I purchased jio mobile which is only available on jio mobile store. this phone is only available when you book it otherwise you cant purchase.
jio phone is good for the people who are not able to handle android and it is even best for mother and father.
as jio phone camera is very bad , images is also get blur so there is no need of such cameras front as well as back. this phone is having only single sim. which only support jio sim, it only have jio application there is no facebook and whats app application. This mobile is having some smart features but the screen is very small according to these feature. Even you cannot get earphone with this mobile. speaker is also not good.
