Yesim offers unlimited data eSIM plans that cover Saint Lucia.

All of these plans are flagged as unlimited data, but normal speeds may be capped because of a Fair Usage Policy.

Under the Fair Usage Policy, speeds may be reduced after heavy usage. If a traveller is concerned about potential throttling, they should contact Yesim for confirmation of how the policy is applied and the expected amount of data that remains at normal speed.
