I would like to tell you that the speed of this jio is mindblowing.i am using the jio since 3 march.and I have no complaint against this.the network coverage is everywhere in india.even idea airtel do not have the network like jio.this is the easy way for changing the speed of any device.i used about 1032 gb till. this is free of cost also.from december 31 it gives only 1 gb a day.but in morning 2 am to 5 am it is unlimited and speed is around 5 to 10 mbps.people are so happy by using jio.i am highly obliged to ambani sir for launching jio with free of cost.it is free for 31 march.so it does not contain any chareges.jio crosses about 50 million customers.
