed passwords to ensure it wasn't outside this house.

Hello,Do you have mobile devices and tablet/s connected to your modem?If so, turn off "Background Data" in Data settings plus any automatic updates etc etc It could be that someone in your home is using it with high data downloads? If ou have multiple PCs, turn off automatic updates in Windows, to advise but not download.In your portable devices, there are a mutitiude of apps that update without your knowledge. Would need more information from you to make specific suggestions Hope this helps you RegardsProfessor PhoneI'm not a Telstra employee. I have been a mobile subscriber since 1963.If my advice has been helpful, a Kudo "tick" would be most appreciated.If my advice has solved your problem, please also mark it as a Solution

What's wrong with my mobile data network?

I've had this 2nd hand iPhone 4 for almost 2 months and everything has been working perfectly until today. I was using viber and sending messages to my friends and it suddenly stopped working and i have no idea why, i thought i just lost my 3G for a while so i waited a few hours for it to come back up, this started around 3pm and it's 12am right now and it's still not working... Everything else worked such as skype, twitter and the internet but for some reason i couldnt send and receive messages on viber and imessage. I also didn't get any notifications from ANYTHING during the whole time until i connected to my wi-fi at home which i then got flooded with messages, tweets and etc.
I think that theres something wrong with my mobile data network and i dont really know what it is since everything was working fine this afternoon and it just suddenly stopped? Connecting to Wi-fi makes everything work fine and i actually receive notifications and am able to send and receive messages to my friends on viber and imessage.
Can anyone help me?
My carrier is CSL and it has unlimited data if anyone n

I havent contacted my carrier and i really dont think they will be able to help since i go to them every month to pay my phone bill and they can barely speak english...
I've turned my phone on and off 3 times and ive also reseted my network settings

How do I find out what is using up all my data at 3 different times of the day?

At exactly the same time, 3 times a day something on my computer is using up all my data allowance. Any suggestions on how to determine what is doing that? I have turned off Windows update to manual.

With Windows, Msconfig in diagnostic startup. If the problem goes away, use selective startup to isolate system services or startup items as the problem group. Once you know which group you can use the tab to enable individual programs in the group then restart to test for the problem. Don’t forget to use Normal Startup in Msconfig to return the system to normal. If you find the problem program, either uninstall it or use the program’s configuration to fix it.

What is use Wifi in Mobile

I have purchased new Mobile E-71 Nokia
I understand function of Bluetooth but what is Wifi for
How can i use it.
If my laptop is having internet connectivity and if i switch on its Wifi,Can i use internet on my Mobile E-71

Yes, you can. But, I'm not sure why you would want to if you are already on the laptop. It has to be running anyway and connected. It varies in different versions of Windows. Basically, you go into the networking and tell your laptop to allow others to use it's internet connection. That's how you share the DSL connection. As to linking the phone and the laptop, perhaps some of our more experienced networking people on here can help. Also note, it may require a Bluetooth connection, but i leave that to the more technically savy.

What's Using All of My Data Storage?!?! Mysterious "Other Data" ???

Has anyone found out the actual solution to this problem?!?! I had 12 of 13 gb used, less than 1 gb free. Why?? I've NEVER downloaded ANY games or side loaded ANY Android apps. After the 10.2 update I deleted all of my nonessential apps, including FB, Twitter, Foursquare, and LinkedIn. That leaves me with password protector, adobe reader, The Weather Channel, and Box (which, by the way, doesn't load anymore so it is pretty much useless). Now I have 8.81 used and 4.37 free. It's been said that the OS takes 2.5 gb. So what is the rest of this stuff and why can't anyone get rid of it without doing a wipe? Seriously, we have to do a wipe? All of my pictures, videos and music are on my SD card and it has 19.7 of 29.7 used. My pics, vids, and music is less than 12 gb. So why is my card full of that stuff, too?? And why am I yelling?!?! I've deleted everything that I can, even important things, cleared my cache and cookies, never downloaded games or Android apps, and never downloaded leaked updates. Why isn't Blackberry giving a solution? Or at least telling what this stuff is. Does anyone have any insight? Thanks in advance.

The sizes of the apps you deleted are not very large - FB 98MB. Twitter 8.4MB, Foursquare 13MB, Linkedin 5.7MB
Look in Storage and Access - Device Storage details - Storage - Pie Chart and list of apps.
Mine is System 2.55GB, Apps 1.68GB, User Files 63 MB, Free 8.89Gb.
I have 5 pages of apps, which includes 8 android apps.
Pictures and videos are all on sd card.

HT1695 After I have connected my iPhone to my laptop I cannot get my mobile data to work the laptop. Does anyone know what I need to do to get it working?

Can anybody help me with this? Can't get my mobile data to work on my laptop while my iPhone is connected to it!

Not clear what you mean by "getting mobile data to work on my laptop." Do you mean using your phone as a mobile hotspot for your laptop? Did you enable Personal Hotspot in the phone settings. Is hotspot/tethering provisioned in your carrier data plan?

My iPad is being used at home on wifi but some how running up 8gb in a month of mobile data charges??? It's a pad 2

As above since getting my iPad replaced I used almost 6gb last month but was using it on 3G for a week. In July only used it on home wifi network but orange say I have used 8gb of mobile data and slapp me with a 250 quid bill. Help! I am not thick i have turned off mobile data but have not used it at home on wifi.

You've somehow already pinpointed the problem, of course (Office). Many people seem to run it successfully. Maybe re-install it?
Anyway, if this were happening to me, I would be looking more closely (via Activity Monitor) at how the RAM is being used. With "All Processes" being shown, sort by "Real Memory" and see who is the hog.

Ellipsis 7 tablet - drops wi-fi and goes to mobile data w/o telling you, and for no reason?

I don't totally hate my Ellipsis 7 tablet. It does have a nice, bright screen, and it does have a fairly fast processor.
This is where the compliments stop.
1.) It's glitchy. As others have stated, icons do seem to disappear.
2.) It seems to "lose communication" with my high-end Sandisk micro-sd card (that has no other problems when used in my smartphone.)
3.) The battery life could be a lot better - you will charge it every day, even with minimal use.
but my biggest problem with this tablet (which I got from my local Verizon store) is it's "sneaky behavior" with mobile data. I am nearly convinced that these devices are designed, intentionally, to use up your mobile data whenever possible, even when solid wi-fi is available.
Have any of you Verizon Ellipsis 7 users, that use these primarily at home with wi-fi available, noticed a rather large increase in the mobile data being used?
This is sort of long, so I appreciate everyone who takes the time to read this...
Here's my scenario; which I can duplicate.
I live in a place with 2 strong wi-fi networks available. The tablet accesses both of them with no problem. Speed tests show 10Mbps download and 0.768 Mbps upload, the speed we pay for.
One night, I get the text messages from Verizon that I'm close to using all my mobile data. (which I appreciate) But I'd been getting so many texts, emails, etc., that day I didn't look to see what the alert was. My bad! So, I'd gone over and approved $10 to upgrade with one more GB of data. I figured it was a fluke; that somehow I had turned off my wi-fi, or it had gone down, or somehow something happened that made the tablet switch over to mobile data.
...but I was watching more closely now...
less than 24 hours later, I'm getting those messages again! I'd used one GB in less than 24 hours??? So I called Verizon, and we went through the normal putting limits on the device, etc., so it couldn't happen again.
So then, I asked him the simple question? When not 1, but 2, strong wi-fi signals are available, why would this device switch over to mobile data, WITHOUT letting you know???
He couldn't answer that. He transferred me to someone else that was "higher" in techincal support. She was a sweet girl, and really wanted to help me, but she never understood my problem. At one point I said to her, "Look, it's simple. These devices always default to wi-fi if available. What would make them disconnect from wi-fi and go to mobile data instead?" Her answer was that she needed to look up if a tablet was supposed to connect to wi-fi first... uh, OK.
At the end of a very frustrating call, she offered to send me a box to ship it back to Verizon in. They would then decide to repair or replace it. I would be without a tablet for a minimum of two weeks. I said Thanks but No Thanks, I would just disable mobile data entirely. The lady I spoke with did not seem pleased with my decision, but what could she do? And we ended the call.
So, I'm still trying to figure out what is making this thing kick over to mobile data (remember I just shut mobile data off entirely before I hung up with Verizon) and I was currently connected to an external bluetooth speaker (which shouldn't have anything to do with anything, I realize), when I started a video on YouTube.
Now, mind you, I was ALREADY showing connected to a strong wi-fi network.
And up comes a dialog popup, asking me to turn the wi-fi back on, even though I would incur additional charges!
BUSTED, VERIZON!
This message doesn't come up when it tries to switch over from wi-fi to mobile data unless you have completely shut off mobile data.
I only mention that I was connected to an external bluetooth speaker because it is the only way (SO FAR) that I have been able to duplicate this "silent switchover" repeatedly.
If I'm on Youtube first, not connected to my bluetooth external speaker, the device will stay on my wi-fi network when I pause the video, connect to the bluetooth speaker, and then restart the video.
If I'm already connected to the external bluetooth speaker, and then open a browser window or youtube video, the device will attempt to change its connection from wi-fi to mobile data. There is no reason for this!
Yes, yes... I realize that being connected to an external bluetooth device should have absolutely nothing to do with whether the tablet should keep its wi-fi connection or switch to mobile data...
except that it does! And there may be other circumstances that I haven't found yet... I don't know, but I'm watching!
At the end of the day, ANY DEVICE THAT IS GOING TO SWITCH FROM A WI-FI NETWORK TO MOBILE DATA, FOR ANY REASON, SHOULD TELL YOU IT'S GOING TO SWITCH, AND LET YOU DECIDE TO ALLOW THAT CHANGE OR NOT, especially when there is NO REASON for the device to switch in the first place. In the same household are my Samsung Galaxy Note 3 and husband's Galaxy S5. They never exhibit this behavior, and yes, we use internet on our phones at home rather frequently.
Watch your mobile data folks...
Oh, and the Verizon lady called back about 30 minutes later... asking me again to agree to send my tablet in. I explained to her that I could now duplicate the problem. I told her that it would be easy enough for them to check and see if all devices are doing it (which I'm guessing they all do! there's not enough memory to download any apps, so I doubt it's that...) I said that with the millions of Ellipsis 7 devices they have, someone in tech support can grab one and try it. Still no luck, and she still wanted me to send it back and be without a tablet for 2 weeks or more. I declined.
Anyway, if you've read this far, I thank you! I would like opinions as to whether you think this should be happening or not, and whether you have had this happen to you or not with this tablet. Thank you for your time!

Hello this is happening to us also (minus the Bluetooth speaker). We can't figure out what is causing the data usage. I turned off mobile data as soon s I activated the device, and got the message that unless I am connected to WiFi.....(that is exactly what I wanted). We watched Netflix for about three hours, then the alerts started. Like you we have many devices connected and never used over 2GB now all of a sudden we have used it in a matter of hours. My husband called Verizon and got the usual doubting Thomas response. I understand that they don't know my device settings. So over the phone we check all the settings and turned off every possible culprit eating up the data and end the call. By now I have purchased another gig for the month! Assured we are NOT using mobile data, we continue on the IE path to bliss. HA! A few hours later I check the mobile data usage on the Verizon website and that darn thing is still using data. After two more phone calls and two VERY uneventful trips to the local store we were told to take out the sim card. This has stopped the data usage, but it defeats the purpose of having the data plan. I could have just stuck with my Surface. Verizon sent us a new sim card. Its been installed and I have set my homepage to Verizon mobile data usage (just kidding) but I am on that site a lot. I am surprised at the number of complaints about this device. When we called the Verizon support acted as though this was the first time they had heard about this. Loved your post, you should write for a living.

Calendar app eating up my mobile data

Since upgrading to an iPhone 5S with iOS7 I've regularly used up my mobile data allowance of 750 MB by the mid of the month. Almost never ran into that problem with my iPhone 3GS and iOS6.
I've checked mobile data usage in the settings and apparently the Calendar app is the culprit. It has racked up 421 MB in ten days. I am using iCloud. How is that even possible? Is anyone else having these kinds of problems with the Calendar app?

Same problem for me too. (iPhone 5 not 5S)

What are the settings in i phone 4s for connecting internet in mobile data ?

what are the settings in i phone 4s for connecting internet in mobile data ?

Did you ever get a reply to this. I have the same problem. I have the same problem when even when I reply to an email... no photo shows up in my new reply message. The only way I have figured out is to use the "forward" option.
But this still does not solve the problem when people email me back... I have no idea what photo they are speaking of. Instead of a photo... there is a <photo name of some sort>.
Let me know if you ever hear on this one.
Many thanks.

I bought an unlocked 3G and when I try to use the internet, it says 'Could not activate mobile data network'.

Hi all,
I have recently acquired an iPhone 3G 16GB. It is unlocked and I have put my sim card in (Virgin Mobile) and used it without problem when calling or sending text messages. The internet all works fine when connected to a wi-fi network.
In the top left hand corner it says '3G', however if I try anything related to the internet (Safari, Twitter etc.) a message will appear reading 'Could not activate mobile data network'. This is very inconvenient for me. All internet related activities work fine when connected to a wi-fi network.
Is this a problem with all unlocked phones? Is there a solution to this? Or am I simply unable to use the internet without wi-fi on this model?
Any help would be greatly appreciated, all questions may sound silly, but this is my first iPhone and I am very inexperienced with them!
Thanks

First, you don't have a 3G if you have iOS 6.1.4. The 3G cannot go higher than iOS 4.2.1. That is not related to your problem, but worth knowing.
Let's try the obvious first. Tap the Settings icon. Then tap General. Then Cellular. Is Cellular Data on? Is there an entry for APN? If there is contact your carrier and ask what the APN settings should be. If there is no entry don't worry; the APN is automatic with your carrier.
