Being charged for data usage despite only (knowingly) using Wi-Fi.

[Anonymous]

I've had some trouble with this for quite some time, I've been using a SonyEricsson Xperia U ST25i and despite having 'Data Roming' disabled and the 'Data enabled' option not enabled. I'm being charged for data usage despite only even (knowingly) connecting to Wi-Fi (my phone is usually not connected to the internet, and when it is, it's connected to a household Wi-Fi).

I've read a lot about this in other forums, so I know that O2 isn't scamming me so I'm wondering, what setting have I missed?

Find the data apn and remove it completely from the phone. This won't effect wifi but it will stop a connection to o2's data servers.

Follow @MI5 advice or alternatively, call customer services and request a GPRS data bar. This will also prevent data use on your handset but will still be able to use WiFi

Thanks guys, hopefully that's fixed it.

It should do, but let us know either way

That is great and quick advice @redtitbit and @MI5!
