There are a few reasons for this. Firstly, Chinese manufacturers tend to focus on the domestic market, which is much larger than the US market. Therefore, they are not as motivated to sell their phones in the US. Secondly, Chinese phones often lack the necessary certifications to be sold on Amazon. For example, they may not have the necessary network band support or they may not have passed safety tests. Finally, Chinese phones tend to be lower quality than phones from established brands like Samsung or Apple. This is particularly true of the cheapest Chinese phones, which are often made with recycled or counterfeit components.
