The Jio sim no doubt is a milestone in the way of affordable telecom facilities.
But Jio is now not more than a trouble for people. The call is not connected in the first time. You need to try for more than three to four times to connect the call, still sometime it does not work. When the call is connected, the caller on the other side often complains of low voice or even no voice. There are frequent call drops, even when the networks are sufficient. Altogether, the calling experience is not so good or even disturbing.
