Help me please, I've run out of ideas!


I can't receive data over the mobile phone network in any application. I've tried Facebook, Google and loads of others, they all say 'no data network connection'. Everything works fine when I'm connected via WiFi, it's just the mobile data that's the problem.


My APN settings are all correct (as shown at and I can still send and receive phone calls, messages and picture messages.

I've not had an email saying I'm blocked and there's no service outage because my wifi dongle is still working.

I have 945Mb data left of a 1Gb allowance.


I'm using a Sony Xperia Z with the latest versions of Android, and I've 'hard reset' the thing.


Any ideas? Please help!

Switch your phone off, then take battery out, then reboot your phone install all the settings and it should work

I'm sorry I thought when you bought a goody bag it was unlimited so it sounds like you haven't activated the Giffgaff settings in your phone it seems that your data is still on O2 tariff were you only get 1gig a month (Giffgaff has to be the best choice for data) goodybags with data for £12.00, or £15.00 for unlimited data BARGIN.

Thanks very much, but those are the very same settings I already had.

I've double checked them and rebooted - still no joy.

Thanks for trying though.

Thanks very much but I've tried that all with the exception of removing the battery, which isn't removable on the Xperia Z. Thanks for trying though, appreciated.
