Reliance Jio is very good to use internet either by opting this one with Lyf mobile handset or by buying a free Jio 4G SIM, available at miny stores. But as the company have given the benefits of free calling and messaging along with this one, for all over India. This facility is good but the problem is in call connectivity. It will not get connected by a single dial always. You always have to dial, dial and dial at least for 10 times.may be more. Overall the internet service is superb but have ridiculous experience with its call connectivity.
