iPhone 5 Cellular Data Usage Over Wi-Fi Bug May Be Also Affecting Users On Other Carriers

iPhone 5

Yesterday, Apple released a Carrier update for Verizon iPhone 5 to fix an issue where cellular data was being used while connected to a Wi-Fi network.

9to5Mac reports that the issue may not be limited only to Verizon iPhone 5 and my be also affecting users on other carriers.

9to5Mac reports

We received multiple reports of the same issue from AT&T customers, indicating the problem might be related to iPhone 5/iOS 6 rather than Verizon-specific.

As noted in the tweet above, like Verizon iPhone 5 users, some AT&T customers experienced hundreds of dollars in overages. One iPhone 5 user reported gobbling up to 2GB of cellular data over a three-day period while connected to Wi-Fi.

This thread on Apple Support forums also indicates that the issue may not be limited to Verizon iPhone 5. The New York Times has also reported that the problem may affect iPhone 5 users on other carriers as well:

the problem may also affect iPhone 5 owners on other carriers, including AT&T and Sprint. Those two carriers and Apple did not immediately respond to a request for comment.

But it also possible that just like 4G LTE iPad users, iPhone 5 users are burning through their monthly data limits quickly thanks to the ultrafast 4G LTE speeds.

Anyways, it may be a good idea to check the cellular data usage on your iPhone 5 to confirm that you’re not facing the issue by following these simple steps.

  • Launch the Settings app
  • Tap on General
  • Then tap on Usage
  • Scroll down and tap on Cellular Usage

You can check the cellular data usage under Cellular Network Data and compare it with your cellular data usage prior to buying the iPhone 5.

Let us know if you’ve noticing unexpectedly high data usage on your iPhone 5.

    I have 1.1GB over 1 week of use and have not used any data intensive apps.

  • Dave Swartz

    I was initially concerned seeing High usage listed under settings usage. Checking directly with AT&T I found my usage was normal. Appears to be only a problem in the data usage statistics on the iPhone.

  • vlaine

    I checked my data and there is a bug.  My data usage is mostly done by tethering with my Ipad.  My data is : sent 314 mb, received 1.1 gb.  This is way more than my real usage.  My tethering data should be almost the same but it is not: sent 32.8 mb, received 361 mb.  This is my real usage.  I think I need to give a call to Rogers.  Rogers says I used 452mb in the last 5 days.  None sense!

  • Mike

    600mb in 4 days so far. Something is wrong with AT&T iphone5 customers as well. I hope they send out a fix soon

  • http://twitter.com/ronmora Ron Mora

    After 9 days I have 125 MB sent and 5.4 GB received. And I received a text from AT&T after 6 days I was reaching 5 GB of usage. I’ve been using the iPhone since 2007 and never been near 5 GB.

  • Paul Graham

    It is most definitely leaking through my WiFi with my iPhone 5 on Rogers in Canada.

    not a bug its built in feature to use fastest connection available”.”

    • JCT

      its a setting called “Wi-Fi Plus Cellular” if you turn that off will disable the feature which apple put on to satisfy people speed need dont know if GM ios6 has the off button build in developer did

      • vlaine

        Wi-Fi plus cellular shoud be : use cellular only if Wi-Fi is not available. Currently, cellular seems to override Wi-Fi.

        • sj

          neither…whatever connection is faster is the one that gets preference.

        • JCT

          it dose not matter what you think it should be only matters what is and the is feature using up your data, also your idea makes no sense as that has always been the way so why add off button for that

    yea me and my roommate both got one. I have AT&T and didnt have any overages but my roommate has Verizon and had downloaded 6.2 GB in 7 days! what is the phone doing with that much data!?

  • Renzod

    Could this be a problem with iOS 6??? I’m using a 4s and I supposedly used 4.7 gbs in two weeks. When my average is 3.2 in a month

  • chungpham2004

    so much for a revolutionary product… i guess iphone users just have to shove-it-up-their and move along… don’t forget to pay the charge though…lol

  • http://twitter.com/Israelfox Israel Corona

    2.1 GB in two days lol AT&T iphone 5 lol unlimited data do

  • Bigflow76

    I got AT&T I’m testing it. So far no problem

  • srdesch

    My ATT App shows much LESS Data usage than my iPhone’s internal usage report. I use an iPhone 4 with iOS6. The iPhone says I’ve used 5.6Gb Sent and 82.2Gb Rec’d !!! My ATT app says I’ve only used a little over 1Gb so far this billing cycle (13days)
    I sure hope the ATT App is correct!

    • srdesch

      These high figures might be my LIFETIME figures since it says “Last Reset:Never”

  • Serf

    I’m with Rogers in Canada I’ve used 4.5gb in 10 days the most I’ve ever used was 2gb in one month. The iOS is the problem

  • Serf

    What is the new iOS using all this data for. Is it location service or just background apps

  • Serf

    LTE is not the problem it dosnt use more data it just gives u faster data so yes you might use more cause its faster so u can surf more but it’s not using more data.

  • vlaine

    Got it. I am almost sure I know where the problem is. In the section General/cellular/Use Cellular Data For I had everything On but Itunes. My understanding was that cellular data was allowed for these applications. What it seems to do is “override WiFi and always use cellular data”. If I am right, the Facetime I tought I did in WiFi was done one LTE and now my Data usage fits my stats. I turned off everything for further testing. If I am right, I hope they fix it quick.

  • Rayanthony10

    Yep same issue here also with AT&T

  • Interesting

    Could it be that WiFi connection is not steady or that 4G LTE over-ride the slower WiFi? I have the iPhone 5 since last week, beside the first day, i have not gone outside of my home’s WiFi network but yet, my cellar usage goes up a few meg each day?!?!?!?

  • dankvwguy

    Ive had my 5 since the 21st and used over 2GB of data. ive streamed a few things and listened to pandora a little but when i did it on my 4S it only used a few hundred mb a month. Something seems to be wrong.

  • http://www.facebook.com/profile.php?id=1740590440 Abel Goddard

    As of yesterday around 1:30, my ATT app said just over 5gb in 10 days. My average is somewhere under 2gb in 30 days, I think. I checked after it became super clear that ATT was throttling me. Punks. I’m grandfathered into unlimited…

  • Amar

    yes.. i have at&t and im seeing that i have used more data when it was connected to WIFI as well.. I remember that i was on wifi on sunday morning at home but when i logged into my at&t account, it shows i used 20 MB and 200 MB etc.. i was watching espn at that time over wifi..

  • http://portotype.com/ H. Ayres Pereira

    7Gb in a week on Optimus@Portugal

  • Boringpie

    I have a 4s on ios5, but since last month my iPhone has been using 2Gb a day consistently over wifi even if I left it alone. After a week 20Gb was used and I got charged big time by my wifi provider.

  • Dncollins

    I am having the same issue!!! I got an iPhone 5 on att and have used 65 percent of my data limit in 8 days…I typically average 2 gbs over a 2 or 3 month period mostly wifi.

  • MStew

    Same issue here, except it is on a 4s/iOS 6/ AT&T

  • seaslug

    It appears that I am also experiencing much higher usage than previously, on AT&T. Unfortunately, my evidence is highly anecdotal. However, I will point out that I’ve been on a train for well over the last 24 hours, with a lack of cellular access of ANY kind for some parts of the journey, as well as no usage by me, overnight. There is no way I could have used the 511 MB listed for that time period. I’m sure the bug exists for AT&T users as well.

  • milad

    1.6 Gb in just 5 hours!!!! Just listening Pandora for 1 hour!!
