Not subscribed to data network (UK)
For some reason at varied intervals I get a message popping up on my iPhone 3GS screen telling me that I am not subscribed to a data network. I am with o2 in the UK. I have signal and am able to make calls and text messages but cannot understand why this message keeps popping up.
Any ideas?
I would have thought that a phone call to O2 would be your quickest and most reliable way of resolving your problem!

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 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.

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. -
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..

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,
mesorry 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. -
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

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.

What does this have to do with using an iPhone in an enterprise environment?

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.
