No, yaySIM does not provide an unlimited‑data eSIM plan for Grenada. All of the plans listed for this destination are fixed‑data bundles, each with a hard cap that must be used within 30 days.
For travelers who still need a large amount of data, yaySIM offers several high‑capacity options. The 20GB bundle for 30 days costs $95.89 USD, while 10GB and 5GB bundles are available for $49.01 USD and $34.49 USD respectively. Choosing a fixed data plan can be more cost effective unless the user is an extremely heavy data consumer.
