Airalo eSIM Data Plans for Saint Martin

Airalo does not provide a truly unlimited high‑speed data plan for Saint Martin. Every plan labeled “Unlimited” gives 3 GB of high‑speed data per day; after that amount the data speed is throttled to 1 Mbps. Travelers who need more data without the daily limit can instead choose a fixed data plan, such as the Marnet 20 GB plan (valid 15 days or 30 days) or the Marnet 10 GB plan (valid 7 days or 15 days).

Airalo does not offer a Saint Martin eSIM that includes a phone number or SMS functionality. Travelers can purchase a data‑only plan and use VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages, provided those services are available in Saint Martin. Because some destinations may block or restrict certain apps or VoIP services, it is advisable to confirm that the messaging or calling apps you rely on are accessible before buying a plan.

Airalo provides 17 single‑country plans and 21 multi‑country plans for Saint Martin. The available plans span a price range of about $6 to $160 and data caps from 1 GB up to 20 GB. Among them, a portion uses a daily data cap that resets each day, while the rest offer a fixed data amount for the entire validity period.
