Jio 4G phone is the best phone under 2k. It comes with very great battery life and 4G volte support which is amazing for a phone under 2k.It also comes with camera on both sides of the phone.Selfie camera is to provide video calling facility.I have used it for about 3 months it doesn’t have any issue.Its video calling quality is not bad it is of average quality.But in this price range video calling won’t be evem imagined.If you are looking for a secondary device you should buy this phone. I promose you this investment wouldn’t be in loss.
