No cellular data after upgrade to ios 6.0.1

I upgraded to ios 6.0.1 on my iPad.
When I try to get email or open Safari I get a message "Could not activate cellular data network"
Any clues?

Do a backup and do a restore from backup.
If no joy, do a restore as new.

IPad 2 lost cellular service after upgrade to iOS 8.1

Device: iPad 2 Model A1397 16GB
My cellular service worked fine prior to the upgrade to iOS 8.1. After completing the upgrade, my cellular connection always says "Searching..." and never finds service. I have tried restoring iOS 8.1 through iTunes, but end up with the same results. I'm new to upgrading apple devices, so I didn't create a backup of my OS prior to upgrading. With Apple not signing iOS 7.1.2 anymore for my device, I'm in a bit of a pickle and cannot revert back. Any suggestions?

Make sure ringer is on and volume is up.

I cant make calls or receive and massage when off my cellular data after upgrading new version software

hi...
i have problems with my i phone 4s..
the problem is when i updated latest version that is 5.01(9A405),
i cant make outgoing calls,receive calls and massage something like being hang when i turn off my cellular data..
ive tried to soft reset and network reset and the result is still the same..
i hope u can help me solve my problem soon as possible..
tq..........

Try going to the recent apps by double clicking the home button, then touch and hold an app along the bottom of the screen until they all start to vibrate and a red circle with a minus sign appears on the corner of each. Tap each red circle to dismiss each app. Then do a reboot by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if that appears.
If that does not help you can contact Apple support at the appropriate locality number from http://support.apple.com/kb/HE57

Icloud mail does not work over cellular network after upgrade to IOS 8.1.3

Hi,
Since I did the update to IOS 8.1.3 on my iPhone 6 Plus yesterday, my icloud mails cannot be received/sent with my phone over the cellular network.
In order to make mails workin' I need to be connected to a Wifi network.
All setting are correct on the phone.
How can I fix this **** issue.
Deleted the icloud account already and added it again but that does not help.
Also when I try to connect to iCloud from the iCloud settings it says: Authentication Failed - A server error occurred.
The password is correct.
Please help me.
Jerry

I Fixed it by trying to sign in with a different ID and canceling when it asked For a password and then signed in with my ID and it works! No more error message. I got this idea from another discussion. Thank you for replying though.

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old.

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old. It;s been working perfectly up until now. I have no problem on my home WIFI, or through personal hotspot working through my iPhone 5.
I have worked with AT&T, replaced the SIM card with a new one, and done a backup/restore to factory settings, all with the same result that when I turn Cellular
Data on, with or without Enable LTE, it goes into "searching" mode, or reports "no service". My iPhone 5 works perfectly on iOS 8.1.2, on Cellular. I've browsed the blogs and have tried Apple's suggested fix, all to no result.
Oddly enough, every once in a while I do get connected to the network for a short ime (minutes), but it always returns to "searching".
I've filed a report with Apple, along with a request that they contact me, but no results yet.
Help? (and thank you).

Hello razmee209. Thank you for your response. I spent the better part of yesterday working with Apple Support. They tried their best, to include backing up photos to my HP laptop, backing up the iPad to iCloud, then resetting the iPad in total. Same problem. I restored from the cloud to recover my apps, same problem.
AT&T installed a new sim card - same problem. I spent time with AT&T Support yesterday, too. In both cases, (Apple and AT&T) the support techs who worked with me were extremely polite, courteous and helpful to the best of their abilities, but I think the problem lies deeper, and nobody at Apple is admitting they have a problem with iOS 8, that I'm aware of.
I didn't have this issue before I upgraded to iOS 8.1.2.
Everything else with the iPad works fine: WIFI, Personal Hotspot, email, all my apps, etc.
In browsing the web for this issue I see that many other folks have the same problem. I filed a report with Apple this morning, requesting that they contact me, but no word yet. I was going to go to iPhone 6, and had been considering the iPad Air 2, but I see reports of this problem with those units as well.
At this point I don't think I'll be spending any more money with Apple, at least not till this issue is resolved.
Thanks again for your response and suggestions.

Use iTunes to restore your iOS device to factory settings

After upgrading to iOS 8.1 my health data is missing!

I am a diabetic and I was using the health data for tracking my Blood sugar levels in iOS 8.0 . How ever after upgrading to iOS 8.1 all the previous recordings are gone!! Can somebody tell me why this is so?? I am using iPhone 5.

FIRST, back up the phone to iTunes, then sync it. A sync will frequently reduce the size of Other. If that fails, connect the phone to your computer, click on its name in iTunes, and click Restore iPhone. First time, restore your backup. If Other does not get smaller then you will have to restore again and set it up as New, then manually add back your apps and music. You will lose any app data, however. It may help to understand what Other actually is. See: What is "Other" and What Can I Do About It?

After upgrade to iOS 5 there is a large chunk of data ( 9Gb) on the phone labeled as "Other" in iTunes.

After upgrade to iOS 5 there is a large chunk of data (>9Gb) on the phone labeled as "Other" in iTunes. I suspect this is the music library from before the upgrade. How do I delete this data?

Same happened here on my iphone 4. I heard it's something about bad meta data in the music files but I've no idea. It seems to be fixed by deleting the music from the iphone and then syncing it back on. No need to reset so far luckily!

Problems with your internet connection after upgrading to iOS 7.1.2

After upgrading to iOS 7.1.2 on my iPad Retina display does not connect to the internet more. Recognizes the Wi-Fi network but can not connect to the internet. The same thing happened to my wife's iPhone 5s, while my had no problems ...

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at
http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
Wi-Fi or Bluetooth settings grayed out or dim

Apple team, my sincere request to you:Please attend this bug asap. It really dissolves the purpose of an iPhone..
Keeping my fingres crossed till then!
