IPHONE USERS WI-FI CELLULAR DATA CONFUSION SOLVED

I am a current Iphone 4s (ios7 updated) holder and over the past several months I kept receiving a message stating I was coming close to using up all of my data for the month. I was on a family plan and this was a issue with other family members as well. This didn't make sense to me because I would normally be using a wi-fi connection network, which I assumed would take any ( web searching, emails, apps, Facetime etc.) and run its course through the wireless network and NOT my data plan. I was wrong. If you are receiving the same notifications PAY CLOSE ATTENTION. Your iphone will continue to use cellular data as long as it is switched on! Even though you are connected to wi-fi it's still using cellular data. In order to STOP your phone from doing this go to settings than toggle the cellular icon to OFF. You can customize in this setting menu as well, which apps you want your phone to use cellular data when not joined to a wi-fi network.This does not influence calls and/or text message usage for people with UNLIMITED in these categories. In fact even if you do not have unlimited it should not effect this either. Remember that if you are NOT connected to wi-fi and your cellular data is toggled OFF you will NOT be able to use the phones applications. But if you are connected to wi-fi toggle your cellular data off and your phone will no longer be charging you for data usage. Wi-Fi is more efficient, I believe than using cellular data, the phones applications work faster. Hope this helps

I have this same exact problem since updating to iOS 8.1.1 on my iPhone 6. Prior to 8.1.1, it was not an issue. My phone is with Verizon.
When the problem occurs, I can't use e-mail, Facebook, Twitter, or Safari. Every app which I try to use presents me with a spinning round starburst thing next to my Wifi or where it shows "LTE".
I've tried turning off Wifi (although other devices such as an iPad can work on my Wifi when the problem occurs), so I know that the problem is not with my local Wifi. When I turn off the Wifi, LTE is shown and my reception is pretty good (about 3 dots showing for reception) and I still can't do anything that uses the internet with any of the apps, which kind of defeats the purpose of having a smartphone.
I've also tried putting the phone in airplane mode and also verified that mobile data is turned on.
The only fix I've found is the one which you already found, which is powering off the phone, then powering it back on, then things work normally on both the mobile data network and Wifi.
The one thing I haven't tried is making a call when it's in this state...guessing that works, but I'll have to wait another 1-3 days for the problem to occur again. Prior with the 8.1 iOS update, I never had to shut the phone off and didn't have this issue occur, so I would guess that it's some sort of bug introduced with 8.1.1.
If anyone else has any suggestions on how to remedy this problem, please let us know!

You don't know how to call your phone carrier? Pick up the phone and call them or go to the carrier store.

5C users Watch your cellular data usage!!

This needs to be brought up just a friendly heads-up in the 5c forum, as there are already long-running threads on this topic in the iPhone 5 forum.
I have owned a 5c for a week now, and have it activated along side my wifes 4s under our 2G shared data plan. So far in that time 5c has used 3~4x the amount of cellular data, despite my wife using her 4s FAR more frequently (for apps) than I do on my 5c.
I have managed to throttle my data usage with now a better understanding of the following:
-Apps will use cellular data, even while connected to a wifi network. So merging onto a wifi DOES NOT AUTOMATICALLY PRIORITIZE it over the Verizon cellular data network.
-Closing out the app when finished does not stop it from using cellular data. Many apps will still siphon cellular data, even though they are closed.... WITHOUT THE USER KNOWING IT. Pay close attention to, and turn off cellular usage for those apps that don't need it. Note you may have to manually re-activate cellular usage for the app when you use it outside wifi coverage. This is a royal pain in the you know what.
-Deactivate notification center... or deactivate those parts of it you don't really need. Personally I don't need any of it so I have it completely turned off.
-Turn off the "Background app Refresh" function.
-Turn off "Location Services"
-In the "Mail, Contacts, Calendars" section turn off the Push function under "Fetch new data". I have mine set to manual.
-Turn off LTE function. The LTE part of the network is not even available to me where I live. I found my phone was RAMPANTLY gobbling up cell data 24/7 and all hours of the night. That data siphon stopped immediately when I turned off LTE. Yes you are in essence using a slower cell network, but for me that doesn't matter since I am under a wifi network 99% of the time. If I ever do need a fast cellular network I will have to manually turn on LTE.
As a final note, this is a SIGNIFICANT difference between the 4s and 5/5c/5s... and should be taken as a warning to anyone wanting to upgrade from the 4s to any of the "5" models. My wifes 4s (on the latest iOS) does not require any of the actions above. Even with REGULAR use of her DOZENS of apps, her monthly data usage on the 4s has never exceeded ~1G over the past 2 years. She never even turns them off, they are always open and minimized on her screen-top.
So in summary, turning off LTE has made a significant difference in my data usage (shown in kb), as shown below.

I am not sure about that, and even then I don't know if I would 100% blindly trust that. Verizon will send you txrt messages when you approach your data ceiling for each billing period. I downloaded the Nutec data monitor app. I use it as a "polygraph" of sort to manually monitor data at the source (phone). It has alerts set up for 50, 80, 100% warnings.

Iphone 5 using huge cellular data for push notification

iPhone 5 push notification using so much cellular data...how to fix this...plz help?
I am using iPhone 5 iOS 7.0.6. It's using so much cellular data for push notification. It's using 130 kb per hour...plz help me...I use only one yahoo mail account. I get everyday one or two mail..I don't use iCloud.. I don't have Facebook app...and I don't use skype..I have only viber app...I try to delete viber to solve this problem...but it didn't solved..I turned off push but nothing happen...I also erase all content and setting but didn't solve...
Plz help me...plz...
Plz it's hogging my callular data...plz anyone know how to solve this.

I've just spoke on the phone and with 3G activated it gets quiet hot,and with 3G off it gets a bit hot..
In an Italian iphone forum told me to restore it as new iPhone and try if it gets hot(they say it could be an application problem)
What do you think??

None of my iPhone apps are using cellular data except safari.

The problem I have is that none of my iPhone apps like skype, whatsapp, viber etc use cellular data !! But safari alone works using cellular data ... And I have a 3G data pack in my iPhone and I use it with safari alone ! So I know that my net pack is not slow .... Previously the apps used to work using cellular data ! But now I don't know what the problem is ... But it's not working ! I also did a general reset to see if the problem gets resolved ... But It doesn't help !! I have an iPhone 4S running on iOS7 !! Someone please help me with this issue ..

Then, your next step is to restore the phone. Unfortunately, I would not recommend you restore from backup. I'd suggest you restore as a new device, followed by syncing your content back to the phone:

You can "try" restoring from backup first, but if the issue is being caused by corruption in your backup, restoring from backup will merely restore the issue.

New iPhone user, 72-year-old lady, confused!

It's not like I'm a computer novice. I've been online since the days when a PINE editor was all there was. The web wasn't even conceived yet, let alone born! My first computer was a little Sinclair with 8K (later upgraded to 16K!). That was before Timex bought Sinclair. I got my first real computer (an Amiga) in the mid1980s. Most of you probably don't have a clue what I'm talking about because you weren't even born yet! I used Macs until my school system changed to DOS and ditched the Macs because some salesman from a company I won't mention "gave" the school a bunch of their machines in return for purchasing a software package that was ... never mind. I don't have time to tell you how horrible it was, and you no doubt could not care less. In spite of a long history of being much more tech-savvy than 99% of my peers, I am totally lost with all the new stuff!
1. My first question is about data usage - specifically "promotional data." When I checked my bill just now, it showed almost a full gig of promotional data. Is it data used by all those ads that come up?
2. There are lots of apps on the phone that I do not want. Is there any way to get rid of them? Am I correct in assuming that apps automatically update, and maybe that could be using a bunch of data? My grandchildren were appalled that I had used almost two gigs in two weeks since I don't watch movies, send videos, etc.
Here's what I have now:
an iPhone (5 something or other) which is totally awesome and which I am beginning to be able to figure out how to use
an Ellipsis Jet Pack which is my only ISP
an Android tablet which I bought after I killed my laptop with a spilled drink
a new Dell desktop with Windows 8 (without touch screen ) which I bought after I realized the tablet would not replace a computer. I took it out of the box and plugged it in. A screen came up that was so foreign that I got completely frustrated and decided to turn it off and get back to it later. I could not even figure out how to shut the thing off, so eventually just held the on/off button til the screen went black. I suppose I will eventually get it set up and try to figure it out because the Acer (see below) is on it's last lap
a more-than-ancient Acer laptop running Windows XP (used for web browsing, email, etc.)
Here's what I want to know:
If my Jet Pack is on and I make a phone call, does the phone go through the Jet Pack? If yes, does that use more data? (I have a plan with unlimited phone minutes and unlimited texts, so I'm wondering if I should be sure the Jet Pack is not on when I use the phone.)
Is there any way to stop those ads that come up automatically? Sometimes when I am playing Tetris on the tablet, either a Verizon video ad comes up, or I get a video in which Flo tells me why I should get Progressive insurance. I click the close button, and sometimes the video stops, but the audio continues until well after the game loads and starts.
Am I using data when I play Tetris (which I purchased)?
In short, what can I do to reduce my data usage?

I apologize for being so long in thanking you for your post in response to my question. I really appreciate your having taken the time to help me out. I have read a number of your other posts that have been very helpful, so that you for them, also!
I am between a rock and a hard spot it would seem. Several months ago, I got fed up with the ISP that is available at the RV park where I live. (I won't mention the name, because their customer service did everything within their power to help me. The problem with the poor signal is with the campground, I think.) I am located in a spot that gets a very weak or NO signal from that ISP most of the time.
When my laptop died, I was on the way to purchase a new one, and I missed the turn to get to Staples and the first place I could turn around happened to be a Verizon store. It occurred to me that I should look at a tablet and perhaps not buy another laptop. They sales pitches worked, and I got a tablet. When I told the salesperson that I was having trouble getting a signal, he suggested the Ellipsis, and I swallowed hook, line, and sinker. If I had known one tenth of what I now know, I would not own a Jet Pack.
The data usage problem still continues. I have turned off everything that it's possible to turn off. In fact, I turned off so many things that my camera disappeared! (Verizon customer service was able to help me fix that problem, but it took quite a while for them to come up with a solution.) I never watch videos or movies, and I spend no more than an hour (two at the most) a week on Facebook and LinkedIn. I do not listen to the radio or download music. I have data cut off so that images in my emails do not load automatically. I no longer send pictures in emails or upload them to any place. In short, there is no way on earth I should be using five gigs of data in a month.
What I thought was going to be a monthly bill of around $90 turned out to be closer to $150. I am considering taking your advice and turning the beast off entirely and getting another provider; however, I have a two-year contract with Verizon, and I think I still would have to pay the $10 per month access charge for the Jet Pack. (And who knows what kinds of other charges!)
I am not totally dumb, but Verizon's bills are truly conundrums to me. I THINK that I get charged for changing my plan when I tell them to up my data limit. (Not completely sure about that, though, because the format of the bill is so confusing.)
In all fairness, I must say that, without exception, all of the customer service reps have been wonderful. They have given me credits for inconvenience and even an extra gig of "promotional data." All of them have been extremely knowledgeable, not only about solutions to tech problems, but about billing problems as well. I have nothing but praise for the Verizon customer service department.
This afternoon, I started surfing around on this site, and it would appear that a HUGE number of other people are having the same problem as I am when it comes to sky-high data usage.
As soon as I get finished typing this, I am going to call to see what my options are with the Jet Pack. Will keep you posted. Thanks again for all your help.

Iphone 4 cannot use cellular data anymore after 4.2 update

I have an iPhone 4 and I have recently updated it to the latest o.s. after updating I can no longer use the internet without wifi and I cannot send/recieve picture messages (have tried to send and recieve with multiple carriers) and my phone sometimes does not recieve calls or regular txt messages. Please help.

It's weird, I'm having the same problem. Once I deactivate WiFi my iPhone 4 doesn't get 3G anymore, I have to reboot in order to get data back.
This is also after updating to 4.2.

IPhone 5 cellular data services failing

ISSUE/SYMPTOMS: iPhone 5 ONLY: Cellular Data stops intermittingly, cellular data locks up without warning, Wi-Fi data connection not working on occasion, iCloud contacts, calendar and reminders not updating, Find My Phone not working, mail or Internet not available or server time-outs. No error messages though. All of these are symptoms of no data service. Problems seem to be related to iPhone 5 failing to switch between LTE and 4G or 3G data services on AT&T.
My iPhone 5 32GB AT&T version (iOS 6.0.2) along with my clients and family using iPhone 5 in the state of Oklahoma are having this issue on their AT&T iPhone 5's: no cellular data connection re-established if at anytime the LTE connection is lost or weak. As with iPhone's prior to iPhone 5, the iPhone 5 is supposed to drop down to the next tier of data service and re-connect to cellular data service when the higher speed cellular data service is not available. Apparently this is not working well on the iPhone 5.
What led me to research this LTE issue was that my iPhone was not syncing on iCloud with contacts, calendars and reminders with my other iOS devices. Other times this issue became apparent was when iMessage quit sending and receiving until I would reboot my iPhone (sometimes it would finally send the message as a “text message”). When I had these problems I also found out I was not getting any cellular data service for Internet browsing, mail, Maps, Find My iPhone, etc. This would happen without notice. In other words I would not receive any notice or error message that data service had stopped other than the fact I was not receiving any mail, iMessages, or iCloud sync updates. My only resolution was to reset or reboot my iPhone several times a day, and that would resolve it about 70% of the time.
I have talked to Apple Support on 2-3 occasions in the last week and AT&T Support twice in the last 2 days. If it is really true, only the AT&T Technical Support Advisor informed me of a nationwide issue relating to iPhone 5 and LTE: iPhone 5's are not re-connecting to 4G or 3G cellular data service once the LTE data connection is lost or dropped... the voice calls continue to work, but cellular data service fails and stays locked up without an error message until the customer reboots the iPhone.
Obviously this is very unacceptable. We depend on these data services and at minimum need to know when it stops working instead of finding out from a phone call that someone sent us an important email or something.
The AT&T representative also said that both AT&T and Apple are aware of and are working on the issue as it is a nationwide problem with iPhone 5 and LTE. The Apple Support Advisors I talked to made no mention of this "known" issue. AT&T said that it is partly AT&T responsibility because the capacity of LTE is overloaded and cellular data connections are dropping because of the lack of coverage and/or capacity. They actually refunded my data service for a whole month in apology for the inconvenience (I did not even ask for that--I just want my data service to work). But they also said that Apple has responsibility in this issue because the iPhone 5 should drop down and re-connect to the next lower tier of data service when LTE is not available or lost; instead, it is locking up somehow or it still thinks it is connected to LTE when it is actually not. I don't know how accurate these statements are, but my problem is real.
TEMPORARY WORK-AROUND / FIX FROM AT&T: Disable LTE on the iPhone 5. Or when you figure out that data is not coming to your iPhone, use Airplane Mode ON/OFF for a few seconds to force re-connection to a tower without rebooting the iPhone. You can Disable LTE on the iPhone 5 in SETTINGS/GENERAL/CELLULAR. I have disabled LTE on my iPhone 5 and have not had any of these cellular data issues since.
Disabling LTE is not acceptable either, but it is working. At least I seem not be losing connection or locking up without knowing it. In my office over the course of a day, my iPhone 5 will jump back and forth on LTE and 4G sitting in the same place. Disabling LTE has stopped this and the problem, but the iPhone 5 should switch cellular data services seemlessly just like the phone switches towers on a phone voice call seemlessly (most of the time).
WI-FI ALSO STOPS WORKING SOMETIMES AFTER THIS LTE disconnect / lock-up issue: That has been my experience along with my clients and family as well. If you use Wi-Fi a lot on your iPhone it will hide this LTE issue until you leave your Wi-Fi and get on LTE and then drop LTE (silently) and then go back to your Wi-Fi. My experience has been I have to reboot the iPhone to even get Wi-Fi working again after that happens.
I do not know if some of these comments and analysis are really accurate or valid or not... all I know for sure is since I upgraded my iPhone to the 5 along with my other family members and clients, we have had "no data" on many occasions and are continually rebooting our iPhones and looking for what is wrong.
My questions to the support community are these:
     1. Is anyone else having this issue? Or is it just me and my few? Maybe a lot of people do not realize they are not getting their data because they are on Wi-Fi most of the time or they are just rebooting and not trying to identify the real problem. AT&T said it was nationwide iPhone 5/LTE issue. Anyone else heard that from either Apple or AT&T?
     2. Is this an iPhone 5 / Apple issue or is AT&T solely responsible? Or is it both? Where do we get a solution??? Is AT&T LTE holding false connections with iPhone 5 or is the iPhone 5 failing to recognize a dropped LTE cellular data connection and then failing to attempt to re-connect with 4G or 3G?
     3. Did I miss where this issue is posted? I searched Apple Support and Communities and did not get any hits. Any updates or further insight on the issue? Any other fixes other than Disabling LTE?
      4. If this is in fact a real issue belonging in part to the iPhone 5, we need to escalate Apple’s attention to it.
Thanks in advance for your help and feedback.

Thank you fellow users and experts for your feedback and updates. Sorry about the large font on the original post... accidental via cut and paste.
I have escalated the issue with both Apple and AT&T. I actually got senior level troubleshooters from both Apple and AT&T on the phone at the same time... rare moment. Here are the key points of the update:
     1. AT&T did NOT confirm the earlier statement by another AT&T Technical Support Agent that this was an emerging nationwide issue about iPhone 5 and LTE losing data connection and not reconnecting at a lower level or re-connecting to LTE once the signal came back. So that earlier statement was not accurate as suspected by all of us. The senior tech at AT&T said he has seen this issue sporadically over the last month or so, but only with about 3-4 customers. He said it seems to be location or phone dependent (some phones not all phones).
     2. The Apple Tech was satisfied that all that could be done to eliminate my issues possibly relating to my instance of software / iOS had been accomplished except erasing my iPhone and restoring as a new phone (I have avoided this inconvenience with the argument that other family/clients with the iPhone 5 have had the same problem).
     3. AT&T went so far as to examine which towers I had been connecting to over the last week and looked at other technical data that could possibly explain the issue. I now know I have 3 towers that provide LTE within 4 miles of my home/office, one within a half mile. But so far there is nothing to explain or even properly identify the issue. AT&T offered me to take my phone to an AT&T store, try to force replicate the problem there, if so, the store would put my SIM card in a brand new iPhone 5 (just to test) and try tor replicate the problem again. If replicated on a new phone, there is a deeper issue; if resolved on a new phone, the answer is obvious. I have not taken the time to do this yet.
     4. On Friday, Jan 4, 2013 while talking and between the tech support calls (on a different phone), I was able to re-create the problem 2 separate times in my home/office by forcing my iPhone to weaken its connection to service (burying it under electronic gear) and then waiting a few minutes, then trying to browse the Internet--no data service unless I manually reset the connection. I am only able to cause the issue to occur if there is at least 15 min of idle time after a weak signal condition AND only if I don’t completely lose a connection to cellular voice service. It seems that if you go down to NO SERVICE the phone will do new a search and keep searching until reconnects to LTE or other signals correctly, but a weak connection seems to be strong enough for voice service but can sometimes cause the LTE data service to stop without reconnecting to LTE, 4G or 3G unless I manually intervene. It also seems that idle time with a weak connection is also necessary to re-create the problem manually. Since Friday, I have not been able to re-create the problem. This has been an intermittent problem, so who knows.
FYI, I have never had this problem with my new iPad (also on AT&T LTE) that has been with me when the iPhone fails to have data service, but my iPad is never in my pocket or other places with perhaps less signal.
Again, if you are connected to Wi-Fi on your iPhone 5 most of the time, you may never notice this issue if you are even having it.
So far no progress on the real issue or resolution, but both Apple and AT&T have put forth very admirable effort.
If you or others you know are having this issue, please take the time to post a reply to this issue. Thank you.

How do I get my iPhone to stop turning on cellular data for apps on its own?

I have tried resetting on the iphone and resetting all settings. Nothing seems to be working. So far the only improvement is that my iphone stopped turning on cellular data for other apps but now, interestingly, it's turning on cellular data for all apple designed apps,e.g. Pages, App Store, Itunes Store, Facetime, Contacts, Calendar, Mail etc. Everytime I try to turn them off, it doesn't work. Please Help!!
P.S. My phone is running ios7.

Follow these directions, but pay attention to comment 1 regarding drafts. Best instructions I've seen on how to set gmail up as IMAP.

HT1688 I have an Iphone 3gs. When I go to Settings, then General, then Cellular, only Cellular Data and Enable 3G appear. There is no "Roaming"option to turn on or off. When I first started using the phone there was and I turned it off. What can I do?

I have an I phone 3gs. When I go to Settings, then General, then Cellular, only Cellular Data and Enable 3G appear. There is no Roaming"" option to turn on or off. When I first started using the phone it was there, and I turned it off. Why is it no longer there? What can I do to get it back? I am being charged roaming charges!!

My iphone 4s has the Cellular Data and Data Roaming but does NOT have the option of ROAMING Voice&Data. Do you know how to enable it?

Why do i have to restart my iphone 4 to connect to cellular data network after moving out of wifi range?

Whenever I move out of a wifi zone, I expect my iphone to connect to cellular data automatically. But this doesn't happen. I have tried turning flight mode on/off and also tried turning cellular data on / off couple of times, but nothing works.
I only get the cellular data connection back after I restart my iphone.
I started having this problem after upgrading to iOS7.
Any idea how to fix this?

Hi beingkejo,
Thanks for visiting Apple Support Communities.
Toggling Airplane mode and cellular data are good troubleshooting steps. If your iPhone still does not connect to cellular data automatically when Wi-Fi disconnects, I recommend the additional steps in this article:

What are mapping services and why they use so much cellular data?

I previously had an iphone 5 and my monthly cellular data consumption was about 250MB.
I recently switched to an iphone 5S and the cellular data usage is about 250MB per week!
I try to monitor and reduce the usage but the mapping services in system services is always very high!
What is this? Can I reduce it?

Mapping Services ( story ) :
In April 2011, iPhone and iPad users were surprised to discover that, not only was their device keeping track of where they’d been, it also was storing very detailed location information in a plain-text file on the phone. The data was derived by the cell towers and Wi-Fi hotspots the devices encountered, and was added anonymously to a crowdsourced database.
Apple later said the devices were keeping more information than intended due to a bug, and issued a patch that reduced the amount of data. But, because it was used to improve and speed up location services, the practice continued.
And now, in iOS 7, Apple has added a tool that lets you see what your iPhone knows about where you go.
If you’ve got an iPhone 4S or later running iOS 7, follow these steps:
1. Go to Settings, then Privacy > Location Services.
2. Scroll to the bottom of the list of apps that use Location Services (and feel free to marvel at how many apps do!). Tap System Services.
3. Tap on Frequent Locations, then scroll down and look at History. You’ll see at least one city there, more if you travel.
4. Tap a city. You’ll see a list of locations you’ve visited in the city.
5. Tap a location. You’ll see a list of the dates and times you visited that location.
Why in the world would Apple collect this kind of detail about your movements? It does so to enable features like Next Destination, found in the Notification Center, which is the screen you see when you swipe down from the top of the iOS display. Next Destination looks at your travel patterns and offers information about how long it will take to get to the next place you typically visit during the day.
If having all this location data collected by your iPhone makes you nervous, you can turn it off at Settings > Privacy > Location Services > System Services > Frequent Locations. Note that it is turned on by default, so if you don’t want your phone logging your whereabouts, you’ll need to turn it off.
The Next Destination feature is similar to one found in Google Now, which uses location and your habits to offer up useful information without your asking for it. Google Now is found in the Google Search app on both Android and iOS. On Android, you can add a Google Now widget to your home screen to make the feature more accessible.
In fact, Google collects similar information about you – and in greater detail - if you use its location-based products. Google stores your location data on the Internet, and you can see it on any Web browser.
Make sure you’re logged into your Google account – say, through Gmail – and then go to google.com/locationhistory. You’ll see a map showing location visits for today, but click the Dashboard link at the top of the page and you’ll see this:
To turn this off, click the gear icon in the upper right corner of the Location History page and choose History Settings. Then, click Disable and Save. There’s also a History Management link that lets you delete history items that have already been collected.
Location services are really an integral part of a ton of iOS apps, using the internal GPS system to add Instagram photos to a map, checkin with FourSquare or Facebook, or let your friends know where you are with one of many “on my way” apps, like Glympse or Twist.
If you’re battery is dying, however, the location services are the first thing you should turn off, as they suck up a lot of your iPhone, iPad, or iPod touch’s power needs, what with their background data sending and receiving and such.
Here’s how to turn them off.
Tap your Settings app to launch it, and then tap on Privacy. You’ll be able to turn the toggles OFF for any specific app that has privileges to access your GPS location by scrolling through the list and tapping them all. I do this on a fairly regular basis for both privacy and battery savings. I figure that with less apps accessing my location, the less battery power in total is being used for that function.
If you want to turn off Location Services completely, then simply tap the main toggle at the top to OFF, and you’ll stop using them. This will keep your apps that need it, like Maps or Compass, from knowing where you are, but the battery will thank you.
Follow the above steps to turn off Location Services :

Verizon iPhone 5 Update Fixes Cellular Use on WiFi Bug

If you have been seeing higher cellular data usage while you are on WiFi, good news, Verizon has fixed this bug. All you need to do is update your Carrier Settings to 13.1 and the bug is fixed.
For directions on how to update your Carrier Settings, see:
Verizon iPhone 5 Update Fixes Cellular Data Use on WiFi Bug - EVDOinfo.com
Be interesting to see if this fixes the issues for all those having the problem

I have the exact same problem!
I'm using the iPhone 5 now under Carrier M1 Singapore 13.0 and I have noted that over a period of 2 weeks, my cellular data usage has been about 2.7GB on an average. Since I know my bill has been capped at 3GB, I have since switched off my cellular data.
However, when I switched it on for a few days after using it for awhile, my cellular usage jumped by 1.2GB in just 1 day! And I used it as I would on an average day (like during an average day in the 2 weeks)!
I understand that there have been reports of a bug that have caused this problem in the US.

http://www.iphonehacks.com/2012/10/iphone-5-cellular-data-usage-over-wifi-bug-on -other-carriers.html
But I'm hoping that there's a solution for those living in Singapore? Do I seek the help from my carrier as well? But if it's a problem with the phone, then my carrier definitely would not help, right?

Settings button (action) is on the left had side of the Cellular Data is Turned Off notification message put up while the OK button is present on the right hand side of the notification

The defualt notification message put up when launching iTunes on iPhone devices show that Cellular Data is Turned Off message is put up with Settings and OK button.
This seems to be inconsistent with the default 'Cancel' and 'Action' buttons in other notification messages from Apple.
Is it fine to consider the OK button first (left) and Settings(right) button next in the Cellular Data is Turned Off error message in the apps so that it is in line with the apple guidelines??
Please help with this.
Thanks you so much.

Try the basics from the manual. Restart, reset, restore.

"Could not activate cellular data network" message after ISO 4.1 update

I updated my iPhone yesterday just like millions of other people, but since the update was completed, I haven't been able to use the data network. Wi-Fi works without any problems, but when I've been out of the house yesterday and today, I haven't been able to establish any connection to the data network and have received the "Could not activate cellular data network" message each time. Is anyone else having this issue too? So much for a flawless update.

Hi,
This happens to me everytime I do a f/w update but for me its for a simple reason and is easy to fix.
I am using a non iPhone Contract SIM in my iPhone and as such is does not like the default iPhone contract APNs for cellular data, hence the message. These reset when you do a f/w upgrade.
I have to go into Settings/General/Network/Cellular Data Network and set the APNs (for data and MMS) to ones given to me by my provider, in this case O2 UK for a non iPhone SIM/Contract - all is then well.
Perhaps you are in a similar situation ?? It shuold be easy to resolve by checking the APNs for your SIM against the ones in the iPhone itself. I found mine by Googling for iPhone O2 APNs. In fact in the end O2 published the setup on their website.
Hope this helps.
Radar.
