Yeah, I'm having the exact same problem. I think this quite ridiculous that this is happening out of the blue. There's another thread on this saying that Verizon cannot help our problem and the only thing they can do is send us another phone. Possibly we might have a faulty product. I'm going try and call them when I get home and see what they can do. I will be very disappointed if they cannot do anything and will have to send me a new phone. I don't want to have to wait for it to get mailed to me because I need my phone for work and school purposes. Anyways, I hope they'll be able to help you out. Best advice is to just call tech support.
If you are near an Apple store you will be able to get a replacement on the spot if they determine that a replacement is needed. Not sure if the VZW stores will do the same. Sorry some of you are having issues but hopefully it will be something that can be fixed soon.

I've Lost cellular data network and emails after 5.0 upgrade. "Could not activate cellular data network". Have turned off and on, removed sim and also checked APN setting can anyone help...

I've lost cellular date network, all unopened important business emails and internet access on my Ipad 2 after 5.0 upgrade. Received "Could not activate cellular date network" - I have turned on and off, removed the sim and checked the APN is correct. Can anyone help - struggling and need for my business.

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.

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?

Could not activate cellular data network error

i bought ipad 2 few days back. while i'm trying to connect to 3G i'm getting the pop up saying "could not activate cellular data network".. can anyone help?

If you have the sim version (AT&T in the US), did you purchase a sim card from your carrier, insert it and buy data? If you have CDMA version (Verizon in the US), have you contacted your carrier to set up a data plan?

"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.

Could not activate cellular data network message

I am on Vodafone UK and mostly have my phone on 2G mode. I get good EDGE coverage 5 bars but I am intermittently getting "Could not activate cellular data network" message. The settings are correct, as it sometimes works, 3G data is fine over the same APN. A Blackberry connected via EDGE seems to work fine.
Vodafone insist its not an issue with the Network, as I work for a contractor with them I also had the radio side of things checked and all seems ok. Now it could be a core network issue, SGSN or similar, or its bug in the iPhone firmware. I never had this issue prior to iOS4.
Anyone else, specifically having any problems with EDGE/GPRS? I would be interested to know.

I had this problem at 1st with t-mobile 3g
connect it to itunes and it will say carrier update click accept on itunes that sorted it for me

Could not activate cellular data network on iphone 6 plus

I was using an att's prepaid gophone and just bought an iphone 6 plus yesterday. but it shows that "could not activate cellular data network" even if "at&t 4g" logo shows on the top of the screen.
I've asked att for help and they said that my sim card and account are totally correct. When I put other's SIM card in my iphone and put my SIM card in an 5s, both of two iphone worked well. but when my sim card in my iphone, the cellular wouldn't work.
att said that iphone 6 plus which is a very new device may not support prepaid card yet, but i'm not sure if it is the point.
did anyone meet the same problem? i've tried the old solution about clear the cookie and data but it didn't work.
hope for your helps

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" multiple times a day

Several times a day (up to 10 times/day) my phone says "Could not activate cellular data network" and this problem has been going on for about 2 weeks. Does anyone know how to help or troubleshoot it?

I was having the same problem with my factory unlocked phone. Try this it worked for me:
In Settings go to GENERAL-->NETWORK--> and turn off ENABLE 3G. I did this a week ago and I have not had an issue with dropped data since. Why does this work? I don't know.
BE AWARE THAT THE NEW 5.1.1 OS BY DEFAULT TURNS ON 3G EVERYTIME YOU RESTART YOUR PHONE, EVEN IF YOU TURN IT OFF MANUALY

"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" message after ISO 4.1 update

I updated my iPhone yesterday just like millions of other people, but since the update was completed, I haven't been able to use the data network. Wi-Fi works without any problems, but when I've been out of the house yesterday and today, I haven't been able to establish any connection to the data network and have received the "Could not activate cellular data network" message each time. Is anyone else having this issue too? So much for a flawless update.

Hi,
This happens to me everytime I do a f/w update but for me its for a simple reason and is easy to fix.
I am using a non iPhone Contract SIM in my iPhone and as such is does not like the default iPhone contract APNs for cellular data, hence the message. These reset when you do a f/w upgrade.
I have to go into Settings/General/Network/Cellular Data Network and set the APNs (for data and MMS) to ones given to me by my provider, in this case O2 UK for a non iPhone SIM/Contract - all is then well.
Perhaps you are in a similar situation ?? It shuold be easy to resolve by checking the APNs for your SIM against the ones in the iPhone itself. I found mine by Googling for iPhone O2 APNs. In fact in the end O2 published the setup on their website.
Hope this helps.

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

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.

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.

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.
