I used jio network one month .I experienced very slow internet . It gives very profitable offers but the internet speed is very low. In some villages jio network is very poor.There no tower at many places .So I found difficulty in voice calling . The jio internet speed also very fluctuates.
So I can say jio is not faster as airtel .In my room jio speed is about 1.2mb to 2mb per sec but airtel speed is above 3mb without fluctuating speed. Also airtel gives best offer and service .
And so I suggest for best and fast internet sevice jio is not suitable, and one can use airtel network instead jio.
Thank you!
