It may be because of your mobile is locked by some carrier so only it won't work in your country.
For unlocking your phone you can approach your service provider or else try to buy an unlocking service from any one of the online unlocking service provider like Unlock-Zone.com
Here you can unlock your Sony ericsson vivaz pro at low cost.
