I know this phone has WiFi but my question is, does it cost extra monthly to use it? For example, if you want to call using WiFi or browse the web using WiFi (at your home network, or whatever)... I just don't want to pay extra for it.
It is free if you have T-Mobile service. T-Mobile lets you use the blackberry browser so there is no extra charge for wifi internet. If you want to make calls over it though there is a charge for that.
