Well....when you deliver a message to a contact on BBM,whats the icon that's next to your message?
If its a square timer box (thats red), it's probably cause either or your SIM card isn't inserted properly (try re-inserting), or you to re-activate your data plan
If its a check mark thats next to your message (without the "D" or "R" on top of it), probably the contact you've sent the message to, hasn't renewed his/her data plan!
You could always call up your carrier and ask them to help you out!
But do provide some more information on your issue!!
