Saily eSIM Data Plans for Saint Martin

Saily does not offer a truly unlimited data eSIM for Saint Martin. The plans that include “UNLIMITED” in their name provide a fixed high‑speed allowance of 30 GB; after that amount is used the speed is throttled (to 1000 kbps or 1 kbps depending on the plan). For travelers who need a large data allowance, Saily offers fixed‑data plans such as a 30 GB plan valid for 30 days or a 20 GB plan valid for 365 days, which provide a clear data cap and defined validity period without speed reductions after a limit is reached.

Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to check that these apps are accessible in Saint Martin before purchasing.
