The jio phone is a good feature phone and it offers a lot os specifications for a small amount but it works slower after 1 hours of continous use and stats to heat . over all its a best feature phone and the the company is offering a lots of more specs in a little amount .The user experience of mine is good with this mobile phone and after all its good choice for mobile users who want to experiance 4g speed in low budjet and this phone does not supports any other brand sim card it is the weak point of this device
