Few questions about speed dial and internet options on Blackberry Curve 8330


I just got the phone today but so far it has proven to be pretty easy to get accustomed to. My questions are:


*I know how to set speed dials but then when I go to push the speed dial number it doesn't bring up the contact chosen for that number...help?


*I didn't get the unlimited email/data plan for blackberry so my questions for this particular area is do I need to manually turn off my internet connections when they are not in use? How do I do this, if needed? If I am not connected to the internet can I still call out/receive calls? When I try to call outit asks for me to restore connections/turn on radio..why is that? What should I do to stop this?


Thank you so much in advance for anyone who can answer these 😃
