Customer reviews
My travel eSIM connected to 5G as soon as I landed in Rome — no need to search for a local SIM card kiosk. I had fast 5G across central Rome, and even in the smaller Tuscan hill towns where coverage switched to 4G, Google Maps and WhatsApp calls stayed smooth and reliable.
Why buy an Atli eSIM for St. Martin
No roaming bill to open when you land
You pay for the data plan before you travel, at a price you can see. International roaming charges from your home carrier do not apply to an Atli eSIM.
Buy on the site or in the chat
Pick a plan here, or in Telegram or WhatsApp — the same plans at the same prices. There is no travel eSIM app to download, and no account to create unless you want one.
Your own number keeps working
An eSIM is a second line. Your physical SIM stays in the phone, so calls and messages on your normal number still arrive while data runs on the Atli eSIM.
Top up without buying again
If the data runs out mid-trip, add more to the same eSIM in the chat. You do not install a new profile or start over.

What the plan covers
An Atli eSIM for St. Martin runs on local 4G and 5G partner networks, the same masts a domestic SIM uses. Coverage follows those networks, so it is strongest in cities and along main routes.
Atli eSIM , a local SIM card or roaming in St. Martin?
The three ways to get data abroad, and what each one asks of you.
| The three ways to get data abroad, and what each one asks of you. | Atli eSIM | Local SIM card | Roaming |
|---|---|---|---|
| Set up before you travel | Yes | No | Yes |
| No roaming charges | Yes | Yes | No |
| Keep your own number | Yes | No | Yes |
| Price fixed before you go | Yes | No | No |
| No shop, no paperwork | Yes | No | Yes |
| Top up from the chat | Yes | No | No |
Roaming keeps your number and needs no setup, but the price is your carrier's and you only see it on the bill. A local SIM is cheap and needs a shop, your passport and a swapped-out card.
Will my phone work with an eSIM in St. Martin ?
An eSIM needs a phone that supports one and is not locked to a single carrier. Most phones released since 2018 qualify: iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and recent Motorola, Huawei, Oppo and Xiaomi models.
Two things to check before you travel. Dial *#06# — if the screen shows an EID number, the phone supports eSIM. And a phone bought on a carrier contract may be locked; your carrier can unlock it, usually for free once the contract is paid.

Questions about eSIM in St. Martin
How much does an eSIM for St. Martin cost?
Atli eSIM data plans covering St. Martin start at $3.99. What you pay depends on how much prepaid data you want and how long you are travelling. You see the full amount before paying — nothing is added at checkout, and there is no monthly charge afterwards.
When should I buy and install my St. Martin eSIM?
Buy before you leave and install while you still have Wi-Fi, then leave the line switched off until you land. Installing the eSIM profile needs an internet connection; using the data plan in St. Martin does not.
Which phones work with an Atli eSIM?
Any eSIM-compatible phone that is not carrier-locked: iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus recent Motorola, Huawei, Oppo and Xiaomi models. Dial *#06# — if an EID number appears, your phone supports eSIM.
Do I keep my own phone number in St. Martin?
Yes. An Atli eSIM is a second line alongside your physical SIM, so your usual number stays active for calls and SMS. Set the Atli line as your data line and your home line for calls, and nothing on your normal number changes.
How do I activate the eSIM when I land in St. Martin?
Scan the QR code Atli sends you in the chat, then switch the Atli line on under Settings → Mobile data and turn on data roaming for that line only. It connects to a local 4G/5G partner network, usually within a minute of landing.
What happens when my data runs out?
The connection stops rather than continuing at a price you did not agree to — there are no overage charges and no bill afterwards. Top up the same eSIM in the chat and carry on, without installing a new profile.
Can one eSIM cover more than one country?
A country plan works in that country. If your trip crosses borders, a regional eSIM plan — Europe, Asia, Latin America and more — covers every country in the bundle on a single eSIM, so the data keeps running at the border.
Can I share my St. Martin data with another device?
Yes. Turn on your phone's personal hotspot and a second phone, tablet or laptop uses the same data plan, exactly as it would at home. No second eSIM and no extra charge.
