I am so disapointed from Internet speed of jio from 2 months . In starting they provide best speed but jio sim internet speed is so low . Some time its work like 2G internet speed . Its downloading speed is some time goes down at 15-20kb/sec. And high speed of this 100 - 200kb/sec. Some time. It will not cross 200kb . And its coustmer service is bad expierience for me some time.
