Hello there and welcome to the community.
For Blackberry devices,using firmware before BB10,you need to purchase the Blackberry ADD ON,to access Blackberry services,Including emails/browser/internet.
*You need to buy this at the exact same time as a goodybag and it can NOT be added part way through,AFTER buying a goodybag,Unfortunatley*.
If you have,these settings will work.
If NOT,you now need to wait for your current goodybag to expire, and make sure that you buy both goodybag and add on,at the same time,next time around Unfortunatley,but dont worry.
Here's an alternative for you to use,if you have NOT purchased the Blackberry ADD ON,at the same time as your goodybag.
Please take the time to read this,if you want to use your internet,without the BB add on,cheers.
