Well, Do you have a brand new Nokia Phone and you wanted to use another sim card on another network … say if you are in another country and you want to use thier GSM network.. but your stupid tmobile phone is locked. Well… I got the solution for you. Go to www.nokiafree.org and get your unlock code. yep it worked for me and Hsiu hsiu. Yeah… and T-Mobile wanted me to wait 90 days and Nokia told me the code is 1234…. what an idiot. Anyway, go to nokiafree.org to get your free unlock code for your phone.
