This has probably been asked elsewhere so sorry in advance if it has!! Since leaving the house this morning (I use wifi at home) I've had "no network connection" even though I have full 3G signal! I've tried the hard reset & reset from the settings, I've turned my

mobile data off & back on again but nothing's changed, checked with my network provider (EE) who said its not my network and

to go to the apple store which I have but they can't see me until tomorrow. I have seen other people post about this on here but in there case the hard reset seems

to have resolved it but this isn't working for me! It's also coming up with the pdp connection error message when using safari.


Thank you in advance! Nikki.

    Hi Fordyy88,


    I'm sorry you are having issues connecting to the internet through your 3G network.

    It appears from the error message that the issue is with your Carrier. See below:

    When activating 3G service on an iOS device using a custom Access Point Name (APN), the error message "Could not activate cellular data network: PDP authentication failure" may appear.

      • 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, o rcontact AppleCare to troubleshoot further.


    I hope you are back on track soon!

    Hi judy.


    Thank you very much for your help! It turned out that it was my network that was having the issue & there Internet coverage was down across the uk! They just didn't let anyone know until later in the day!


    Thanks again for your help :) Nikki
