I purchased a BlackBerry 9300 VIVO. IMEI is not on the Blacklist, network engineering menu appears disabled. Before the release contained "10 left", which proves that the unit had not suffered any attempt to unlock a subsidy code.
After inserting chip operadiras other GSM signal remains "SOS" as if the device were still locked.

The device has PTT (VIVO direct). Is there any connection with this specific model functionality with other carriers?

I await help from colleagues safos.
