If you have a data only plan for the iPad with your carrier, if no change after powering your iPad off and on you will need to contact your carrier.

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.

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.

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

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 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.

Hi. After I updated ios6, I couldn't use my cellular network. It said "could not activate cellular data network - You are not subscribed to a cellular data service". I don't know why. My iphone is 4s
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.

i cannot connect to the net using 3G, i have ipad2 16GB, i have tried resetting my ipad2, and resetting the network setting, my location is here in riyadh, everitime i try to connect to the net theres a pop message saying "could not activate cellular data network, please help me guys thanks.....
Thanks for the quick response. No, I did not get any error messages or any terms-of-usage screen. The employee I told my problem to was not computer savvy either. She just suggested I move to different spots w/in the library to see if that would make a difference. It didn't. When I connected to the library WiFi it did change the Verizon 3G that is usually in the upper left corner to iPad with two to three emanating arcs. I may have to go to the library in the next town. I was able to connect to theirs in the past when I had to download something greater than 20 MB. Unless I really want it, I will probably not even try to download something more than 20 MB due to the hassle. Yeah, I may have been better off getting a normal desktop or laptop and getting WiFi at home. To do that now would mean having my iPad 2 and a desktop computer, which I feel is extravagant. (I know there are a lot of big spenders out there who got the iPad as additional gadget for fun. This is a rich country.) A Verizon rep told me I couldn't set up a WiFi router at home just using an iPad. So it seems like a person who just uses 3G is limited to surfing the net (not even much YouTube because it eats a lot of data) and using email. I read about an app that helps print wirelessly using 3G, but a reviewer said you had to be an engineer to get it done right. BTW, I like the Steelers. I'm old enough to remember Franco Harris and that blond guy whose name escapes me back in the '70s. Since I live in North Jersey I feel I have to support the Giants. But I know football about as well as computers.

Hi all,
I have recently acquired an iPhone 3G 16GB. It is unlocked and I have put my sim card in (Virgin Mobile) and used it without problem when calling or sending text messages. The internet all works fine when connected to a wi-fi network.
In the top left hand corner it says '3G', however if I try anything related to the internet (Safari, Twitter etc.) a message will appear reading 'Could not activate mobile data network'. This is very inconvenient for me. All internet related activities work fine when connected to a wi-fi network.
Is this a problem with all unlocked phones? Is there a solution to this? Or am I simply unable to use the internet without wi-fi on this model?
Any help would be greatly appreciated, all questions may sound silly, but this is my first iPhone and I am very inexperienced with them!
ThanksFirst, you don't have a 3G if you have iOS 6.1.4. The 3G cannot go higher than iOS 4.2.1. That is not related to your problem, but worth knowing.
Let's try the obvious first. Tap the Settings icon. Then tap General. Then Cellular. Is Cellular Data on? Is there an entry for APN? If there is contact your carrier and ask what the APN settings should be. If there is no entry don't worry; the APN is automatic with your carrier. -

my iphone4 says its cinnected to 3g but when i use safari it says "could not activate mobile data network". Any ideas please?
Further, if you are not in your home cellular carrier's area, you need to set Settings > General > Cellular > Data Roaming = "On".
