Hello I recently purchased a Razr XT912 Verizon for use with my Optus sim card in Australia. I managed to upgrade it to 4.1.2 JB fine then root it with "Dan Rosenberg's DROID RAZR 4.1 Jellybean exploit called 'RAZR Blade'" Call's and SMS work fine but mobile data does not either does call forwarding (In relation to extending ring time), When trying to do that it fails to call and gives me the message "Call forward is disabled outside the Verizon Wireless network".
Any help would be greatly appreciated
