sim unlock for sony z3 compact

[amira3]

My friend bought a phone for me from Japan . It is sony docomo . I tried to put my sim card but it is asking for some code to unlock it . I was wondering if you can help me with this problem . And thank you

You need to contact docomo for unlock,although the devices from docomo might only work in their network. Perhaps your Local support knows more.
