Had a Sony Xperia Z3 on the contract and long story short; I'm on my second handset and even this one cracked in my pocket as well (both times with a case on). I forked out £180 for the repair the first time. Instead of fixing it they gave me a brand new phone, but a few weeks later this one also cracked in my pocket, and I have been using an iPhone 5 since that time that I acquired from a family member. For some reason I can't use the 2GB of 4G data that I am paying for on this iPhone.

So I'm effectively forking out nearly £40 a month for unlimited calls & texts on an iPhone 5 with no data.

I can't afford to keep paying £180 everytime Sony's poorly made "flagship" phone cracks in my pocket .

Someone, for the love of all things good in this world. Help me. Someone, please, help me.

P.S. If you hear anyone thinking of getting the Z3, warn them not to bother. Not only is it not as durable as Sony have made it out to be, the OS is incredibly buggy and flawed, causing apps to crash and the phone to turn itself off from time to time.

If you have switched phones the APN settings will be different, check them here: http://www.geeksquad.co.uk/articles/o2-apn-settings#o2%20iPhone%20APN%20MMS%20mobile%20internet%20se...

The APN settings already seem to be exactly what you need for an iPhone and 3G comes up at the top of my phone but I still can't use any apps that require internet and I get the same error message everytime; 'You are not subscribed to a cellular network provider.'

I'm lost.

You have the wrong data bolt on, switch the APN to "mobile.o2.co.uk" and it will work.

It's the Android setting you need not the iPhone ones.
