IOS 4.3 could not activate cellular data network
I just updated my iPhone 4 to iOS 4.3 and now I cannot connect to the cell network.
I have never done a jailbreak on my phone. I'm on Rogers and my blackberry is working fine so it's not a network outage.
I have done the following to try and fix this:
1. Toggle airplane mode
2. Soft reset
3. hard reset
4. reset network settings
This started happening as soon as it was done rebooting after updating to 4.3. What else can I do here? The only option I see now is to do a full wipe but if anyone else has any ideas please let me know.
Hi
Try this then:
"If you're a Pay Monthly customer but don't have the iPhone Bolt On, or a specific iPhone tariff, then you won't be able to get the full iPhone experience.
Here's what you'll need to do:
From the main screen of your iPhone tap Settings > General > Network
Under Cellular Data Network
For Pay & Go customers. Tap APN and change idata.o2.co.uk and enter payandgo.o2.co.uk (Please note that "o2" needs to be written with a letter "o" and not a zero)
For Pay Monthly customers. Tap APN and change idata.o2.co.uk and enter mobile.o2.co.uk (Please note that "o2" needs to be written with a letter "o" and not a zero)
You don't need to change your username and password
Ignore the Visual Voicemail APN box - it's not available to Pay & Go customers or Pay Monthly customers (with a non iPhone tariff)
Under MMS
For Pay & Go customers. Tap APN and change idata.o2.co.uk and enter payandgo.o2.co.uk (Please note that o2 needs to be written with a letter o and not a zero)
For Pay Monthly customers. Tap APN and change idata.o2.co.uk and enter wap.o2.co.uk (Please note that o2 needs to be written with a letter o and not a zero)
You don't need to change your username and password
Turn your iPhone off and on again
If you're a Pay & Go iPhone customer, using your iPhone sim for the first time, you'll need to top up by at least £10.
For a step-by-step walk-through on how to change your settings, have a look at our interactive guide."
So that's the text from the link I posted.
I'm sure there's an analogous process for other networks. Perhaps it doesn't affect US iPhones as there was only one network to cater for up until recently..

I now get this message since updating to iOS 5.01 - it won't work on my 3G anymore - anyone else have same issue and/or know how to fix it?!!!!
I changed my DNS settins so they point to OpenDNS DNS servers
On a Mac go to SYSTEM PREFERENCES>NETWORK>ADVACED>DNS
change DNS by adding ( + )
208.67.222.222
then
208.67.220.220
click okay/apply after. then try the update. after the update, just delete the two open DNS server numbers. should revert back to your old one. -
"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
Message was edited by: r.spiroskiI 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. -
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

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.

"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.
Thanks for reaching out to Apple Support Communities.

Could not activate cellular data network fix
Im on an iPhone 5 with iOS 6.1.2 with StraightTalk and any time I attempt to connect to the internet with 3G it say "Could not activate cellular data network. You Are Not Subscibed." I need a fix for it! Please help!
This is not an uncommon problem apparently.
Did you try dialing *22890?
How did you activate your iPhone (iTunes, iCloud, WalMart kiosk)?
Some on the StraightTalk forums report success by visiting a WalMart which is equipped with an activation kiosk and asking a qualified WalMart empolyee to activate the phone (be sure and back up any critical data before you do that since they will reset the phone).
Also, are you in the home area code of your phone? My iPhone 5 was set to not allow data roaming outside of my home network. I am not sure if that means my area code or the StraightTalk network. Either way, you can go to Settings>Cellular>Roaming and check to see if data roaming is turned on. Be careful if you roam a lot, though as you might incur additional data charges.
Hope this helps. -
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.
-
Could not activate cellular data network. You are not subscribed to a cellular data service"
"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. -
Ipad 2 "Could not activate cellular data network" message
Ipad 2 "Could not activate cellular data network" message after I updated to iOS5 despite the 3G network being displayed on the menu bar. How do I resolve this, folks?
There have been some threads with similar problems. One I recall was a user not being able to sign up for cellular service from Verizon after an update to ios 5. The problem seemed to be on verizon's end. If Verizon is your carrier call Verison to find out when they will have a fox for this problem.

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 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 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.
