Iphone 5 3G not working

[Anonymous]

Ok, i've had it over a year and the software is up to date.  The 3G has just suddenly stopped working about 3 days ago and I'm at my wit's end.  Its fine on wifi.  I've tried everything I can see online.

I've restored it to factory settings, no joy.  I've switched off 3G to see if the basic mobile internet works.  It doesn't. I've gone to settings > carrier and switched it from automatic to selecting 02-Uk and that didn't work.  I've gone to 'Cellular data network', made sure the settings are as they should be according to other sources.  I've reset those settings and that hasn't worked.

And people around me also on O2 don't have any issues with it so its not a service thing.

Can anyone help me?

Ensure airplane mode is not turned on.

Hold the Top Button and Home Button until the Apple Logo appears, and then let go of both. Your iPhone will reset.

Check your apn settings.

Text ACTIVE to 2020. . Save the settings and re boot.

Apns are here too. http://www.geeksquad.co.uk/articles/o2-apn-settings

Try settings , general , reset , reset network settings.

Check your service status and clean Your sim.

You Could make a genius bar appointment at your most local apple store to have it checked.

Sorry to add ensure you have data left in your allowance.

Contact O2 Cs on 202 contract or 4445 payg to have your account checked over.

Is 3g still showing on the status bar?
Contract or pay phone?

bandofbrothers - I've tried all of the above.

MI5 Its a contract and yeah the 3G icon shows on the phone, usually with a healthy amount of bars.

So if you've gone through all the generic solutions then I would try your SIM card in another phone. SIM card adapters are free from O2 shops. This would make your nano sim into a micro sim for example. Process of elimination.

The last suggestion I made was a Genius Bar Appointment. Have you managed to arrange one.

What did CS say when you called them?
You do definitely still have data left this month and not used it all up too ?

Ok, I was going to book a genius but then I happened to notice on my online account it said all my data had been used up.  I was pretty surprised as this has almost never happened, and not with so long of my billing period left. I checked my texts from O2 and there was none of the "You've used 80% of your data this month" texts from them for this billing period.  

However I then purchased another 100MB bolt on for £3, my 3G started working so all I did was check a few emails.  Then I get a text saying I've used up 80% of my data allowance.  I don't know if it means 80% of the 100MB already (within 3 mins of purchase?) or it somehow refers to my original data allowance.  Like I said I certainly received no texts this billing period from them prior to today.

You need to check in your data usage for what is using it so quickly.

It is quite common with iPhones as they consume a lot of data, for various reasons...
