What a Saint Martin eSIM gets you

Coverage and speed

Plans for Saint Martin run on 3G, 4G and 5G where the local network supports it. Depending on the plan you pick, you connect through 3, 7acht, A1 and AIS and 132 other networks.

17 of these also work in other countries, so one eSIM can cover a multi-stop trip rather than needing a new one at each border.

Data and validity

Allowances range from 1 GB to 20 GB, valid for 1, 7, 15, 30, 90 and 365 days. Prices start at $0.86 USD and the largest plan is $106.00 USD.

28 of the 28 can be topped up without buying a new eSIM — worth knowing if you are unsure how much data you need.

When the clock starts

Every Saint Martin plan starts counting when the eSIM first connects to a network in Saint Martin — not when you buy it and not when you install it. You can safely install on Wi-Fi at home days before you fly.

Saint Martin eSIM questions

How much does an eSIM for Saint Martin cost?

Plans start at $0.86 USD and go up to $106.00 USD, depending on how much data you need and for how long. That is the full price — there is no activation fee and nothing is added at checkout.

How much data do I need for Saint Martin?

Allowances run from 1 GB to 20 GB. Maps and messaging use very little; streaming and hotspotting a laptop use a lot. 28 of our 28 Saint Martin plans can be topped up later, so starting small is a reasonable way to find out.

When does a Saint Martin eSIM start counting?

On first connection to a network in Saint Martin — not at purchase and not at install. Install it on Wi-Fi before you travel and nothing is used up.

Can I keep my own number in Saint Martin?

Yes. The eSIM is data only and sits alongside your normal SIM, so calls and texts keep working on your usual number. Turn mobile data off for your home SIM to avoid roaming charges from your own carrier.

Which networks does it use in Saint Martin?

Depending on the plan, 3, 7acht, A1, AIS and AirTel and others. Speeds are 3G/4G/5G and 3G/4G where the local network supports it.

Will it work on my phone?

Your phone needs to support eSIM and be carrier-unlocked. Most iPhones from the XR onwards and most recent Android flagships do. A phone locked to a carrier cannot install an eSIM however new it is.
