Help: 'sim not provisioned' shows on my blackberry . I need ur help pls

I think the fone is locked to a network. So u have to unlock the phone first.

What country are trying to use this blackberry device in ?

It is not the phone problem. The 'sim' is not prepared to access the internet. You need to activate internet provision on your 'sim' fro your provider.
