First of all, let me tell you about the cons and pros of this device.
PROS: 1.ITS A 4G DEVICE 2.jio tv will be very helpfull for the live tv 3.battery is ok 4.little worth for 1500Rs
CONS: 1.over heating.some time it may explode 2.we cannot use other sims.only jio is compatible 3.whatsapp cannot be used 4.we have to return the phone after few months.and we will not be refunded.
So, overall this phone is not worthy even for a normal use.nokia 3310 is better if you go for a feature phone.
This is my review if the phone.hope this review is helpful.pls like if helpfull.
