Xolo black one x is not very good mobile. Because you cannot use this phone with two sim and memory card. You could use with one sim and memory card or two sim. And you cannot change sim without sim changer pin. But it feature is very good in 10000 rupee.

So its feature is very good. But this mobile in some systamatic problems. I describe on up.
