Blackberry pearl 8100 prob.

Hello,
ok so I made my blackberry phone number private once to make a call that I didn't want the other person seeing my number. But after that, all of my out-going calls became private as well. It is soooooooooooo annoying! Cause now no one answers my calls since it keeps coming up as private on their cell's. Can someone help me fix this problem cause I really can't take it any longer.

Thank you!
