Wiiline eSIM Data Plans for Saint Martin

Wiiline does not provide a truly unlimited eSIM plan for Saint Martin. The plans that carry “Unlimited” in their name actually give a fixed amount of high‑speed data: each offers 2GB per day for a set validity window of 3, 5, 7 or 10 days. Once the daily 2GB is used, the speed is throttled to 1 Mbps.

Travelers can still choose one of these fixed data options. For instance, the 7‑day plan gives 2GB every day for seven days at 4G/5G speeds before throttling, and the 10‑day plan provides the same 2GB/day for ten days. These plans allow consistent high‑speed data for the duration of their validity and are available as alternatives to an unrestricted data service.

Wiiline does not offer any Saint Martin eSIM plans that include a phone number or SMS capability. The available plans are only data‑only. Travelers who need to communicate while in Saint Martin can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, because some destinations block or restrict certain apps or VoIP services, it is advisable to confirm that the apps you rely on work in Saint Martin before purchasing a Wiiline eSIM.

Wiiline provides 11 single‑country data plans that cover only Saint Martin and an additional 80 multi‑country plans that include Saint Martin among their coverage zones. The available plans range from $8 USD to $270 USD and offer data caps between 1 GB and 100 GB. The catalogue includes both fixed‑data‑cap offers, which grant a set amount of data for the entire validity period, and daily‑data‑cap offers, which allot a specific amount each day.
