Intex aqua star 4G is a great product with a small budget
according to is price it a good phone.
I m using it and it is working fine no problem faced by me in this product.
but its RAM is only 1GB which is not sufficient for installing too many apps.
I suggest to installed only important apps not games or other garbegs.
if you does not afford a very costly mobile then you can buy this mobile in a low budget.
