Zwitchy does not provide a true unlimited data eSIM for Grenada. The plans branded “Grenada · Unlimited – X days” give a fixed allowance of 1 GB per day and apply a reduced speed of 1000 kbps after that limit, so the data is capped on a daily basis.
Instead, fixed data packages are available, such as the 10 GB plan for 30 days priced at $82.00 USD, or the 30 GB plan for 30 days priced at $236.50 USD. These offer larger, unthrottled data allowances for travelers who need more bandwidth.
