️ CRITICAL COVERAGE WARNING: This eSIM connects ONLY to networks on the French Side (Saint Martin). It will NOT work if you cross into the Dutch Side (Sint Maarten - Philipsburg, SXM Airport, Maho, etc.). If you land at SXM Airport (Dutch Side), this plan will only activate once you cross the border into the French territory.
Escape Extreme International Roaming Charges
Don't let your carrier ruin your French Caribbean vacation with a surprise bill. Since Saint Martin is an overseas collectivity, it is often outside standard roaming zones, and using your home SIM card can result in massive roaming fees. A prepaid eSIM is the smartest way to lock in a fixed price for your data needs without any hidden surprises.

- Instant Connection: Get online as soon as you enter the French side or land at Grand Case-Espérance Airport (SFG).
- Massive Cost Savings: Compare our $2.11 starting price against expensive daily roaming passes. The savings are undeniable.
- Keep Your Home Number: Your WhatsApp, iMessage, and Telegram stay active with your original number, so you can text friends while using WestESIM for data.
- Reliable Coverage: We partner with top-tier local providers to ensure high-speed Saint Martin network coverage in the French region.

- Grand Case: Known as the gourmet capital; use your data to check restaurant reviews and book a table for an unforgettable dinner.
