Hello, I want to know if I go on O2 simplicity, (the basic one where you have no allowance and you just top up whenever you want and then use that credit for whatever, such as text, calls, the £1 a day for 3G Internet thing etc) can I use my home wifi service (from aol) on my phone for free and unlimited when I am at home? I am currently on the text & web tariff, where you top up £10 a month and get 300 texts, 500MB etc, but I want to switch to a cheaper tariff, the simplicity one where I can top up whenever, BUT I want to use wifi at home unlimited. Can someone explain which tariffs allow me to use unlimited wifi at home on my phone, thanks.
