I think jio become a big brand by its freeness to give Internet data and talk time for a couple of months. I accept that that time it had many problems but came up with new concept of 4G.
Nowadays jio is every were and it has many more offers and plans such as 3 months of unlimited talk time and 1 gb of daily data at price of 400, which is awesome. I tested it many times and the Internet network was fantastic service and 4G VolLTE was also exallent. Jio has been going great and giving other jio services like jio live TV, jiofi device was amazing and many other things. So high recommend you to shift to jio network and enjoy its fantastic services anywhere at anytime. Because I knew that jio future is bright. It’s service was too fast.
