  • 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.

  • Having just upgraded to Ios6 I can not log into my carrier. I get the message "Could not activate cellular data network. You are not subscribed to a cellular data network." What can I do to rectify this?

    Having just upgraded my iPad to IOS 6 I can no longer log onto my 3G Carrier. I get thi message "Could not activate cellular data network. You are not subscribed to a cellular data service" what can I do to rectify this?

    I reset APN settings from my carrier service site and rebooted but it didn't fix the problem.

  • HT4623 My new iPad can no longer connect to the 3G network. I keep getting the message "could not activate cellular date network".

    I updated my new iPad to the iOS 6 while connected to wifi. However, it will no longer connect to the 3G network. I keep getting the message "could not activate cellular data network" even though the 3G symbol appears normal. I have tried rebooting, but it still doesn't work. Please help!

    No. You can't

  • "Could not activate cellular data network" dialog, tried nearly everything, please help!

    I have had my iPad 3 since it came out. The 4G has had occasional issues, but I was always able to connect. Now out of the blue, after working perfectly well yesterday, it suddenly says "Could not activate cellular data network" when I try to go to the browser. The signal looks strong with Verizon LTE on top of the screen. I can also go through the Verizon dialog to see my account and how much data I have used so far, so in some way I am clearly connected to the cellular network. I have tried resetting the network settings, then re-provisioned, rebooted and still have the same problem in every detail. If anyone has any ideas on what else to try short of clearing the machine back to factory settings, please let me know.

    Verizon is having trouble. I'm trying to activate my phone and they said they were having trouble activating the SIM cards. They said they would call me back when they resolved the issue. It's been about 40 minutes now and I haven't heard from them and I can't do anything on my old phone because everything is tied up due to the pending order.

  • ERROR: Could not activate cellular data network: PDP authentication failure

    I have an iPhone 3g that was given to me by a friend a couple months ago. Before I got the phone i was on a plan with Softbank in japan with another cell phone. When i got the iphone i unlocked it so that i could use my old sim card with the iphone. everything worked out fine, i was unable to use the internet via 3g since it wasnt on my plan but i could text and make calls with no problem.
    Everything was working fine until yesterday when i started getting this error message: "Could not activate cellular data network: PDP authentication failure"
    once this happened i could no longer text or make calls. my iphone recognizes the sim card, shows one bar of signal, the network, and the 3g symbol. i have also rebooted, restored, reset network settings, and talked with Softbank; all had no help.
    i have no idea how to fix it, any suggestions would be awesome.
    thanks.

  • 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!!

  • "Could Not Activate Cellular Data Network" in Messages App

    I disabled my APN setting coz I don't want to use data network of my carrier for now.
    Why do I get the error "Could Not Activate Cellular Data Network" when I go to Messages? It doesn't use data connection or internet connection since its only SMS. The pop-up error message is irritating me. Makes me think that something in Messages App also eats data in the background for some reason.

    Try to switch Off mms service ...
    mms uses data !

  • "Could not activate cellular data network" message  on iPhone 3GS (iOS 4.1)

    May this year I purchased a brand new iPhone 3GS 16GB from Vodafone on a 24mnth plan with 2gb of data monthly for mobile and tether use. The 3G and normal gsm data alwyas worked in areas where it was avalible until 3 months ago. In safari i would get a message stating that "Could not activate cellular data network" and in all apps no internet serivces worked unless wifi was activated.
    I put my sim in my n95 and my 5800 and internet worked on both. I got my number put onto a new sim card. I restored iPhone. I updated iPhone to 4.1 and reset all network settings.
    Nothing worked and apple came to the conclusion that it was a faulty handset and replaced it on saturday. Today when I woke up, the same message appeared!!!!
    Please anyone help

    I am having similar problems.
    My network settings are correct and I can communicate both over 3G and WiFi.
    However, every few minutes the connection is being dropped. A few seconds later it's back again. I can see this in an application I am developing. It's rather frustrating...
    In the console I see this message prior to the connection being lost and rebuilt:
    "Mon Sep 20 09:44:58 PeterVs-iPhone-3GS configd[23] <Notice>: network configuration changed."
    I have not changed anything to the configuration. What's even more strange is that I ONLY have 3G at this moment, i.e. WiFi is disabled.
    What is changing the network configuration? And why does it mean that the current network connection needs to be torn down and rebuilt? After the network is back, there is no difference than before. So it gets torn down and rebuilt for no apparent reason.
    I have logged a bug with Apple over a week ago, but haven't had any reply from them yet. I need more information about what is happening, and how I can prevent it. I'm not very happy having to grope in the dark, having to make guesses because somebody decided that he knows what's best for me.
    This is happening on multiple iPhones with multiple different OS-es. So I am guessing it is related to my carrier (Vodafone). But I can't verify it because I'm not getting the tools from Apple.

  • 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.

  • HELP : Could not activate cellular data network ?

    Hello i have just updated to OS4 and when i try to access my mails i get the following message:
    "Could not activate cellular data network - you are not subscribed to a cellular data service."
    What is going on? iTunes gave me message that it could not 'activate' me now and that i would have to try again later. I have since then plugged in my iphone numerous times in iTunes. I don't get this 'can't activate now' message but I still cannot access my mails in my phone and i still get the message above.
    no mails = help plz!!!!!
    thxs,
    me

    sorry for delay in posting my reply. I have found that updating had in fact cleared all my cellular settings. basically it just needed to be reconfigured again. Why it cleared all the setting is a mystery.
    Also, as a 3G user, I am not entirely convinced the new update is that good on the 'old' 3G. I have suffered from loss of performance and stability. My phone regularly gets stuck. Apps shut down of their own accord etc...
    Am desperately waiting for the iPhone 4 to come out.

  • 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.

  • 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.
