On my SCH-T300 from Verizon I can enter the NAM programming mode by entering MENU, 60, '000000'. There is a Mobile Country Code menu option, but there is no Mobile Network Code (MNC) option! I can change the MCC to '250' (Russia), no problem. But I need also to change the MNC to '01', otherwise our local CDMA operator in Moscow is refusing the activation.

Question: how can I change the home Mobile Network Code (MNC) in a Verizon's SCH-T300?

Any help will be appreciated!
