There cant be a connection better then jio. can not even talk about wifi without saying jio dongle . the color. battery life . size of dongle.the jio sim is cheaper. as well as jio dongle is also cheaper. plus the performance is much much better than other brands like airtel, idea etc. this is a life saver I must say. I work from home and without a high speed internet its not possible to keep working. but jio never annoyed us. love it. everything about it is just fantastic.
