I just got a replacement phone and I need to unlock it. Also, is there a way to remove the TMobile settings. (Unbrand) I use ATT

How is this code entered into the phone?... Is this the "restriction code"?... I have a strange condition. My phone does work, but at times I get INSERT SIM, and then I get a screen that says "enter restriction code" and i can't get out of that screen without turning the phone off. After turning the phone back on it will work.
