Yes,its security mastercode,not unlock code.

 

OK. How can i unlock it to t-mobile network instead as the security code is not working please?

 

Your question was about security code,not unlock code.
And i dont know,locked your phone or not.
Security and unlock codes are difference things.
I gave you security mastercode for your mobile.Work or not-itsnot my problem,if you want ,ask your provider about security code.I have only this.Somitimes security code work,sometime not.
Try once more switch on-off the phone.
