I have been using Reliance Jio since 3 months and my experience is good but not great. Ambani has done a great job by pullin the crowd to use Jio. Undoubtedly its a dominant player in the market for mobile operators. But there are lot of call drops and many a times there is no network for Jio. The best way to use Jio is by having a dual sim card mobile so that when Jio is not working you can easily switch to the other mobile network in case of emergency. Jio is just a luxury and cannot be relied on during emergency because you cannot trust Jio with the network and call drops. Ensure to have a dual sim mobile so that you can take the benefit of Jio to the fullest
