I had buy it from Baldev Plaza which is in Gorakhpur, U.P.It cost is 10000 when launced.In starting it has the feature of volte but after some updates ( when it changes from lollipop to marshmallow) it looses the feature of volte which the most useful feature of a 4G smartphone to talk over lte.Its speed is good but if it used for long time then it starts hanging.
