Wanderly lists 6 fixed-data Saint Martin plans, ranging from 1GB up to 20GB over 7 to 30 days. Prices start at $1.99, and the lowest cost per gigabyte is $0.65/GB on the 20GB 30-day plan.
Unlimited day-passes are also available from $1.99 per day, billed per day rather than per gigabyte. All 11 Saint Martin plans can be topped up without reinstalling the eSIM.
Every plan is data-only and installs from a QR code, so your home number stays active on its own line. Validity starts when the eSIM first connects to a network in Saint Martin, not at purchase, which means you can install before you fly.
Everything travelers ask before buying a Saint Martin data plan.
After purchase you'll receive a QR code by email. Scan it from your phone's cellular settings to install the Saint Martin eSIM. Install over a reliable internet connection, then follow the activation instructions supplied with your plan.
Your phone must support eSIM and be carrier-unlocked. Support varies by exact model and the country where the phone was sold, so check your model and regional variant in our compatibility checker before buying.
Yes. The Wanderly Saint Martin eSIM runs as a secondary line alongside your primary SIM, so you keep calls and texts on your home number while using mobile data from the eSIM. Your home carrier may still charge for calls and texts abroad; disable data roaming and automatic data switching on the home line.
Saint Martin eSIM plans start from $1.99 on Wanderly, depending on the selected data allowance and duration. Check the available plans above for the current total price and coverage.
Most plans begin when the eSIM first connects to a supported network in Saint Martin or the covered region. Activation rules can vary, so check the instructions for your selected plan before installing or turning it on.
