What 22.3 Mbps actually means in Saint Martin

Typical download speed on Orbislo in Saint Martin: 22.3 Mbps. That is below the Caribbean median of 37.6 Mbps, so plan around it rather than being surprised by it.

The tenth percentile drops to 3.6 Mbps, a long way below the median. In practice that means Saint Martin is quick when the cell is quiet and difficult when it is not. Download your maps and your boarding passes before you need them.

Maps, messaging, ride hailing and payment apps all work without complaint. Video calls connect but will drop resolution, and streaming is better set to standard definition than left on automatic. Tethering a laptop works for email and documents rather than for calls.

Which networks you will be on

Orbislo carries traffic in Saint Martin on Orange Caraïbe, Digicel, Dauphin Telecom, Free Caraïbe and UTS. Your phone is not tied to one of them. When the network you are attached to congests or drops, the profile moves you to the other, and it happens without a prompt and without you noticing anything except that the connection kept working.

This matters more than the headline speed. Almost every travel eSIM sold today resells a single upstream agreement per country, so when that one network has a bad hour you have a bad hour with it and your only option is to buy a second eSIM from somebody else. A profile with more than one network behind it can make a decision you never see.

5G in Saint Martin: yes, standalone. Worth knowing that 5G on a travel profile is normal rather than special, and that the tenth percentile above is the number that will decide how the trip feels, not the generation label in the status bar.

A single carrier provider cannot make this move.

What data costs in Saint Martin

A 1 GB plan for Saint Martin starts at $5.89, which is $5.89 a gigabyte. That is the number to compare between providers, because a headline price attached to a different allowance tells you nothing.

The comparison most providers would rather you did not run is cost per gigabyte actually used. Independent surveys of travel data put the share of purchased data lost to expiry between 20 and 35 percent, because a plan that expires on day thirty deletes what you did not get through. Orbislo data has no expiry date, so the gigabyte you paid for is still there on the next trip. At the same headline price that is 25 to 40 percent more usable data, and in Saint Martin it means the effective cost is nearer $4.24 a gigabyte than $5.89.

Because nothing expires, the cheapest way to buy for Saint Martin is to buy slightly less than you think you need and top up if you run out. Topping up takes about ten seconds and does not involve installing anything. Buying too much is the expensive mistake everywhere else and merely a neutral one here.

Landing in Saint Martin

Install before you fly, on your home wifi. The profile downloads while you still have a connection you trust, then sits dormant until you land in Saint Martin and it attaches to Orange Caraïbe.

On landing there is one thing to check: data roaming has to be switched on for the Orbislo line. It is off by default on both iOS and Android, and it has nothing to do with roaming charges here, because the plan is prepaid and there is no bill to run up. Turn it on for the Orbislo line and leave it off for your home line, and your home number keeps working for calls and bank codes without costing anything.

What is restricted in Saint Martin

Local prepaid for residents only: Orange Caraïbe's prepaid Card offer is reserved for customers who live in the French Antilles and French Guiana. A short-stay visitor cannot count on buying the national operator's prepaid SIM over the counter on arrival.

Worth knowing about Saint Martin

The European roaming regulation does not govern roaming inside French territory. Article L.34-10 of the postal and electronic communications code extends the same rules between mainland France and the overseas territories, and Saint Martin is named on that list alongside Guadeloupe, Martinique, Saint Barthelemy, Guyane, La Reunion, Mayotte and Saint Pierre et Miquelon.
For a traveller arriving from another European Union country the collectivity counts as part of France for roam like at home, and regulators publishing the list of covered territories name Saint Martin explicitly next to Guadeloupe, Martinique, Mayotte, La Reunion and French Guiana.
The island is shared by two states. The southern half, Sint Maarten, is an autonomous country within the Kingdom of the Netherlands and one of the overseas countries and territories associated with the European Union, so crossing the island means crossing into another state.
Local operators price the Dutch side as a zone of its own. Orange Caraïbe's plans list usage from Sint Maarten separately from the French side, and texts sent from there back to the French Caribbean are charged per message rather than included.
On an Orange Caraïbe prepaid line the starting credit lasts 10 days. Once credit expires the holder has 9 months to top up and keep the number, or 3 months when topping up with amounts under 5 euros.

Questions about Saint Martin

Will my phone work in Saint Martin?

If it supports eSIM and is not carrier locked, yes. We check your exact model before you pay and tell you plainly if it will not work, rather than taking the money and leaving you to find out on arrival.

Which network will I be on in Saint Martin?

Orange Caraïbe, Digicel, Dauphin Telecom, Free Caraïbe or UTS. Orbislo moves you to whichever is performing better where you are standing, without asking you and without you noticing.

How fast is the data really?

Typical download speed is 22.3 Mbps, and 3.6 Mbps when the network is busy. The busy figure is the one to plan around: it is what you can expect when the cell is crowded.

Does the data expire?

No. There is no validity window on wallet gigabytes, and anything left over from a country pack returns to your wallet when the pack ends. This is the single largest difference between what you pay here and what you pay elsewhere.

Can I keep my normal phone number in Saint Martin?

Yes. The Orbislo profile is a second line, so your home number stays active for calls and texts on its own line. Turn data roaming off for the home line and on for Orbislo, and set up wifi calling before you fly so bank codes still reach you.

Can I tether a laptop?

Yes, on every plan, at the same allowance as your phone data and at no extra cost. At 22.3 Mbps expect a tethered laptop in Saint Martin to be fine for email and documents and strained by video calls.

What if I run out of data in Saint Martin?

Customers, meaning anyone who bought from Orbislo in the last 12 months or holds a subscription, get at least 100 MB of free rescue data once a calendar month, loaded onto the line they are using in Saint Martin when the balance runs out. It exists so you are never in the position of needing data in order to buy data. Topping up takes about ten seconds and installs nothing.

Is Orbislo cheaper than the alternatives in Saint Martin?

At $5.89 a gigabyte, the number that matters is what the data you actually use costs you. Expiry destroys 20 to 35 percent of a pack elsewhere. Ours never expires, so on cost per gigabyte used we are ahead almost everywhere.
