That's the problem with Vivo in general. Their phones always seem overpriced. Does anyone even know the price for the Xplay 6? Outside of India where could you actually buy one anyway? Here in the Philippines we only have some of the Y and V series. No Xplay.
Just from china, I believe is the only option. In thailand there were once xplay and x series but since not good marketing so now there are only v and y series just like yours.
