    "Cellular Data Plan Usage…There is no data remaining on your current plan. Would you like to add more data now?"what im going to do whit this problem??

    I have done that and it is definitely on.  My husband has the exact same phone and I upgraded his IOS at the same time, but this problem is not happening to his phone (we are also on the same plan, so our service should be the same).  Our settings appear to be identical and my phone is showing the 3G symbol at the top, so I can't understand why it won't access the network.
    I've turned it on and off twice and have reset all settings with my iTunes account, but it still isn't working.
    I'm not a complete idiot with this sort of stuff - I have tried all the obvious things.

    Contact your carrier to ensure data access via their network is provisioned properly for your account and iPhone with the new iOS 6 update installed.

  • How to solve the error message "Could not activate cellular data network: PDP authentication failure"when using 3g or gPRS on safari with an iphone 4 and latest software updates

    Please can someone help me to solve the error message "Could not activate cellular data network: PDP authentication failure"when using 3G or GPRS on safari with an iphone 4GS and latest software updates. I have tried resetting the network and phone settings. I have restored the factory settings on itunes and still the problem persists.

    All iPhones sold in Japan are sold carrier locked and cannot be officially unlocked by the carrier. If you unlocked it, it was by unauthorized means (hacked), and support cannot be given to you in this forum.
    Hacked iPhones are subject to countermeasures by Apple, particularly when updating the firmware. It is likely permanently re-locked or permanently disabled.

  • IPHONE 5: can't receive calls & random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network."  This occurs even when signal strength or wifi is operational.

    IPHONE 5:  can't receive calls and random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network."  This occurs even when signal strength or wifi is operational, and it does not matter whether wifi is on or off.  ATT went through the standard protocol - resetting network, resetting sim card, etc.  No changes.  Other phones working fine in same region with same carrier.  Apple's solution is to restore software, but haven't gone there yet.  Anyone successfully addressed this/these issues?   

    I should point out that it worked when the iPhone was set back to factory settings, but when restored with the backup, data/internet no longer works again, and I get the "Could not activate cellular data network" error message yet again.

  • Could not activate cellulare data network??? what is the solution please.

    everytime i try to log to the internet through the internet service provider on the phone, i get this message   (could not activate cellulare data network)
    I was loginig before via wifi meanwhile i do not have wifi and i am forced to use the service provider internet.
    What should I do , I tried the soft, hard reset as well as the restart with no sucsses.
    any advice???

    I had the same issue "Cannot Activate Cellular Data Network" sometimes says "No Internet..or You are not subscribed to a Data Network". The phone works fine on WiFi. 
    I noticed this issue only yesterday when tried to access my emails via 3G Data, this may have started happening when I recently updated to 4.3.2 and my phone has never been Jailbroken.
    I found a fix that worked for me..I'm using T-Mobile Germany.
    Go to Settings>General>Reset>Reset Network Settings>enter Pin code if you have lock enabled>choose Reset Network Settings..
    Remember doing this may also erase known WiFi networks, so you may have to enter the details again to get connected to a known WiFi network.
    My 3G data started to work again after I did the above steps to default factory network settings.
    T-Mobile Germany wasn't much help at all. All they could tell me was some crap about my config was in the wrong contract, Duh??
    They probably did nothing to fix the issue and I suspect the above resets steps resolved it for me. Give it a try..
    Cheers!!

  • I am getting an error message "could not activate cellular data network" with my iPhone when there is no wifi

    I am getting an error message with my iPhone whenever I try to access my data with no wifi.  It says "could not activate cellular data network".  This just started today and has never happened before.  Did I change a setting or something?

    Hello, romac12. 
    Thank you for visiting Apple Support Communities. 
    I have experienced this issue before.  If there have been any changes to your cellular account such as adding a line, plan change or upgrade, more than likely there is a provisioning issue on the carrier end.  However, I would recommend going through the troubleshooting steps in the article below.  If the issue persists, see step 9.

  • I purchased an unlocked iPhone4 last month. Everything was fine till yesterday. Today morning when I tried to check mail, i suddenly got an error message saying " Could not activate cellular data network: you are not subscribed to a cellular data service"

    I purchased an unlocked iPhone4 last month. Everything was fine till yesterday. Today morning when I tried to check mail, i suddenly got an error message saying " Could not activate cellular data network: you are not subscribed to a cellular data service", when I checked on my network settings i was not able to find the cellular data network tab ( where we use to input APN manually). i even tried to restore my iPhone to its factory settings, Still it remains the same. i cant able to connect to Internet using cellular data. help me...Plz..

    Where did you purchase it from?  There are lots of iPhones sold as "unlocked" which are carrier locked phones that were hacked and are not officially unlocked.  These phones are subject to re-locking to the original carrier, particularly when updated.

    Apparently, no one pays it... That's why they shut off your service.

  • Could not activate cellular data network on iphone 3g

    my phone's screen broke yesterday so i bought an iphone 3g from a frend of mine, its running on 4.0.1, i am already on at&t an have an existing data plan but when i try to use the internet i keep gettng this message "could not activate cellular data network" what do i need to do to fix this?

    I am absolutely getting LTE.  From the iPhone 5S on, the GSM and CDMA phones had identical GSM radios ostensibly for overseas use (in the case of the Verizon phones).  Verizon tells you they're only unlocked for overseas so that you won't leave their service for a domestic GSM.  Actually, all of the 6's have identical receivers, however the CDMA antennae are disabled on the T-Mobile and AT&T versions... which doesn't matter anyway because Verizon and Sprint won't activate devices that did not originate on their networks though theoretically you could run on Verizon LTE with a GSM only phone as GSM is required for LTE (thus the SIM card in later model Verizon phones).
    The Verizon model is the best of everything because it is completely unlocked for any carrier (except Sprint, but who cares, right?).
    Edit:  forgot to mention... Verizon is required to make all of their LTE phones GSM-unlocked as per their agreement with the FCC when they were acquiring LTE technology.

  • "could not activate cellular data network"

    got a new iphone 6 and repeatedly having problems using cellular data after bringing the phone out of sleep, if I turn it off and back on again it seems to work fine but will have the same issue next time "could not activate cellular data network" Anyone else experiencing same problem or have suggestions ?

    Hello there, Krasea.
    The following Knowledge Base article offers up some great recommendations for troubleshooting issues with cellular data connections with your iOS device:
    iPhone: Troubleshooting a cellular data connection
    http://support.apple.com/kb/ts3780
    Follow these steps for help troubleshooting cellular data issues on your iPhone. After performing each step, please test to see if the issue is resolved.
    Toggle airplane mode: Tap Settings, turn airplane mode on, wait three seconds, and then turn off again.
    Restart your iPhone.
    Make sure that your software is up to date:
    Check for a Carrier Settings Update: Tap Settings > General > About.
    Check for an iOS Software Update: Tap Settings > General > Software Update. 
    Note: Some updates may require a Wi-Fi connection.
    Remove the SIM Card and reinsert it. Allow the iPhone to acquire the network again.
    If your SIM card has SIM PIN enabled, try turning it off: Tap Settings > Phone > SIM PIN.
    Try another location. If a different location works, but the original location still doesn't, contact your carrier to report the issue.
    Reset network settings: Tap Settings > General > Reset > Reset Network Settings.
    Restore the iPhone as new.
    Contact your carrier to:
    Verify that the iPhone is properly set up on the account with the appropriate, current data plan.
    Verify that there are no account-related blocks.
    Find out if there are specific error messages in the carrier logs that could help determine why the issue is occurring.
    If none of the above steps resolves the issue, contact your carrier, make an appointment at an Apple Retail Store, or contact AppleCare to troubleshoot further.

  • Could not activate cellular data network on Verizon

    I have an iPhone 4 on the verizon network. Whenever I try to get online or check my email's or anything when I don't have wifi it says Could not activate cellular data network. I have called Verizon and they kept me on the phone for 2 hours and had no solution. I have reset the phone/network and have restored it and nothing has changed. Any help would be greatly appreciated!!

    I'm having the same problems.  No luck with network resets, *228/2, data roaming etc.  Good Verizon signal but no connection to 3g.  I called Verizon and they suggested replacing the phone.  The tech said he had seen a few iphone 4S with this problems so far.  Now I don't know whether to replace it through Apple or Verizon since I was able to add Applecare+ to this phone.
