Prepaid data plans for French Saint Martin
Every plan is data-only and covers the French side of the island. You receive a QR code by email within minutes of purchase, install the eSIM profile on your device, and activate it when you arrive. Data packages start at 1GB valid for 7 days, with larger bundles available for longer stays or heavier use.
Plans connect to the local mobile network using 4G/LTE or 5G where the underlying network and your device support it. You can browse, navigate, message over the internet, and share your connection with other devices via hotspot. Voice calls and SMS are not included, though you can use internet-based calling apps over your data allowance.
How to set up your eSIM for Saint Martin
Check that your phone supports eSIM technology before you buy. Most recent iPhones, Samsung Galaxy models, and Google Pixels are compatible. Once you complete your purchase, the QR code arrives by email. Install the eSIM profile while you still have WiFi, either at home or at the airport, but leave it turned off until you land.
When you arrive in French Saint Martin, enable the eSIM data line in your phone settings and turn on data roaming for that line only. The profile connects automatically. Your home SIM stays in the phone, so you can still receive verification codes or calls to your usual number while using the eSIM for data.
Staying connected around French Saint Martin
Marigot, Grand Case, and the main coastal towns have reliable mobile coverage. You will have connectivity along the coast road between Orient Bay and Friar's Bay, and most beaches on the French side are well covered. Navigation apps work throughout the developed areas, and rideshare or restaurant bookings will load without issue. Coverage thins in the interior hills near Pic Paradis, though the island is small enough that most travellers stay near the shore.
A 1GB plan is enough for a week of maps, messaging, and occasional browsing. If you are uploading photos from the beaches, streaming music while driving between Grand Case and Marigot, or working remotely from a villa, consider a larger bundle. Many cafés and hotels offer WiFi, but having your own data means you stay connected on boat trips to Tintamarre or Pinel Island, and at beach bars where the WiFi signal does not reach.
Frequently asked questions
Does the eSIM work on both the French and Dutch sides of the island?
These plans cover French Saint Martin only. If you cross to the Dutch side (Sint Maarten), coverage depends on the specific plan. Check the plan details before purchase if you intend to spend time on both sides of the island.
Can I buy the eSIM after I arrive in Saint Martin?
Yes. You can purchase and receive the QR code while already on the island, as long as you have internet access via WiFi. Install and activate the profile, and you will have mobile data within minutes.
Will my phone work with an eSIM in Saint Martin?
Your device must support eSIM technology and be carrier-unlocked. Recent iPhones from XS onward, Samsung Galaxy S20 and newer, and Google Pixel 3 and later all support eSIM. Check your phone specifications to confirm before buying.
How much data do I need for a week in Saint Martin?
A 1GB plan covers maps, messaging, and light browsing for seven days. If you plan to upload photos, stream content, or use video calls regularly, choose a 3GB or larger bundle to avoid running out mid-trip.
Can I use my eSIM as a mobile hotspot?
Yes. You can share your data connection with other devices via hotspot. Be aware that tethering uses data faster, so choose a larger plan if you intend to connect a laptop or share with travel companions.
