There is no screen lock on the phone (pin) however when I try to set it up it says I must enter a Google email that was associated with the phone. I didn't know this would be an issue. I bought it from somebody on Craigslist. After made a call and showed me the phone still worked. He factory reset it. I haven't been able to reach him since. The phone is white, it takes sim cards, and was originally made for T-Mobile. Please feel free to contact me with any questions you might have. Have a good day.
