I unlocked my Docomo at the store:
https://www.nttdocomo.co.jp/english/supp...nlock_dcm/

Is this the same as "Region Unlocked"? Will my Galaxy Note 2 be able to use a readysim or at&t sim card and have a phone number? (I dont know if DOCOMO japan is GSM based or CDMA)

Anyone know? Thanks!

Yes it should work, yes that is region unlocked.

Thank you very much! Ok cool, will now order a ATT Sim online from amazon before visiting home and should now be able to have a us fone number for a few weeks. The fee of unlocking the phone officially was 3000 yen from docomo

Cheers guiys and thanks afgagain!!
