Airalo eSIM Data Plans for Saint Martin

Airalo does not provide a truly unlimited data eSIM for Saint Martin. All of the plans that carry “Unlimited” in their name actually provide a 3GB/day allowance; once the daily limit is reached the speed is reduced to 1000 kbps.
Travelers who need more data can select fixed‑data plans instead, such as the 20GB plan valid for 15 days at $45 USD, the 10GB plan valid for 7 days at $26 USD, or other options listed in the catalogue. These give a larger data allowance and do not involve throttling after a limit is reached.

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.
