Cellular Data Not Working in iOS 9 on iPhone or iPad? 6 Troubleshooting Tips

Cellular data not working in iOS troubleshooting tips

A number of iPhone and iPad users have discovered cellular data usage is failing to work after updating to iOS 9. The cellular data problem is typically manifested in a few ways; either an outright failure to transmit any data or access the internet whatsoever when the iPhone or iPad is connected to a cellular network (though wi-fi continues to work), a failure of certain apps to connect to mobile data or access cellular data, or, in some situations the Cellular Data button is disabled but grayed out and unable to be toggled on.

If you are experiencing cellular data transmission or mobile connection issues in iOS 9 or any of the iOS 9 point releases, you may be able to resolve the issue with some troubleshooting tips we’ll outline below.

0: Update iOS to the Latest Version

The first thing you should do is update to to the latest version of iOS. In fact, iOS 9.0.2 is specifically aimed at fixing this problem with cellular data. If you haven’t done that, do that first.

Go to Settings > General > Software Update and when you see iOS 9.0.2 (or later) available, install that first.

When the iPhone reboots to the latest version, the cellular data should work just fine. If not, continue on with the troubleshooting steps below.

1: Confirm that Cellular Data is Enabled

I know this sounds obnoxious, but double-check your general Cellular Data settings in iOS before anything else.

  1. Open the Settings app and tap on “Cellular”
  2. Toggle the switch next to “Cellular Data” so that it’s in the ON position
  3. Scroll down in the same Cellular settings screen and be sure apps you wish to use with cellular data are turned ON as well
  4. Exit out of Settings

For some users, they may discover cellular data was turned off, or that cellular data was turned off for specific apps. If you’re only able to connect to the internet with wi-fi and unable to access mobile data, this can often be the reason why.

Obviously if the Cellular Data button is grayed out you’re not going to be able to do this, and if that’s the case, or if you tried this and mobile data is still failing in iOS 9, then continue on.

2: Reset the Device Network Settings & Reboot the Device

The next troubleshooting step is to reset iOS network settings, and then turn the iPhone or iPad off and back on again. This can often resolve cellular data failures and it’s pretty simple:

  1. Open the Settings app and go to ‘General’ followed by ‘Reset’
  2. Tap on “Reset Network Settings” and enter the passcode to confirm you wish to reset and clear out all network settings on the device – this will ditch wi-fi networks so be prepared to enter wireless network passwords again
  3. Exit out of Settings and go back to the Home Screen
  4. Now hold down the Power button and turn the iPhone or iPad off
  5. Wait about 10 seconds and hold the Power button again to turn the device back on

When the device boots back up, try to use an app with cellular data again. It should be working at this point, but if not, read on.

3: Check for a Cellular Carrier Update

Cellular carrier providers will sometimes offer updates to the iPhone to increase compatibility with their network. You can check to see if a cellular carrier settings update is available by going to Settings > General > About, if you see a pop-up message offering to install a cellular carrier update, install it.

4: Update iOS to the Newest Version

Sometimes simply updating the system software will resolve the cellular data issue as caches and some basic iOS maintenance is performed behind the scenes during a software update. Be sure to update iOS 9 to the latest version available. If you’re on iOS 9, that means updating to iOS 9.0.1.

4b: Consider the Beta Releases

A bit more risky, but you can also sign up to participate in the public beta program and jump to beta versions of iOS. Be warned though, beta software releases are notoriously buggy and tend to be less reliable. This is really only appropriate for more advanced users, but making a jump to iOS 9.1 beta may resolve the issue, assuming you can tolerate the beta experience.

5: Backup, Perform a Factory Reset, & Restore

This can be a long process depending on the size of your iPhone or iPad and how much stuff is on there, so don’t start this if you don’t have potentially several hours to complete it. Annoying, I know. Nonetheless, resetting a device to factory default settings and then restoring it with a backup can often remedy peculiar situations. Absolutely backup first or you will lose data doing this. You can speed it up a bit by backing up and restoring from iTunes with a computer, which tends to be quicker than using iCloud backups, but use iCloud if that’s what you have available.

  1. Connect the iPhone to a computer with iTunes, select to encrypt the backups (encrypting backups saves passwords set on the device, and allows you to restore your health data), and choose to backup the device
  2. When the backup has completed to iTunes, perform a factory reset on the iOS device by going to Settings > General > Reset > Reset All Content & Settings – this erases everything on the device so absolutely do not do this if you have not completed a backup first
  3. When the device has been reset and is booting up again as if brand new, go through the normal setup process and choose to restore the device from the backup you just made

Once the iPhone or iPad boots back up again, try to use cellular data. It really should be working at this point. In fact, the reset and restore process is often what Apple will instruct you to do if you call their tech support line with this issue, because it’s usually effective.

If your cellular data is still not working after a complete restore, your options are becoming a bit more limited, and you may to try setting the device up as new (without restoring), or you may want to downgrade to a prior release while it’s still possible.

6: Still No Mobile Data? Consider a Downgrade

An iPhone is obviously less useful without the ability to use the internet and transmit data over a cellular network, so if you find yourself unable to find a resolution with the above troubleshooting steps, you may want to consider downgrading iOS 9 back to iOS 8.4.1 as described here. It’s a somewhat technical process, but it is effective if you had no issues with the prior system software. Keep in mind that you will only be able to restore an iOS 8 backup to iOS 8.4.1, so you may lose personal data if you choose to go this route. On the plus side, leaving iOS 9 remedies any slow performance issues with iOS 9 if you have been experiencing those. Be sure to make a backup of your device before attempting to downgrade.

  8. Peter says:

    I had the same problem. The Apple Store Genius worked out that the bug is in the Restore. You have to Reset and start from new again. Dont Restore because you bring back the bug that prevents you getting Data. The icloud contains Profiles that are nasty.

    • Devamon says:

      Your iPad 4 is connected to wi-fi, that is what you should do if cellular data is not working. Take it to your cellular store and ask them to fix it. They are the experts, the cellular experts at your store you bought iPad from. The cellular data requires the mobile carrier.

  14. Opemipo says:

    I’ve had the same issue since I got my iPhone 6s, 2G works fine but 3G doesn’t work, it overheats the phone and shows no network most of the time. I’ve restored my phone to factory settings before and it didn’t help. Any suggestions?

  15. Sanya says:

    I meant in the last comment with 3G I could not do any web surfing and texting.

  16. Sanya says:

    Thank you so much! Because of this website my internet data connection is resolved . At first it went to 3G when I have LTE and did not change and I didn’t know what to do . With 3G I could text or surf the web . Thanks again to you my data internet is fixed!

  17. Casa says:

    1: Confirm that Cellular Data is Enabled
    I know this sounds obnoxious, but double-check your general Cellular Data settings in iOS before anything else.

    Not obnoxious at all. I would have started there if General > Cellular Data existed. It does not nor does Personal Hotspot. So much for ease-of-use Apple. I miss Jobs.

  18. raman kumar says:

    dear admin
    i am also facing the same issue since morning, unable to connect any social app whereas the LTE & 3G is connected and network is full.
    i tried many times to turn off /on , eject sim, restore network settings.put problem is still same

    kindly help

  20. AUSTIN says:

    Where is “cellular”? it’s not on the settings on my phone

  21. Bryan says:

    I have an iphone 5s i have done everything.

    -reset everything/ wiped everything
    -messed with the region and time settings
    -Reset phone setting and data
    -talked with apple basically told me , they cant help me
    – no service 9.1 and was on 9.2 and it still did not function.
    -im sure there is no hardware problem i have overlooked in the guts and replace the charger port where the cellular signal is transmitted
    -i have and ipod touch and paying a phone bill that doesnt apply to it
    -This is bs. i dont understand apple why waste my time and money anymore.

    • utna says:

      Maybe you forgot to pay your bill. Call your cell phone provider, some cut off service without notification to you. Probably has nothing to do with iPhone, it’s maybe your cell network.

  22. Linda says:

    Thank you! The reset network has fixed it I think! My issue was it wouldn’t recognise cellular data for iMessage kept saying it wasn’t on and to use wifi. After resetting network it seems all good!

  23. Ayden says:

    I turned off the LTE on ios 9.0.1 and it worked.

  24. Denis says:

    I solved the problem enabling LTE and disabling roaming data. Many days in trouble after update 9.02 on iPhone 5S.

  25. Mehmood says:

    Thanks, it helps me and solved my problem only at point 2,
    just one more step added in this “I enabled DATA-ROAMING” and its working. :)

  26. Artem says:

    In my case the problem was solved this way: turn off your iPhone -> eject SIM-card -> turn on -> turn off -> insert SIM -> turn on – and everything works! I think it’s problem with detecting SIM or something… <_<

  27. Brad says:

    Yep…disable LTE.
    Problems went away.
    Hey APPLE…get it?
    When are we going to get iOS 9.2????? to fix this $h!t ??

  28. Tawfik says:

    This article helped me! Thanks a million :)

    Evn i m havin same problm i cnt use cellular as 3G….tried evrythin bt its useless…sud i switch to android…

    • Wow says:

      Wow your iPhone vowels keys aren’t working? Wow that’s amazing. Did you reset network settings? That would be the first thing to do. That should make your iPhone vowels work. I don’t know about how you would use Android on an iPhone I think you may be wrong there.

  30. ntan says:


    My device is iphone 6s plus 128gb.

    Just updated it to 9.1 from 9.0.2 and now i am unable to connect to Airtel 3G in india.

    tried resetting the network settings.
    Erased iphone and restored from itunes backup.
    updated to latest carrier update settings to Airtel 22.1

    nothing works.

    please help.

    • Harsh says:


      I also updated my iPhone 6 to 9.1 yesterday only.

      I am seeing lot of network issues. It remains No Service most of the times. Mine is also Airtel 22.1 now.

  31. Raul says:

    (UPDATE) My cellular data with Metro PCS is back! I followed the advice of someboy from a different forum. Here is what I did:

    1. Updated iTunes on my computer to the latest version.
    2. Tried to go back to 9.0.1 but it didn’t work. iTunes said my iPhone was not eliglible for that.
    3. Reinstalled 9.0.2 just to see what would happen.
    4. Selected to restore from a backup I did in June.

    It took a while but now it works. Good luck everyone.

  32. Raul says:

    I have been on Metro PCS with my iPhone 5 for a few years. Everything was fine. After upgrading to ios 9.0.2 my cellular data doesn’t work. Cellular Data Network doesn’t show on this ios anymore and after talking to a metro pcs agent, it seems that they don’t even know that. They can’t help. Since they don’t have a solution in hand, they just say that iPhone is not supported by Metro PCS. Apple doesn’t allow to jump back to the previous ios, so now we are all stuck with a phone that doesn’t connect to the internet. Anybody found a workaround? Thanks.

  33. Karolina says:

    There is a software update now that fixes this issue.

  34. Jamie says:

    This update worked had prior update on iPhone 3 and couldn’t get app. Data to stay on . I could click it on and when I exited out of settings it would shut back off

  35. Steve says:

    I am 9.0.2 and still can’t get access to apps while on cellular data which means my personal hotspot won’t work either. The tec at Apple was no help.

  36. Dennis says:

    I too have been without cellular data since iOS 9. I have updated to the latest and same issue. Full factory restore without restoring from backups and same issue. Did a recovery restore and same issue.

    I’m a registered developer and installed 9.1 beta 3 and still no cellular data.

    I’ve exhausted all options and now hate my iPhone 6. I’ve lost all faith in Apple iPhones at this point. Just ordered an unlocked Nexus 6 and will go back to Android where I never had any issues (so far).

    If Apple will allow us to go back to 8.4.1 then I would stay with my iPhone but they have stopped allowing that.

  37. Alan says:

    Similar problem with my wife’s phone Vzn provider. Phone was working fine with the 9.0.1 ios for 5 days. Suddenly Oct 1 at about 1100 am it stopped working for cell data. Phone would only work in 3G mode and would not use any data unless connected to WiFi. Contacted apple; they had me reset network settings, turn off cell data, put phone into airplane mode and turn off phone. On restart everything turned itself back on. The next step they gave was to restore phone to factory and they will call me back on the 2nd. After I did the restore the phone now will not connect to my wireless carrier at all. Looks like I will be banging on the Apple store door at opening to get them to fix or replace the phone.

  38. Pallop says:

    I experienced the no cellular data after downloading the IOS 9.0.1 so I called T-Mobile and they told me to get help from Apple.
    The lady from Apple told me to factory reset my iPhone 5 by first back up everything to iTunes (what a mistake!), it took more than 5 hours and nowhere near finish. I decided to stop the iTunes and back up everything to my computer (which took less than 30 min.) and reset .
    The problem still persisted so I decided to give T-Mobile another try.
    A T-Mobile tech man in Colorado Spring tried step by step different process and came with the solution!


    it works, but you only get 4G speed.
    I updated to IOS9.0.2 today and it did not resolve the problem, well..better than nothing! GLTA

    • Rachel says:

      Thank you! My mom has had this issue with her iphone 5C for more than a year. I just fixed it with your solution. Thanks for your solution! Rock on!

  39. Robert says:

    I’m running 9.0.1 on a iPhone 5. Cellular data works on some apps (like Facebook) but in others it turns it off for that app even after I’ve manually changed the setting. There are also some delays when unlocking the device and between apps. Makes me sad :( I really loved my iPhone 3 before it was pushed out of existence.

  40. Kinawa says:

    I just update my iphone 5s to ios 9.0.2, the wifi and cellular data getting worst. I have to restart my device often and its so annoying

  41. MB says:

    Thank you for posting that 9.0.2 was out. I was having the same issues as above, which brought me here, and now it seems to be fixed since installing it.

  42. Frank jannuzi says:

    9.02 just released…claims to fix problem. But of course requires wifi connection to download….has anyone tried it yet?

    • Paul says:

      I am running iOS 9.0.2 and it appears to work fine with the cellular data, it has fixed that bug.

    • Carol says:

      I have 9.02 and it did not fix the problem. trying to install 9.03 but won’t over wifi. still says I am not connected to internet

    • Carol says:

      I have 9.02 and it did not fix the problem. trying to install 9.3 but won’t over wifi. still says I am not connected to internet

  43. Phyllis says:

    Thank you for your suggestions here. I’ve spent several hours today reading, looking for help for the cellular data issue. When I looked at #3 again re software update, I saw that Apple just released 9.02. Sure hope this works. Downloading as I type.

  44. Alex says:

    Since I upgraded two iPhones (5s and 4s), I am having issues with roaming data transfers charged despite roaming data in turned off – issues continues after the 9.0.1 update.

    I have had to restore the two iPhones within iTunes and with no backup restoring to fix the issue.

    What a mess.

  45. CC says:

    My cellular data apps keep switching back to off position. I tried back up restore, reset even waiting 3 hours at Apple Store. Don’t waste your time going to the Apple Store. They will not replace your phone because it is a data issue and you have to wait for the next iOS update to come. Contact your cellular carrier and tell them that you need a credit for each day that you cellular data is not working

  46. JAM says:

    couldn’t get cellular, went to Verizon they couldn’t fix, kept doing soft resets and turning off and on. NOW just get a loop asking for password, language, country and repeat over and over. Can make emergency call, maybe, but absolutely nothing else. I know part of the problem might be that I have too many pictures but recently it wouldn’t let me delete any, and out of storage.

    any suggestions or is this thing dead!? thanks if so!

  47. Michelle says:

    I tried everything but the only one that worked was deleting my iphone. Yes, delete everything and when it starts up, don’t back up anything. Instead, before you erase ur iphone, transfer every important files to your computer or ipad, etc. and then just transfer it all back after you erase your iphone. Create a new icloud account when u start up ur phone and then data will work in every apps again..

  48. Skullflower says:

    I just bought my iPhone 6 about 2-3 months ago right before they announced their 6s because my iPhone 4 finally gave out and since the new update like the latest one, I have no more iOS update options, I’m having major problems with it connecting to cellar and also wifi so really all I have is an iPhone that sends text messages not even iMessages and will make phone calls, I can’t use any apps, I can only listen to half my music when I’ve downloaded every song into the actual phone… I’ve done all these steps and it still has the same problem, Im sorry but for a $600 phone it works like complete crap and I have never been more annoyed or disappointed by an apple product in my life and as someone who needs their phone for school and work it’s even more frustrating to have an unrelaiable phone that wasn’t cheap, I have to say if they don’t fix their crap soon, I’ll be taking this phone back even if I don’t get my money back and buying a Windows phone. Apple is not the same anymore- instead of making reliable devices that last and work to their best, they’re just racing to have the newest phone out there, even if they only work half as good as they’re suppose to which is bullsoot for the prices we pay.

  49. KYAW TUN says:

    Now I should be change To Android phone , after update IOS so many problem under 4G service all my applications are fail to work! What going on such as Email , free txt & call . I only can say that this Apple products are too expensive but useless . Conclusion we can not say that it is good & best smart phone compares to others brand.

  50. KYAW TUN says:

    After update IOS 9.01 fail to enable Application under cellular mode. Therefore please advice how to solve this kind of problem as soon as possible. I am no happy facing this kind of problem. urgently please assist for this problem . Thank you !

  51. Krissy says:

    I had this issue and I was able to fix it. First, backing up my contacts on lookout app then restoring my phone as new using iTunes. I restore my contacts by using lookout and not iCloud or iTunes as I was still having the same issue restoring from previous backup using those two. Nonetheless, I restore my phone as new using iTunes, download contacts from lookout backup before restore, and reinstalled previous apps. This seem to resolve the issue. It appears the upgrade is causing a freeze in restoring backup once you upgrade.

  52. Gary says:

    The following PC Magazine link which is only a bit more than 2 hours old, confirms the behavior I described above in my reply of September 28, 2015 at 5:29 pm:


  53. Gary says:

    Apologies if this has already been mentioned, but it appears that any apps for which cellular data was enabled at the time of the OS upgrade, still work and the cellular data “on” setting persists. However, if an app was disabled for cellular data at the time of the upgrade, the enabling of cellular data will not persist. On my iPhone 6plus, I had the Waze traffic app enabled for cellular data at the time of the upgrade; now it is the ONLY app for which the cellular data “on” setting persists.

  54. Rob says:

    This is a follow up to the post I made in 26 Sept.

    Cellular data for my apps had been working for last 2 days. This morning, the problem has returned. I called Apple Support and they asked me to “reset network settings” and then “reset all settings” – neither worked.

    The Support Tech then spoke to his supervisor who said Apple are aware of the problem and they are working on a fix that will be included in the next software release – there is no reset that will provide a permanent fix – only a software update will resolve this. He said they will get 9.0.2 pushed out as soon as possible. I hope so!

    • A little birdy says:

      Indeed, have heard several reports that iOS 9.0.2 will be released to address the cellular data issues that have come to iOS 9 and iOS 9.0.1. Some users report no cellular data works, while others report excessive cellular data usage with iOS 9, appears to happen to both iPhone and iPad users. This is what iOS 9.0.2 will address, apparently.

  55. Bleu says:

    I think they have forgotten to replace some lines which contains the word “cellular” in the new ios 9 software with “mobile” the word they started to use.

  56. Wattsfan says:

    What phone are you using?

  57. Wattsfan says:

    Does not exist on an Iphone6

  58. Wattsfan says:

    To Jeroen, that setting does not exist. Please advise.

  59. Jeroen says:

    Just a quick fix for people like me who updated to ios9 and where they lost Cellular data (I have T-Mobile and an unlocked phone).

    You just go to your SETTINGS > GENERAL > PROFILES and delete the Mobile Internet profile there. Restart your phone and your internet should be back

    • Joel says:

      Thanks man! that worked!

    • tmacauley says:

      FYI thank you!
      using ios 9.0.2 my t-mobile data had trouble if LTE is enabled before your fix. turning off LTE allowed reliable data service at 4g (california, unlocked iphone5)

    • Elizabeth says:

      Thank you! I have been trying for weeks to get this resolved. I updated to iOS 9.2 hoping that would do the trick, but still nothing. I was also going to do a total restore of my phone, but had the same problem as Maria mentioned above. This is the ONLY thing that has even remotely worked, and I’m finally back in the communication game.

    • Manuel says:

      Thanks a lot, that worked for me too!!!

    • Lee says:

      Thank you, it worked!

  60. Wattsfan says:

    In response to Lisa’s question if the phone is verizon. No, it is carrier independent. The problem is if you had cellular off in 8.4.1 it remains off in 9.0.1. I had maps off in 8.4.1 and it remains off in 9.0.1. I had the App Store off in 8.4.1 it remains off in 9.0.1.

  61. Lisa Snyder says:

    Just curious how many of you have Verizon Wireless?

  62. Enoxxox says:

    Helppp!! my iPhone is nothing without WiFi :((

  63. maria says:

    I’m trying to select an old back up from my computer and it’s not letting me. It says I need to turn off Find My iPhone on iCloud settings and I can’t because cellular data for my settings are off and won’t turn on, so I can’t turn off Find My iPhone and can’t restore my phone using an old back up. Is there any way to select a back up on your phone?

  64. maria says:

    I’m trying to select an old back up from my computer and it’s not letting me. It says I need to turn off Find My iPhone on iCloud settings and I can’t because cellular data for my settings are off and won’t turn on, so I can’t turn off Find My iPhone and can’t restore my phone using an old back up.

  65. Amy says:

    Rob- did that erase any personal data ?

  66. James Doll says:

    I have the iPhone 6s and followed the steps above to do the downgrade after trying everything else and it worked. It was iOS 9.1 and cellular data was working. When I got up this morning it was not working. I didn’t touch my phone at all so I’m confused. The fix described in #6 above works but it was temporary

  67. Rob says:

    After updating my 5S to OS9, my cellular data would not work for apps when away from a wifi network. I would switch cellular on for a particular app (at Setting>Cellular), leave the settings screen, and when I came back cellular data for that same app had mysteriously been switched off again.

    I called Apple Support and they said I had to “Erase All Content And Settings” at Settings>General>Reset. After that, I had to select a backup from one that had been done on a date BEFORE the OS9 update when it was running on OS8.4.1. If you use a backup that was done after the update then you’ll just bring back the same problem.

    Several hours later, I have functioning cellular data for my apps again :)

  68. chris says:

    After updating my 5s to OS9 my cellular data didn’t work. I took the phone to the AT&T store and had the simm card replaced. I can make calls now but most apps still don’t work(((

  69. David says:

    Impacted also with my 5S…i try all possible tweaks…no working…

    No more to add than that confirm again, Mac Users are FREE BETA TESTERS….it’s again a LAME update, like all what Apple do since 2/3 years….

    No need to touch or tweak your Device, wait for 9.02 as Apple say =

      The “ios_support” twitter account is not Apple and has nothing to do with Apple, they routinely tweet falsities. I wouldn’t trust anything they tweet, it’s less reliable than a rumors site with good reporters. Of course Apple is aware of the issues, they harvest huge data on crash reports, forums, the web, and their tech support lines.

    I had the exact same problem when I upgraded to iOS 9.0.1. I was the phone with my cellular carrier and Apple for an hour and everything they told me didn’t work whatsoever. They said that if the problem wasn’t resloved by Monday, they would send me a new phone. ‘New’ as in refurbished. I was going to wait but reading your comments made me lose faith. Sorry Apple, It’s androids turn!

    Thank YOU!
    Your tips helped more than you know.
    There are a couple of apps that I rely on for emergencies, and after the iOS 9 update, they stopped working without WiFi. I thought that the 9.01 update, would help, but it didn’t.
    Following your tips, everything works as it should again, and I am grateful for that…this could have meant the difference between life and death in my case.


    God Bless.

    I have been for iOS 9.0.1

    If i have cellular data disabled for a particular app and try to enable it, the setting does not hold. Once i leave the setting screen, it goes back to disabled. This is the case whether you go to the individual app’s settings or to Settings > Cellular > use Cellular Data For.

    Disabling cellular data usage for an app works fine, but you can’t turn it back on

    Why does Apple always make this so infuriating? It seems this problem always happen in the last few updates. Except this time for iOS 9.0, it just doesn’t seem to go away. I’ve tried everything except hard reset, if this doesn’t work I’m just taking it to Apple and complaining. I’ve tried calling Apple Support, and they are just so useless. Some try to help, and some are just so freaking dumb.

      Set button as soon as you leave the screen it unsets itself.

      My 5s is two years old a 6s is not in my future.

      My 2 years is up.

    I tried every step in trying to restore the cellular toggle for certain apps including resetting and downloading beta 9.1. Same damn problem. Interesting that the new News App retains the cellular setting but Flipboard does not. Although neither does Apple Store. When will they get this fixed???

  76. Wattsfan says:

    I did not downgrade to 8.4.1 and go that route. I tried everything else except erasing my phone and starting from scratch. This is a major bug. I have 9.0.1. iPhone 6. Same problem with 9.0. My apps that had cellular off in 8.4.1 remain off now. Unfortunately my maps were on off. So, no maps. Burned again as a beta user…

  77. James Doll says:

    I initially had the problem when installing iOS 9 to my iPhone 5s. Just bought the iPhone 6s today and same thing. What the hell apple!!!

  78. Dave says:

    I have been a beta tester for iOS 9.1 for a few months and can tell you that it has problems with enabling cellular data usage for apps.

    If you have cellular data disabled for a particular app and try to enable it, the setting does not hold. Once you leave the setting screen, it goes back to disabled. This is the case whether you go to the individual app’s settings or to Settings > Cellular > use Cellular Data For.

    Disabling cellular data usage for an app works fine, but you can’t turn it back on. The latest beta 2 upgrade for iOS 9.1 does not fix the issue.

    I have not experienced any other problems with iOS 9.1

    I’m unable to change Mobile data app settings.IOS 9.01

  81. Ari says:

    Had the wireless data signal drop down to EV-DO (which made me laugh) in an area I can almost always get 3-5 bars of LTE.

    I enabled and then disabled airplane mode and that did the trick for me. Haven’t seen it happen except that one time – but thought to post my experience with it.

    thank yoy.

  83. Ted says:

    I wish Apple would just stop this stupid, nonsense rat race of having a new update every damn year. Instead, they should focus their efforts on decent thorough testing before releasing their buggy systems. iOS 7 still works flawlessly on each of my devices. There’s no way I’m going to screw them up by upgrading. Good luck to all brain washed people who think they life won’t be a fulfilled one unless constantly upgrading to the “latest”.

  84. Squirrel says:

    iOS 9 is so problematic for some people, and trouble-free for others, what gives? Isn’t the point of the public beta program to test the releases are more real world situations and avoid these problems?

    Cellular data failure is a big problem on Apple iPhone Support discussion boards, and nobody has a clear answer except downgrading! At least Apple Support is aware of the problem(s) but that isn’t any less frustrating.


    What a headache. I guess I am glad the only problem I’ve had was a 3 hour install ordeal followed by the UI lag, which makes your iPhone 6 feel like an iPhone 3G with gunk on the screen.

    • INDC says:

      Honestly, I think the software glitches are somewhat deliberate on Apple’s part. Apple does this so people with older phones get frustrated (and thus will ideally upgrade to the latest phone). Those with the latest phones probably won’t experience these bugs. It’s a manipulative way of ensuring people continue to upgrade the hardware with the software. All tech companies do this to some extent…but with Apple this scenario is a little more obvious.

      • KDW says:

        Although I agree with your assessment for older phones, I already have the latest iPlus 6 and I still cannot connect via cellular data. My trust in Apple has been obliterated lately. Very frustrating.

        • KDW says:

          I also did a backup and restore. The problem? The bug is backed up as well. When I restore, the same problem occurs. My only choice has been to downgrade back to 10.8

        • INDC says:

          Yeah my trust in Apple has plummeted quite a bit, too. I’ve never used an Android phone but I’m willing to give it a shot at this point just to see if there’s less frustration (there’s probably less cost at least). Apple was great when they came right out of the gate with the first few generations of the iPhone, but now it feels like they’ve become just like the big lumbering ineffective tech companies they were once superior to.
