Saily does not currently provide an unlimited data eSIM for Grenada. All of the plans available for that destination have fixed data allowances, ranging from 5 GB to 20 GB, and come with validity periods from 30 days to 365 days. The largest option is the Global 20 GB 365 days plan priced at $66.99 USD, which can be used in Grenada as well as 104 other countries.
If you need a large amount of data but not an unlimited plan, Saily offers several fixed data alternatives. For example, the Grenada 10 GB 30 days plan costs $37.99 USD, and the Grenada 5 GB 30 days plan is priced at $22.99 USD. Selecting a fixed data plan can be more cost‑effective unless you are a very heavy data user.
