Jio would be good enough if it had limited customers but because of its welcome scheme of free talktime and unlimited data. Users are in n numbers which jio is unable to handle it seems.
Initially at its launch it worked like charm but still couldn't declare its speed 4g. But still satisfied.
As of now its speed has dropped equally to 2g speed.
Coming to free talktime, mostly its useless. Maximum response that I receive when calling is that the network is congested or busy. While in a call, the call drops even with full network.
Coverage is good.
