I have bought coolpad mega 3 4G mobile on amazon. It also supports JIO 4G. It wortg only 7000 Rs. I am using it from two weeks. I have checked all tge features. The speed of the phone is very fast. If we are downloading something on background, it doesn’t really interrupts tge speed ofbtge phone. It has in-built beauty camera. I’ve never liked my own photos before clicking it on this mobile. I don’t think that any other mobile would give the performance like this at this price. The screen is 5’5 inches long. The screen has full HD display. It has standby time of 150 hours. It has 8 MP camera. We can insert external SD card upto 32 GB. In short, It is a must buy phone. If you’re looking to buy a 4G phone for JIO or etc. on your budget, its the best phone for you.
