What Sint Maarten data actually costs
Sint Maarten travel eSIM prices look random until you convert every plan to one number: the real cost per gigabyte. Here is what that reveals right now.
The cheapest plan at each size, 30 days
| Data | Cheapest provider | Total | Price per GB | |
|---|---|---|---|---|
| 25 GB | Ubigi | $59 | $2.36/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 10 GB | Ubigi | $34 | $3.40/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
| 5 GB | Saily | $33.99 | $6.80/GB | Get plan ↗ |
| 1 GB | Ubigi | $9 | $9.00/GB | Get plan ↗🏷 10% off with code TRAVELCITY10 |
Cost per GB rises from $2.36/GB at 25 GB to $9.00/GB at 1 GB. Buying a little more data than you expect to use is almost always cheaper per gigabyte than buying exactly what you need.
The "unlimited" trap
The same words, unlimited for 30 days, cover a wide price range, and most plans slow down after a daily threshold that the label hides.
| Provider | Unlimited, 30 days | Fair-use cap | |
|---|---|---|---|
| Maya | $49.99 | Confirming | Get plan ↗🏷 10% off with code ATESIM |
| Ubigi | $108 | Confirming | Get plan ↗🏷 10% off with code TRAVELCITY10 |
Unlimited 30 day plans run from $49.99 to $108, a spread of about 116 percent, for a label that means the same thing on paper. Check the daily cap before you buy, especially if you plan to tether a laptop.
Do not overpay for coverage you will not use
If your whole trip is in Sint Maarten, a Sint Maarten only plan is far cheaper per gigabyte than a North America or global plan carrying the same data. Same provider (Saily), same 10 GB, 30 days:
| Saily plan | Price | Price per GB | |
|---|---|---|---|
| Sint Maarten only | $46.99 | $4.70/GB | Get plan ↗ |
| North America | $43.99 | $4.40/GB | Get plan ↗ |
| Global | $44.99 | $4.50/GB | Get plan ↗ |
A Sint Maarten only plan costs much less per gigabyte than a regional or global plan with the same data. Only pay for the wider plan if you are actually crossing borders on this trip.
How a Sint Maarten travel eSIM works
A travel eSIM replaces expensive roaming with a cheap local data plan you activate in seconds. There is no plastic SIM and no airport queue. Roaming with your home carrier can run 6 to 12 dollars a day, so a week easily tops 50 to 80 dollars for service you already pay for at home.
Three things to get right:
- Check your phone supports eSIM before you buy.
- Install the eSIM at home over WiFi, but wait to activate it until you land, because the validity period usually starts on activation.
- Keep your physical SIM in the phone for calls and texts on your normal number.
How we rank Sint Maarten eSIMs
Every plan on this page is sorted by real price per GB (total price divided by included data, normalised to USD), so a cheap-looking 1 GB plan cannot outrank a better-value 10 GB one. We refresh prices daily and only list providers with a track record of activating on arrival. We earn a small affiliate commission when you buy through our links. It funds the price tracking and never changes the order you see.
