This is Bestest 4G Network I ever used. I used this Reliance Jio network as my primary network. When I purchased this Reliance Jio sim I also suffer with some problems like it’s network issue and its internet speed issue. But when I call the Customer Service, they are very polite and easily resolve my problem very fast. Now I enjoy fastest speed of 4G network and its recharge value is also reasonable. I can easily download movies in just 10 minutes with the speed of 9-10 Mbps. I have prepaid sim so their is no other billing charges. So in short this is the best 4G network with best customer service and charges. I recommend everyone to use this Reliance Jio Sim.
