Wifi is always free, 3G will be free whilst you have your data allowance, but you may be stopped if you go over. In general it's always wise to use wifi if available.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
