Disable mobile data permanently A strange request I know... but I am quite keen to disable mobile data from my phone permanently (as opposed to just switching it off in the settings) so that I can only browse the internet when I'm connected to Wifi.

I've tried getting my network provider (O2) to do this with my account but they said it's not possible.

Is it possible to achieve this in Android instead? I'm basically just looking for a way to 'break' it... whether that's by installing some kind of app then that would be fine (perhaps if I could then return it back to normal with a factory reset)
You could delete your APN settings on your phone's configuration, or use airplane mode.
