Iphone 4 cannot use cellular data anymore after 4.2 update

I have an iPhone 4 and I have recently updated it to the latest o.s. after updating I can no longer use the internet without wifi and I cannot send/recieve picture messages (have tried to send and recieve with multiple carriers) and my phone sometimes does not recieve calls or regular txt messages. Please help.

It's weird, I'm having the same problem. Once I deactivate WiFi my iPhone 4 doesn't get 3G anymore, I have to reboot in order to get data back.
This is also after updating to 4.2.

Iphone 5 - "use cellular data for" option only shows Facetime and Passbook

I have an iphone 5 and I am trying to manage my cellular data usage,
When I go into Settings - Cellular and I look at the "use cellular data for" option, there are only 2 apps on the list Facetime and Passbook.
I have seen other posts online that show a long list of apps that you can toggle Cellular data on and off.
How can I see a longer list of apps.

In Settings/General/Restrictions if you tap on Cellular Data Use there should be 2 options: Allow Changes or Don't Allow Changes. If you don't see these options is that where you see "Cellular data is turned off for 'Setting'?
Do you have a corporate MS Exchange email account on your phone? If so your administrator may have added an override on this setting.

IPhone 4S - No Cellular Data Activity After Updating To iOS 8.0.2

My phone is unable to activate and/or use cellular data after updating to iOS 8. I have already installed 8.0.2 which promised to fix these issues; and it has not. Google Maps, Chrome, Safari, iMessage...none of these features work unless connected to WiFi. E-mail does not update and the phone is entirely useless without WiFi (even regular phone calls are sporadic). I am at a time in my life where having constant and reliable access to my e-mail, GPS, text messages and phone calls is vital to my daily life, as well as my future (new job application responses, current job responsibilities, etc.) Can anyone help with these issues? If not, Apple has surely lost a customer. Totally unacceptable.
Thanks in advance to anyone who can help!
Note- I had NONE of these issues prior to the dreadful update.

I'm a developer. I had this problem with my app for about a week until I found the culprit. For reasons the are not clear, my Ajax calls came back with an extra "0" on the return, which threw everything off for my app. This only happened on AT&T. It worked fine with all other providers. I found the solution in Stack and then implemented it. Fixed it for us.
Here is the problem & solution for other developers having the same problem.
The problem is apparently unique to AT&T, and is described below with a proposed solutuion.

Not sure if this is a result of AT&T throttling, or some other issue unique to them, but I just wanted to make sure other developers were aware of it because my team and I wasted a full week trying to relolve this.

My iphone 5 uses cellular data even when in WIFI mode. I have an iPhone 3 and 4s and both of those appear to be OK. How do I stop this?

My iPhone 5 on iOS 6 uses 4x to 5x the data that was being used on my iPhone 4s. The old 4s and 3g (differnt numbers) seem to be OK. AT&T is getting rich off of the cellular data when in WIFI mode. How do I stop this?

Hello there MyAppleHasAWorm,
I was researching what might be causing the excessive data usage on the iPhone 5 and found some info that should help reign in the data. It is from our iPhone Troubleshooting Assistant found here http://www.apple.com/support/iphone/assistant/phone/#section_1
Here is section 1 to get you started. I recommend sections 1, 3, and 5 if needed.
Restart iPhone
To restart iPhone, first turn iPhone off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPhone will turn off after a few moments.
Next, turn iPhone on by pressing and holding the Sleep/Wake button until the Apple logo appears.
Is iPhone not responding? To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.
If your device does not turn on or displays a red battery icon, try recharging next
All the best,
Sterling

Apps disappeared from "Use Cellular Data For" after iOS 8.0.2

Normally, when you go to Settings->Cellular Data, you can see a list of all apps that use data, and you are able to turn cellular data on or off for each app individually.
I had been using this feature since iOS 7 without problem, until I upgraded to iOS 8.0.2.
Now, only "FaceTime" and "Passbook" appear under this list. All other apps, including Mail, Safari, etc. have disappeared.
What's worse, apps for which I had turned cellular data for---such as YouTube---cannot be turned back on, because they have disappeared from this list. Therefore, I am permanently unable to use YouTube without Wifi because of this bug. The same goes for every app for which I had turned off cellular data.
I tried restoring the iPhone (it's an iPhone 5), to no avail.
Does anyone else have this issue, or is it a weird bug with just my phone?

Hi jah_mez69,
No, I did not solve this problem, and it persists in iOS 8.1.2.
Apple have a reluctance to take bugs affecting smaller groups of users seriously. With regard to this bug, their attitude is that we should just erase our phones and set them up from scratch. This is something I refuse to do.
I did open a new bug about this in the bug tracker (bug #18732898). It hasn't been closed yet, which means at the very least, they have not decided to totally ignore this bug forever. However, don't get your hopes up for a fix.
I have learned to live with it, but it has pushed me closer to choosing Android for my next phone. I am fairly confident that iOS software bugs are far less important to Apple than developing smart watches and payment systems and getting the next "hot" feature out the door.

How to download and install ios 8.3 on iphone by using cellular data

No 'Cellular Data Network' after iOS 5 Update

Hi, I'm hoping someone can help me as I'm very close to throwing my iPhone at a wall...
I have recently updated to the OS5 however there's no option to edit any APN's in the Network section of my settings. I am unable to use data unless connected to WiFi because of this. I have tried reseting the network settings, going into and coming out of airplane mode and also restoring my iPhone through iTunes... nothing's working! I know the option is available as my friend has a iPhone 4 with OS5 and the option is visible in their menu.

Solved it, I had to manually create a profile for the iPhone with the APN settings in and then install it.

IPhone 4, iOS7, cellular data control by app doesn't include all apps

Settings | Cellular | Use Cellular Data for: [app list]
The ability to control which apps cannot use cellular data is really helpful, but on my iPhone 4, certain apps aren't appearing in the list, for example, YouTube and Instagram. I need to figure out how to turn off the cellular data for the apps missing from the list.
I did compare this to another iPhone 4, and an iPhone5 - the other 4 had the issue, but on the 5, all the apps were listed.

i'm guessing you used more than one iTunes store account to purchase content.
if that's the case, try authorizing your Mac to play/use the content purchased from the other iTS account(s).
that's basically very easy. all you have to do is +log out+ of one account (click on the account name in the Store window and select +sign out+ from the pop-up dialog) and into the other, and then they will both be authorized. when done, sign back into your usual account. you'll have to do that one time only.

Thanks - but no luck there either. I believe they're referring to "Notification Center".

After enabling cellular data, i am receiving mails even if disable "use cellular data for mail", due to this data usage usage use is more, if we have fix please let me know

Phone Model and OS
Model - iphone 5
IOS 8.0.2
Problem Description
After enabling cellular data, i am receiving mails even if we disable "use cellular data for mail", due to this data usage usage use is more, if we have fix please let me know.
Steps:
1. Enable Cellular Data
2. Disable mail on "use cellular data for mail
3. check whether mail is received or not
tried multiple times and i am getting more billing amount because of data usage

Mail isn't the only app using data. Turning it off there has no effect whatsoever on whether the rest of iOS or other apps you have installed. In fact most apps use data these days, at a minimum for Notifications and often for gameplay and other features.

Why does my iPhone 5 lose signal when trying to make a call or use cellular data?

Hello,
I've had this problem for a few weeks now and it's becoming really annoying. Every time I try to make a call, or call voicemail, it takes me 10 or so attempts to connect. When it doesn't connect I get 'searching' in the top left hand corner whilst my phone try's to find signal again. I have the same problem when using 3G - it'll be fine for a while and then I lose my signal all together. This happens in places where I have enjoyed full signal strength in the past. I have dropped my phone or done anything to it to cause this. I've checked with my network provider, Giffgaff but it seems to be more of a phone problem rather than network.
Has anyone had anything similar? If so how did you fix it? I'm thinking I need to take it into my local store to get it looked it.

I have an iPhone 4s, and I reset the content and setting. It turned on, I chose English, Australia, and now, I am unable to connect/activate my iPhone through Wi-Fi, and for an unknown reason, it will not allow me to use cellular data or iTunes.

In order to download to your phone over the air, you need to be connected to WiFi.
It's possible the Internet connection through Verizon is not stable enough for the downlaod to begin (it is a very large download).
You might want to head over to Starbucks with your laptop for the afternoon and see if you can download it over their WiFi.
