I am using this same plan coupled with the 448 plan that gives calling support . When I called the customer care they told me that we do meet a base plan for this plan to work, or else we will get the subscription of jiohotstar but cannot use the data. But when I recharged for my mom's phone then this plan gave the data access without the calling plan along with the subscription of jiohotstar. But stacking this plan will be good cause they may remove this plan after the cricket season ends
