Assalamu Alaikum, the phone is completely fresh. There are no problems with the phone, Alhamdulillah, it is completely fresh except for one issue: it slipped from the hand and a black spot appeared on the display because there was no glass protector on top. Other than that, there are no problems with the phone, SIM, and WiFi. You can use it to your heart's content. Security documents are available with the phone, whatever you ask for. 4/64 GB RAM ROM. Exchange is possible.
