Which network you get

Carrier	Role	5G
Orange Caraïbe	Primary, used by default	yes, standalone
SFR Caraïbe	Failover, used when the primary degrades	yes, standalone
Digicel	Failover, used when the primary degrades	yes, standalone
Free Caraïbe	Failover, used when the primary degrades	yes, standalone

You do not choose between them. If the network you are on gets congested we move you to the other one automatically, in the middle of your trip, and tell you afterwards.

A single carrier provider cannot make this move.

How we measure

Orbislo devices report connection quality on real traffic, never synthetic speed tests, because a speed test spends your data to tell us something we can measure for free. Reports carry the carrier, the radio type, the throughput and a coarse location of roughly one kilometre. No precise location is ever collected, nothing is published below a sample of 25, and you can switch the whole thing off in one tap.

Measured from real sessions, never from a speed test we ran ourselves.

What the French Guiana numbers mean

Two numbers matter and only one of them is the one every seller quotes. The median, 32.5 Mbps, is the middle of 1573 real sessions: half were faster, half were slower. It tells you what a good moment looks like.

The tenth percentile, 1.5 Mbps, is the one that matters. It is the speed in the worst tenth of the day, when the cell above the station is full and everybody around you is on it too. A country with a high median and a low floor is a country that works beautifully right up until the moment you actually need it.

None of this is a speed test. These are real sessions on real handsets belonging to travellers who left measurement switched on, aggregated over ninety days, and a country is not published at all until it has 25 of them.

What happens in French Guiana when the network is busy

Congestion is not a fault, it is a Tuesday evening. The question is what your eSIM can do about it, and for most travel eSIMs the answer is nothing: one wholesale agreement per country, one network, and no way out except buying a second eSIM from somebody else while standing in the street.

Here, Orbislo traffic runs over Orange Caraïbe, SFR Caraïbe, Digicel and Free Caraïbe. When the network you are on degrades we move you to another one, mid trip, without you asking, and tell you afterwards rather than interrupting you at the time.

Questions about French Guiana

Which network will I be on in French Guiana?

Orange Caraïbe, SFR Caraïbe, Digicel or Free Caraïbe. 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?

Median 32.5 Mbps and tenth percentile 1.5 Mbps, from 1573 real customer sessions. The tenth percentile is the number that matters: it is what you get when the cell is busy.

Can I tether a laptop?

Yes, on every plan, at the same allowance as your phone data and at no extra cost. At 32.5 Mbps expect a tethered laptop in French Guiana to be fine for email and documents and strained by video calls.

How current are these French Guiana speeds?

They are a rolling ninety day window, recalculated daily from the sessions coming in. A carrier that upgrades its network shows up here within weeks rather than at the next annual review, and a country whose sample drops below 25 stops being published rather than showing you a stale number.

What if I get no signal at all in French Guiana?

Open the app and use your free rescue data: 100 MB a month, on every account, in over 200 countries, and it works at a zero balance. It exists for exactly this moment, because needing data in order to buy data is not a situation anybody should be put in. If that cannot find a network either, message us from the app and we will sort it.

Will my phone work in French Guiana?

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.
