I don't know anything about it, it's been with me for a long time, but what I remember is that the SIM card slot was broken and I did some modification, but I don't know if it works or not, that's all I remember. The device has scratches. The phone is rare and hard to find. Regarding the projector, based on my experience, it is working (but I don't guarantee anything). I will sell it as is. Whoever wants to take it for parts or do whatever they wish with it. Price: 150
