I am using Jio network since 4 months and my experience is satisfactory till now. I got the Jio preview offer which is unlimited data, calling, sms and other features like free subscription to their apps. I got the ftee sim with my Reliance Lyf device. The data connectivity of Jio is superb.its a high speed internet. I usually get the speed of 20-30 Mbps. And the apps are awesome and quite useful. However, sometimes I face issue with call connectivity. Hope Jio resolves their issue of call drops with other operators. Jio is now offering welcome offer for anybody who has got 4G phone. You can enjoy the free services till 31st December. After that you can choose a plan according to your needs. As jio runs on Volte services, if you have a volte device, you can enjoy jio’s voice services but if you have 4g phone which is not volte, you can still enjoy voice services by downloading JioJoin app. Overall, its a nice experience with Jio till now. Hope it continues to be an amazing journey.
