I recently bought this Jio phone, and found value for money even though it had few pros and cons
The best thing is its simple design and the cost of phone is less ( ₹1500) and the display is fairly ok, very easy to operate and user friendly.
The main drawbacks in this phone is its low battery capacity ( 2000mah) which will not last long for a day. Also the camera clarity would have been much better.
Jio offers 500MB data daily on recharge of 150₹/month which is fairly good. And it assures for a buy back for ₹1000 after an year usage, which is a good deal.
Expect Jio to launch better smartphones in future.
