Reliance Jio offers a data plan with 1-year validity and 2GB data per day. Once the data quota is used up, the speed reduces to 64kbps and becomes unlimited. The plan does not include additional benefits like calling, SMS, or OTT subscriptions. However, the plan may not be worth it as there are other annual plans with more benefits available at similar prices. The data plan is relatively more expensive compared to other unlimited plans from Reliance Jio.
