I unlocked my phone. I called t-mobile to get the unlock code. they will give you one unlock code every 90 days. then they email it to you after an hour or so. and then fallow the directions.....
This is the email they sent
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your Samsung device. Please be advised a non T-Mobile SIM card MUST be used to unlock this device.
- Insert a NON T-Mobile SIM & turn Device on
- The Device will automatically prompt you to enter code into an empty field.
- Tap in the empty field above the "Unlock & Dismiss" options (this will display a key pad on the screen).
- Using the key pad input the Unlock Code provided by T-Mobile.
- Press the Back button to remove the keyboard from screen.
- Tap the "Unlock" option; handset should display "Network Unlock Successful".
Thank You,
