USTronics is the worst! I bought a refurbished camera phone from them for my daughter. The pictures are so dark and cloudy, you can hardly even recognize who you're taking pictures of. And there's no way to hold the SIM card in place. I returned it as faulty merchandise, and they returned it to me saying I could work with the camera and that I shouldn't have expected more from a refurbished cell phone! So what about the issue of safety when the SIM card slides around??? My daughter couldn't get ahold of me her second day with the phone, nor I her, because the SIM card had slipped.
If you're smart, STAY AWAY from USTronics. It's a home-grown business. (Oh, and emails from them come from a gmail account, if that gives you any idea of how small town this company is.)
