nextSIM does not have a plan that truly offers unlimited high‑speed data for Grenada. All available plans feature a fixed data allowance, such as the eSIM Unlimited Standard 1 Day Grenada which includes 1 GB of data and a reduced speed of 512 kbps after the limit is reached. Plans with “Unlimited” in the name are only marketing terms; they still provide a set amount of data before throttling.
If a traveler needs more data, nextSIM offers larger fixed‑data options. For example, the eSIM 20GB 30 Days Grenada provides 20 GB of high‑speed data for a month, and the eSIM GLOBAL 50GB 30Days Premium gives 50 GB for 30 days with coverage that extends beyond Grenada. Choosing one of these fixed‑data plans can be more cost‑effective for users who require substantial data but are not extremely heavy data consumers.
