There is a problem with the IC inside its SIM tray so the SIM doesn't work. Only Wi-Fi is all okay. Gaming, video streaming all 100 percent okay. Display is full fresh. When the SIM problem was being checked, it was opened once, that was the only issue. Apart from that, it has never been opened. No box or charger. Charger was not given at the time of purchase and the box was lost. Security can be provided.
