Yes. ESIM.DOG offers unlimited data eSIMs for Grenada. The provider lists multiple unlimited plans with validity ranging from 1 day to 30 days. Prices start at $11.99 USD for a 1‑day plan and increase to $773.87 USD for a 30‑day plan. All these plans allow tethering, include speed throttling, and specify a maximum speed of either 512 kbps or 384 kbps.
The unlimited plans are subject to a Fair Usage Policy, so speeds may be reduced after heavy use. If a traveler is concerned about potential speed restrictions, they should contact ESIM.DOG to confirm the typical amount of data available at normal speed and whether FUP applies.
