Blackberry 9800 : No valid Sim card

Hi,

I received a used-bb 9800 (Vodafone).

I need to switch operator (new sim-card from employer) but I receive the message 'No valid sim card'
The new sim-card works on other phone.

Is my bb 'provider'-locked? or is the phone dead?

Thanks for your time to help me.

Your phone sounds like its not sim unlocked. To see if your sim is unlocked or not, go to Options> Advanced Options> SIM Card. If at the top of the screen it does not say "security disabled", then you'll need to unlock the sim to get it to work on another network.
