Voyasim does not currently offer an unlimited data eSIM plan for Grenada. The available options are fixed data plans with set allowances.
The largest fixed plans for Grenada include the Grenada 20GB 30Days plan, which provides 20GB of high‑speed data valid for 30 days, and the Grenada 10GB 30Days plan, which offers 10GB of data for the same period. Choosing a fixed data plan can be more cost‑effective unless the traveler requires extremely high data usage beyond the provided allowance.
