I used this mobile from 3 month . The most useful thing on this mobile is their low data used & low packs.this mobile used very less internet data to run internet.jio provide unlimited calls and messages in only ₹49. This phone can’t have hotspots ??.and another’s Sims like Airtel; Vodafone can’t work in this phone.but this mobile volume is very loud which is gud feature in this mobile. Camera quality is poor. specially I recommend this mobile to old people’s which cannot know how to used smartphone.this mobile is very useful and easy to used for that.
