This is my first try

Nokia 8250
IMEI : 350143303778645
Country / Provider : Australia / Optus

I used SmartDTC to calculate the code to unlock the phone. Here's what I got

#pw+978442104606644+7#

Can someone plz confirm me this number is correct ?

I tried to enter this number into the phone w/o the SIM card inserted and nothing happened. I didn't even get an error message. Is it normal ?

Do I have to be in Australia when I enter the code cause right now I am in Canada

Thank you for your help
