Hello, 
thank you for your message and sorry for the problems you have with your BB. 
Have you checked your Firewall Settings and Application Settings, to make sure, that all apps have access to the internet and are not blocked? Also do you use the phone on BIS or BES, meaning do you use it personally or are you connected to a corporate enterprise server? In the last case, their might be restrictions from your server administrator. 
I would try to go through all that and see if it works afterwards. Also go and check the application settings to make sure everything is correctly set up there.
The other thing I would look into is your router. Have you restarted your WiFi router as well? Checked on the Firewall there and everything?  
As for the datapackage: There are several people here on the forums, complaining, that WiFi does not have priority over mobile data. This means, that if you have a dataplan and activate WiFi, you would still browse using your dataplan and not WiFi, unless you a) either turn off your mobile data connection, which makes you unreachable for calls, sms, etc. or b) if you are a prepaid user, wait until your balance is depleted, in which case the mobile data won't work anymore and you will connect through WiFi.  
This is however different and should not affect you. Since you do not have a dataplan (at least that is what I understand from your posting), there is no dataplan to use and hence WiFi would have priority for connection with the net, since it is the only available source.  
I would give it a bet, that it has something to do with your phones settings in any way, or with the router itself (though this is probably unlikely). 
You can check your firewall settings by doing the following: Browse to your Settings Application or hit Options within any app. Go to advanced settings, check your security settings. You may also want to check your phones WiFi settings, by opening the connections app and open the WiFi configuration. 
Hope that helps, sincerely, 
Ben
