First of all thanks to reliance for giving free card that is Reliance jio. With the help of this we can do free calling, free internet, free messages etc. With the help of free internet we can learn anything from the internet and do anything. I am using this Jio card. With the help of this Jio card I have completed my college project also because of the free internet I could slove every query from the google. But sometime the speed of the connection is very low so that we can not able to call if it is argent. Cutomer Services is very nice.
