Dear if you want to unlock this unique and wonderful phone, then just b130s for unlock but not supported by ust box & it shows always error on spt. so just use this code to unlock phone with no failure.
steps to follow
1- Insert Motorola Test Card.
3- Personalise unlock code : *7465625*638*00000000*00000000#
4- unlock phone : #7465625*638*00000000#
after that phone is unlock.
and pz confirm the same , as when u test it by yourself.
