@Gobinaath bro. Can you come to home menu by pressing red button than press jio button? It will show the notification menu. We cab see whether wifi option is there or not.
Technically I would not recommend you that.
It's android and not how you try it required a good RAM and that's why it hang a alot.
So, would recommend you to go with LAVA Z or IN 1b or 2b and that with 3GB+ varient.
