Definitely sounds like an issue with your Wi-Fi network. Do any other devices on the network have similar issues? Is it an issue only with downloading apps? You can check by trying to load a website in Safari.
I would try turning your Wi-Fi router off for 1 minute, and back on again.
After doing that, disconnect and re-join the Wi-Fi network on your iPhone and try downloading an app again.

HELP I keep getting an error message on my IPHONE 4 that says Unable to connect to Cellular Data. How do I fix this?

HELP I keep getting an error message on my IPHONE 4 that says Unable to connect to Cellular Data and I have tried to reset network settings and factory reset but nothing helping so far. Took it to Verizon and they couldn't fix it either, said it's a problem with the phone itself and to contact Apple. My warranty is expired so Apple isn't much help either. How do I fix this? I have a data package so confused and I have had my phone for over a year but never had this issue before.

I am getting this message also.... mine cant update too...

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.

Why do i have to restart my iphone 4 to connect to cellular data network after moving out of wifi range?

Whenever I move out of a wifi zone, I expect my iphone to connect to cellular data automatically. But this doesn't happen. I have tried turning flight mode on/off and also tried turning cellular data on / off couple of times, but nothing works.
I only get the cellular data connection back after I restart my iphone.
I started having this problem after upgrading to iOS7.
Any idea how to fix this?

Hi beingkejo,
Thanks for visiting Apple Support Communities.
Toggling Airplane mode and cellular data are good troubleshooting steps. If your iPhone still does not connect to cellular data automatically when Wi-Fi disconnects, I recommend the additional steps in this article:

Can't connect to cellular data on my iphone 4s

So here's a description of the issues I've been having over the last several months. I cannot connect to or use my cellular data when not connected to wifi. Example: I will be out at the store or on my way to work and I will try to search google but I will get a page that says "unable to connect. Please check internet connection". Take in mind that at the top of my screen I will have 2-4 bars with 4G when this appears. I have also tried safari with the same results. I usually have no issues connecting to wifi but I can almost never use my cellular data because it says it can't connect. I have checked all settings on my phone. I have truobleshooted all and everything possible with my service provider and also with Apple and no one can seem to figure out why I'm having this issue. I have even restored my phone twice with no resolution. Note: this issue did not begin until after the 7.0.4 update, since then my phone has been a complete nightmare. I do have the current software updated and always do so that's not the issue either. I'm convinced that this has something to do with the software update from 7.0.4 because that's when all this crap began. Also, if I am talking on my phone and it's plugged in it shocks me. I have noted this issue with Apple also and they have done nothing. My phone is no longer under warranty, actually November was when my year warranty expired. The only thing they have said is that it is possibly a hardware issue and recommended I replace my phone, which I will have to pay $199.00 out of my pocket to do. I'm really irritated about this. I'm also convinced that the issue may very well be a hardware problem (according to Apple) but this hardware problem is due to their software that damaged it. I feel like they should replace it for free. I've noticed that anytime anyone has an issue apple can't fix they immediately blame it on the hardware then make you buy a new phone. Any advice on what else might be causing these issues?

Anyone?

Having a problem with iPad mini connecting to cellular service. Anybody else?

Hey there nemesyssoft!
Congrats on the new iPad! It's a great device! We certainly want you to be able to use the device as soon as possible. If I may ask, were you still having issues connecting to the data network at all? Activation can take be a bit longer the initial time. Please let us know if you still need assistance.
Thanks!

TS4006 can this find my iPhone app work if you are not connected to cellular data network and wifi

can this app work without cellular data network and wifi, if yes then how exactly this work ?

To use Find my iPhone you have to set it up on your iOS device before you lose it. Your device also needs to have iOS 5, be switched on and connected to wi-fi/3G.

IPhone 5 stays connected to cellular data while cellular data disabled in settings.

I am traveling to Europe from Canada and I have a huge issue with my phone not recognizing that it's cellular data is set to off. tried shutting it off and resetting it but notihng works. It just stays connected to cellular network, I keep receiving messages (whch I am pretty sure I am paying for each time I receive one). My understanding, and previus experience, made me believe this was a simple on and off thing, and that the phone would then use only wifi signal.
Please help, I have no idea how to be able to keep my phone useful when I am in wifi hotspots with out getting a huge bill.

They're the regular green and gray (even while messaging contacts I use Messages with and I'm connected to wifi).
Sorry, I think I explained it wrong in my title. I just mean, I am still connected to the cellular network and my phone is somehow ignoring being connected to wifi. It's showing full network bar and which provider I am connected to. I thought this would be diabled when I'm in cellular off. I just don't remember it being that way when I turned it off on my previous phone.

TS1398 iOS 6, cannot connect to Cellular Data

I have updated to iOS 6 last week, and since then, cannot get any signal from Cellular Data. It's really so inconvenient, apple, would you please fix this problem ASAP...?

IPhone 5c won't connect to cellular data after leaving wi-fi

Every time i leave my house's wifi for some reason my i phone 5c wont connect to celluar data? is this happaning to anyone els? please help and i just got my phone 4 days ago 2/24/14 Carrier Sprint.

Okay, if it is displaying 1X in the corner, then you are connecting to their slow internet. You need to contact Sprint and have them check your account. It almost looks like you are not provisioned correctly for data. Also, what is the signal strength on the phone when you are seeing this?
You can try a couple of troubleshooting steps before contacting Sprint. First, power the phone off. Hold the sleep/wake button down until you can see the red slider, then slide that until the phone powers off. Turn the phone back on and after it boots up, see if that corrects your problem. If not, then try a reset. This will not affect any data on your phone. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. The phone will reboot. This can take 15-30 seconds.

IPhone will not send MMS/ connect to cellular data

This may help some folk. I've just bought a 5s and after installing the new nano sim, neither the cellular data or MMS would work. Turns out that my carrier detected it was an iPhone, so when sending over the carrier settings, assumed I had a dedicated iPhone data plan which I haven't. All I had to do was change the cellular data and MMS APN details and it worked. Anyone with this issue should contact their carrier for the correct APN details. In my case I had to swap from idata.o2.co.uk to mobile.o2.co.uk.
Hope this helps!

Usually this is a carrier issue. Call your carrier and let them know. If its Verizon or sprint have them re-provision the account.

Firefox 3.6.15 on my Motorola Atrix Desktop system will not connect to cellular data connection.

I know the data connection is available because the phone browser works. Are there any settings I need to change? It's on the Orange UK network. They have failed to help me (their suggestions don't work)
It seem the browser can't 'see' the cellular network.

Have you tried the Easy Link Advisor application that Lynksys offers (free). It help me set up my network and it's very "User Friendly". It checks all of your router settings and then will walk you through the process to connect your PC's to the network. It's a large file, but worth it (for me anyhow) to download, install, and set up my network. Good luck!

Ipad mini won't connect to cellular data - fully

Got ipad mini for Xmas. Finally got round to getting EE SIM. Shows as being active with signal, but cannot connect to internet. Took SIM back to Carphone Warehouse (where SIM came from) and they thought it was the APN settings but checked and it wasn't. They then put the Sim into a phone and it worked fine.
They suggested that the ipad was blocked which happens when it's been stolen. It hasn't. I have my husbands receipt.
Have subsequently tried everything listed in these discussion pages and on Apple help pages including reset, on and off etc but it still isn't working. Have rung John Lewis (where ipad was purchased) and they have said to take it in to them. Thought I'd try here first as they indicated that it may have to be sent away.
Have ipad 2 with EE SIM working fine, but too much demand in our house for ipad to be without my new one!
Please help.

Thanks. Have tried switching to 3G already. Think I have turned on and off just about everything I can.
Have also tried to get cellular to work in a number of different areas (not just at home) including the shop where they got SIM to work in a HTc phone. I don't have an adapter but since the SIM worked ok in another appliance, I'm assuming that it's not worth me trying that?
When you put the SIM in, it's meant to automatically go to registration page for EE. I don't recall it doing that which is odd but it does come up as 'EE' with a good signal in the top left of ipad.
Any other ideas gratefully received before I make trip to John Lewis.
Many thanks for your suggestions so far.

If you tried everything there is nothing left to try, and the phone will never work again. But perhaps you didn't try EVERYTHING, so please describe the troubleshooting steps you have taken, and any error messages you have gotten when trying.
