Ist time some mobile operator brings a plan which is free for all I bought this jio plan in july and I got 3month free 4g net unlimited with free calling to local and std. Some times I got the speed of 28mbps in my phone. This is like the hight of awesomeness. Network coverage is good. Customer care is very responsive . but right now the outgoing : incoming call is like 40 : 10 so thats why the calling facilities is slightly messy .
