Hello,

It looks like the telephone is SIM locked.

If you go to Options > Advanced Options > SIM Card and type MEPD.

This will bring up another screen. If the Network option shows "Disabled" then it is unlocked.

If its locked go back to the seller or buy an unlock code online.

Hope it helped.

I have a blackberry 7290 how do i reset to factory setting


You need to get it unlocked either by doing a search for unlocking blackberry 7290 and paying one of the online services.

Service providers will unlock their phones as well just tell them your traveling abroad and you need to unlock the phone. Otherwise if it is not affiliated with a service provider you will most likely have to pay someone to get you unlock code.
