Upgrade iOS6 to Iphone4 and cant activate cellular data network
I have recently upgrade latest os to my iphone 4 & followings are problems im having now with my phone:
1. Map is not working
2. Cellular data network not working
3. Wifi is weak & cant get signal strength like previous os
Appreciate if anyone can suggest what else needs to be check to sort it out or is there any way to move back to previous OS without any data loss?
Regards,
Jishu
First, I hope you did the standard reset of your iPhone. If that doesn't help, then you'll have to contact AT&T. This situation sometimes happens with AT&T. Get to tech support and they can determine if whatever routing that goes on with a cellular network is working for you. BTW, call from a land line, because you'll have to shut off your iPhone and restart. I hope this helps.

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.

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.

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.

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.

Hello im deployed in Afghanistan. I brought over my 64gb ipadw att over here. I got a new sim for it day one. It's work flawlessly for 2 months. Last night I upgraded from 5.1.1. to 6.1 and when it woke back up BOOM! I have all the bars along w/ the "E" Edge network icon but no internet. Says could not activate cellular data network. When I put my att sim card in my ipad works perfectly fine racking up ridiculous out of the country roaming fees. Why did my hodgi sim card stop working?
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. -
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 have problem c connecting to cellular data network. There is massage "couldn't activate cellular data network, PDP authentication failure". What is it and how I solve this problem?
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.

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

"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.

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. -
