Reliance jio phone we can say good if see the value of mobile.
but there sort of extra feature like that whatsapp google play and many more . for calling purpose there is no problem . also for video calling and many more. I used its last 15 days and basic on its use I give my review. customer service is good because when I call the customer for more enquiry of mobile they gives good response to me . one things is good that network of jio phone is available at everywhere . but to service no one say that charges is more they send your mobile at your billing address.
