yaySIM does not provide any unlimited data eSIM option for India. All of its offerings for the country come with a fixed data cap that must be used within a specified validity period. For example, the IN_50_30 plan supplies 50GB of data for 30 days, while the AS‑20_50_180 plan gives 50GB for 180 days. Other higher‑cap choices, such as the 20GB plans valid for 30 days, are also available. Choosing a fixed‑data plan can be more cost‑effective unless a traveler expects to consume data beyond a few hundred gigabytes.
