Coverage & network in Saint Martin
The plans for Saint Martin are regional: one eSIM that covers Saint Martin alongside its neighbours, which is exactly what most trips through this part of the world look like. Every plan shown here works in Saint Martin — the coverage counter on each one tells you where else it reaches.
Plan sizes on this page run from short-stay allowances to remote-work territory. Count 100–200 MB a day for maps and messaging, and 1 GB an hour once video is involved.
Coverage in Saint Martin is 4G/LTE. It handles navigation, messaging, calls over data and streaming without complaint, and it reaches considerably further than any 5G rollout currently does. Tethering is allowed on every Saint Martin plan, so a laptop or a travelling companion can share the connection.
Because these are regional plans, crossing into a neighbouring country usually needs no new eSIM at all — check the coverage list on the plan you pick. The full Caribbean plan page shows everything the region offers, and Dominican Republic, Grenada and Guadeloupe have their own pages too.
How to install it

- 3

Turn on data roaming for the TravelNet line when you arrive. The plan starts counting down on that first connection, not at checkout.
Will my phone work?
You need an eSIM-capable, carrier-unlocked phone: an iPhone XS or newer, a Pixel 3 or
newer, or a recent Samsung Galaxy S, Z or A-series flagship. Dial *#06# — if
an EID number is listed alongside the IMEI, the phone has an eSIM.

Saint Martin eSIM questions
Which network does the Saint Martin eSIM use?
We don't publish a single operator name for Saint Martin, because the profile can attach to more than one partner network and picks whichever is strongest where you are. In practice that means you get the best available signal rather than being locked to one operator's weak spots.
Will I get 5G in Saint Martin?
No. Saint Martin plans run on 4G/LTE, which is what the networks cover reliably. For maps, messaging, calls over data and streaming the difference is not something you'll notice.
How much data do I actually need for Saint Martin?
Count on 100–200 MB a day if you're mostly using maps and messaging, and 1 GB an hour once video is involved. Pick the plan one size up from your estimate — running out abroad costs more hassle than the size difference.
When does my Saint Martin plan start counting down?
When the eSIM first connects to a network in Saint Martin, not when you buy it. Install it at home a day or two before you fly — the validity period on the plan you choose runs from arrival, not from checkout.
Why do Saint Martin plans list other countries too?
Because they are regional eSIMs: one profile whose allowance works across every country on its coverage list, Saint Martin included. For a single-country trip nothing changes — install, land, connect. For a multi-country trip it means the same plan keeps working after the border.
Can I use my Saint Martin eSIM as a hotspot?
Yes. Tethering is enabled on every Saint Martin plan, so you can share the connection with a laptop, a tablet or someone travelling with you. Hotspot data comes out of the same allowance.
Can I keep my own phone number while I'm in Saint Martin?
Yes. Nothing is removed from your phone. The Saint Martin profile is added as a second line and set as the one used for data, while your usual number keeps receiving calls, texts and bank verification codes. Switch data roaming off on the home line before you fly.
Do I need to register or show a passport to use a Saint Martin eSIM?
No. The plan roams on partner networks, so there's no local SIM registration, no ID upload and no shop visit. You buy it, scan the QR code, and it works on arrival.
What happens if I run out of data in Saint Martin?
You can buy another Saint Martin plan from the same page and install it the same way. Plans marked as top-up capable can also be extended without a new QR code.
I'm also visiting Dominican Republic and Grenada — do I need separate eSIMs?
Check the coverage list on the plan you pick first — many Saint Martin plans are regional and already include the neighbours, in which case one eSIM covers the whole trip. Otherwise the Caribbean plan does.
Will my phone work with a Saint Martin eSIM?
If it's an iPhone XS or newer, a Pixel 3 or newer, or a recent Samsung Galaxy S, Z or A-series flagship, almost certainly — and it must be carrier-unlocked. Dial *#06# and look for an EID number: if one is listed, the phone has an eSIM. Our compatibility list has the full set.
