Reliance Jio says they gave 4G free for 3 months for 4G phones. And buy it I using it. But it doesn't feel like 4G. I used many connections, jio 4G speed feels like Idea and Aircel's 3G speed sometimes I coudn't get that speed too. What's the point of selling this Sim as 4G that doesn't support on any 3G phones? When it can only give 3G speed. Giving internet free for 3 months thats good. Advertise it as a 3G sim is better.
