So I just downloaded the App "WhatsApp" onto my blackberry from App World.
I've been using it for a few days, until it just now hit me that it's probably costing me money, considering I have no data whatsoever included in my Blackberry plan.
I know that if I'm connected to Wifi, then it won't cost me a thing.
But if I receive or send any messages when I'm not connected, how much will it cost me?


Thanks
