I have a BlackBerry Curve 9300. In my Mobile Network, I need to have my Data Services on for certain features for my Blackberry Social add-on (e.g., BBM, Social Media). Will I be charged for data usage?
No, BlackBerry is unique in that on the older BIS services carriers could customize packages to allow data only for certain features. If you have the BlackBerry social add on then data can only be used for those items. So if you try something and it doesn't work that means it's not part of your package.
