ZenSim does not provide an unlimited‑data eSIM for Grenada. All ZenSim plans for this destination list a fixed data cap, with the largest options offering 20GB for 15 or 30 days. The plans that carry “Unlimited” in their name actually provide 3GB per day and reduce speed after that daily quota is reached; they do not provide unlimited high‑speed data. Travelers who need more data can choose one of the fixed high‑data plans, such as the Grenada 20GB for 15 days for $54.00 USD or the Grenada 20GB for 30 days for $59.40 USD, which offer larger allowances and no throttling once the data is used.
