iPhone 4 - Suddenly can't connect to the internet anymore

Hi,

I'm having the exact same issue. I'm got the iPhone 4S on Orange and it has no connectivity to any 3G/data, no internet/apps work unless over WiFi.

This is all post iOS 5.1 update. Have restarted and turned all data/3G/roaming off and on again to no avail.

Not sure why this would effect us both if you're on iOS 4.x and I'm on 5.1, maybe an issue with Orange?

Sounds like you're in iOS 5, if you have iMessage, notificiations that you pull down from the top of the screen etc then you're on iOS 5. It might be worth upgrading to iOS 5.1 to see if it fixes the issue for you.

I upgraded last night and the issue started straight away I guess, but only figured out this morning when I left my house and WiFi for work. Seems strange it effects us both and the only constant variable is we're both on Orange.

Maybe they have a connectivity issue with their towers?

I too have just upgraded to iOS 5.1 from 5.01 and now cannot connect to 3G. I have full 3G signal but no matter what I do I cannot get it too connect. Every time I try and open the App Store I get the "Could not activate cellular data network". Have tried restarting with no luck. I am also on the Orange UK network in the London area; had no issues this morning in the same area.

Just spoke to Orange, they have a global data issue, down currently worldwide for most users, possibly for the next 48 hours. At least we all know it's not an iOS issue.

You can check for updates with Orange by calling 150 from your Orange handset. Well this is going to be a very boring 48 hours!

Thanks thedirtybadger. Just got off the phone to Orange and got told a similar thing.

Ditto and i had just done the ios update also.

I was quite worried

Hi guys,

I guess this issue is related to IOS as I am experiencing your same problem. Yesterday evening data connection was working fine. This morning after the download of the latest version everything seemed to be fine at home (I was connected to my WI FI) and now at work, although the 3G signal appears on my screen I am unable to connect to the internet....I am in Belgium and using a local provider...

cheers

I wonder if this http://www.bbc.co.uk/news/science-environment-17295337 has anything to do with it all?

Yes it's orange geting same thing..

Hi guys,

I encountered the same issue after I made the update to iOS 5.1 on my Iphone 4S, the problem was that after the update the internet settings were changed so I advice to make the settings again: Settings->General->Network->Cellular Data Network and make those settings again.

I'm on Vodafone RO prepay and for example at APN I have live.pre.vodafone.com and after the update the "pre" was dissapeared

IMPORTANT: After you make the changes reboot your phone

I hope it helps

UPDATED:

Hi all,

It's confirmed it's the Orange Data Network that's out nothing to do with your phones http://www.theregister.co.uk/2012/03/08/orange_down/

Hopefully they will sort it out soon.

I called and eventually got someone who knew what he was talking about. I knew it wasn't a generic Orange 3G / data problem as I'm typing this on my Orange iPad!

It turns out is is a voice network data APN issue. Must be major and they have no idea of when it will be fixed.

**** shame you can't edit APN info on Orange iPhones, as I could just change it to the iPad's!

I have iPhone 4 on Orange and have the same problem. Called the Orange call centre who told me they are being affected by the increased solar activity (weird as I'm typing this on my iPad!!!) and there's nothing they can do about it...
