So I traded a phone with someone who gave me a locked T-Mobile Samsung Galaxy Note 3. He told me it was locked and at first I declined the deal. But then I read about how easy it was to unlock (using purchased unlock codes) but now I can't seem to find the screen that prompts you to enter the information.
I have an active Metro PCS sim card and I tried using that and restoring the phone but through the whole process it never brings me to the "Sim Network Unlock Pin" screen. Does anyone know how to get there??
(PS, I apologize if this is in the wrong area or section. I'm just desperate for help)
