Hi,

This is true.. the problem with tracfones is that they are very hard to unlock..
You could try by unlock codes at http://www.unlocksamsungonline.com/samsung-unlock-codes/

however by cable will not work. Before you purchase any unlock by codes service check if you can enter the unlock codes.

Put a different simcard in the phone and turn it on. Then let me know exactly what the phone says..

You did wrong step my friend, if your phone locked by sim card you need puk code to unlock samsung sgh-x830 sim lock pin. This puk code is unique and you only can get that from your network provider, that's what is going to be happened if you just insert any puk code from internet to unlock samsung sim card. Now the only option that you have is call your network provider and explain to them your condition, i hope your sim card can be unlocked otherwise you must change new sim card.

here in our country problem like that ... we emdiately consult our technician... cause it cannot manualy retreive the codes we used software to unlock and refresh the code... try find a technician ....
