Buy an eSIM for Saint Martin before you fly

Ahlano offers 17 prepaid data plans for Saint Martin, starting from USD 1.14. You pick a plan, pay by card or Apple Pay, and receive a QR code or a one-tap install link. Most travellers buy a day or two before the trip, but you can also buy after you land if you have Wi-Fi at the airport or hotel.

Each plan has a set data amount and a validity in days. An unlimited plan is also on sale for travellers who stream, share photos or work on the go.

Will my phone work in Saint Martin?

Your phone will work with an Ahlano eSIM if it meets two conditions: it must be an eSIM-compatible phone, and it must be unlocked. Recent iPhone models and many Android phones support eSIM. If you are not sure about your model, check the list of phones that support eSIM before you buy.

Your usual SIM can stay in the phone. You simply switch mobile data to the eSIM while you travel, so your home number remains on the device.

Which eSIM plan suits your trip to Saint Martin?

The right plan depends on how long you stay and how you use your phone:

• Short stays: a small plan covers maps, messages and booking a taxi.
• A week or two: a mid-size plan leaves room for photos, video calls and social media.
• Longer trips or heavy use: choose up to 20 GB with 30 days of validity, or the unlimited plan.

For example, a 2 GB plan valid for 15 days fits a relaxed beach holiday. If you run low, you can check the data left and top up.

3. Follow the steps on screen to add the eSIM.

Saint Martin eSIM FAQs

Which eSIM plan should I choose for Saint Martin?

Match the plan to your stay and your usage. Data plans range up to 20 GB with validity from 1 to 30 days, and an unlimited plan is also on sale. Light users can pick a small plan and top up later if needed.

Will my phone work in Saint Martin with an eSIM?

Yes, if your phone supports eSIM and is unlocked. Many iPhone and Android models support eSIM. Check your model before buying so the install goes smoothly.

What is the downside of an eSIM?

The main limit is the phone itself: it must be eSIM-compatible and unlocked, so some older or carrier-locked phones cannot use one. You also need an internet connection to install it, so it helps to do it on Wi-Fi before you travel.

Can I top up my Saint Martin eSIM if I run out of data?

Yes. You can check how much data is left and top up when you need more. This lets you start with a smaller plan and add data only if your trip calls for it.
