3 network data not working on iphone 5?

Ok so I just noticed when I went to use my phone that my Internet wasn't working it would show 3G in the top but when I went on anything that uses the Internet it just pops up could not activate mobile data network? I just got the phone on Thursday so I doubt it's that anyone help?

Don't worry there's a simple solution and it involves buying an android… AND YOUR DONE have a good life

Did it happen around 10/10:30 because my Iphone 4s is doing the same thing. It must be 3. Just wait till the morning and if It hasn't fixed itself take phone to a shop or ring up 3s customer service

I'm also experiencing this problem - my iPhone 5's Internet was working fine earlier and has been since October when I bought it but at around 22:00 today (Monday) it suddenly stopped working. I would either try and contact 3, go to a 3Store or just wait a few days and see what happens. Hope this helps:-)

Mine is doing the same! I can make text and calls but no Internet unless I go on wireless

Unlike what Dylan said I think it's 3 in general and noticed my mobile data on my Samsung Galaxy S3 which happens to be an android is doing the same as yours so hopefully it will be sorted later
