Hello friends, I use both Airtel and Jio SIM. But I use Jio more because Jio's 4G speed comes better than other SIMs.I have been using Jio Sim for the past two years. There is no problem in running it in roaming.Since last 1 year, Jio has sold the most SIM.Today the network of Jio has become the most. I travel from one State to another state to go to my college every day. Yet it works equally in roaming.And there is no problem in running it Thanks guys Hope you all would have liked my review.
