    I unlocked my Verizon Blackberry 9550 and after the reboot it says "Searching for GSM..." , after some time may be 2-3 minutes it says no service, following are my settings for Mobile network, i have ATT sim card in the phone.

    Network Select Mode : Automatic
    Network Technology: GSM /UMTs
    Network Mode : 2G

    any help is greatly appreciated, thanks very much in advance.

    There maybe an issue with the SIM ? Have you tried a different sim ? If so, they there is any issue with the antenna.

    Try to search for the network manually, set the molbile network manually on your unlocked Blackberry and search for AT&T see if it's works and let us know.
