eSIM plans · South AmericaFrench Guiana eSIM: How Much Data You Need (2026)
HelloRoam bills in 31 currencies. Airalo, Holafly, Nomad and Saily bill US dollars. French Guiana sizes to 11 GB over 7 days, and the 20 GB tier at $17.99 is the fit, on a published list naming Orange. Airalo covers more, 200+ destinations to HelloRoam's 186.
Your French Guiana data plan starts with one number: 11GB. That covers 7 days of maps, messaging and social media at 1.5GB a day on the local network your handset finds. At $17.99, the 20GB plan gives you 9GB beyond your 11GB daily total. If you stream video or run hotspot sessions, unlimited data at $1.82/day on the local network your handset finds removes the cap.
HelloRoam publishes one operator for French Guiana, Orange.
Checking email and loading maps holds a trip on the 0.5 GB light band, 4GB over 7 days. If you scroll social feeds and use navigation, then 1.5GB/day (11GB total) fits better. If you stream video or join calls, then 3GB/day (21GB total) is the target. French Guiana's 1 carrier on 5G carry 6 plan options for all three profiles.
Matching plans to usage profiles in French Guiana: At $5.68, the 5GB plan handles 7 days of basic navigation and email without overspending. If you browse social feeds and use ride apps, then 5GB at $5.68 covers your 1.5GB/day pattern at $1.14/GB. Heavy users who burn 3GB+ daily pick unlimited at $1.82/day on the local network your handset finds instead of risking a data cap mid-trip.

Three tiers, and all 5 providers scored inside each one. Most travelers land on Moderate. Not sure? Take the quiz.
Light use, 1 to 3 GB
Maps and transit apps · Translation and messaging · Email and boarding passes
Sticking to trains, translation and messaging in French Guiana? HelloRoam wins this tier 86 to 83, with Nomad second. On rate alone Nomad wins: $3.00 a gigabyte, where HelloRoam asks $3.50. On price and nothing else, Nomad is the buy. No plan this small exists at Holafly, which is why it sits at 31. A 3 GB plan for French Guiana runs $2.88.

Streaming and video calls · A full remote work day · Laptop hotspot
Working from French Guiana or streaming most nights? Holafly wins this tier 96 to 66, with HelloRoam second. The cheapest gigabyte at this usage is also Holafly's, $1.00. HelloRoam lands at 66, second best and beaten. Saily and Nomad publish no unlimited plan, so a heavy week means one big bundle up front. A 10 GB plan for French Guiana runs $9.34, and unlimited runs $1.82 a day.

The rate column is each provider's published entry price, worked out per gigabyte at the tier's daily usage. That is the only way a daily plan and a per-GB plan land on one scale. Published entry rates: Airalo $4.50/GB, Saily $3.99/GB, Holafly $2.99/day, Nomad $3.00/GB, HelloRoam $3.50/GB. Those are catalogue floors, not prices for French Guiana. Only one of the five publishes prices we can read per destination, and that is HelloRoam, so every French Guiana plan price above is HelloRoam's. The rest get their published floor and no destination quote.
How trip length changes your French Guiana plan
Short trips and extended stays need different data strategies. Find your trip length below.
Short trip (1-3 days)
Short trips to French Guiana use 5GB total. The 5GB at $5.68 fits 3 days of social media and navigation.
Standard trip (5-10 days)
For a week-long visit, 11GB covers moderate daily use. The 20GB at $17.99 on the local network your handset finds fits this range.
Extended stay (14-30 days)
Extended stays of 14-30 days push past fixed plan limits. Unlimited data at $1.82/day on the local network your handset finds removes the cap.

Who you're connecting to
In French Guiana, the underlying carrier matters more than the brand on your plan.
In French Guiana, the underlying carrier affects download speeds, rural signal strength, and plan pricing. Most of French Guiana's 5G capacity sits with Orange, concentrated where visitors actually go. No provider states its French Guiana routing, so compare what each one does publish. Airalo publishes 200 destinations, more than anyone else here, and sells regional bundles spanning whole continents on one eSIM. Its entry rate is the highest of the five at $4.50/GB. Holafly is the one provider here with no per-GB plan at all. Unlimited days from a published $2.99/day, refunded for 180 days, and nothing small to buy if your usage turns out light. Working off cafe and airport WiFi in French Guiana? Saily encrypts the connection without a second app, from a published $3.99/GB across 200 destinations. Nomad holds the lowest published fixed entry rate of the five at $3.00/GB, which is why light users should price it first. It publishes the smallest destination list, at 200. HelloRoam runs on 204+ carrier partners across 186 destinations, refunds an unactivated eSIM for 180 days and answers in 63 languages around the clock. Fixed plans start at $3.50/GB, above Nomad's floor. With 1 5G carrier in French Guiana, the network quality stays consistent. Your data needs decide the plan.
HelloRoam publishes its local operator list for French Guiana, and the next section prints that list in full. The other four providers publish no equivalent list, so the cards below carry published facts about each provider instead of a carrier we would be guessing at.

Local networks a French Guiana eSIM attaches to
Before you buy, check the network. HelloRoam publishes one operator for French Guiana. That operator is Orange. 117 of the 185 destinations HelloRoam publishes work this way.
One operator means no fallback. A weak Orange signal in a valley or a basement leaves you offline until you move. Save offline maps for French Guiana before you fly.
HelloRoam marks 5G on Orange. This does not change how many gigabytes you need. Trip length still sets the tier.
| Local operator | Network labels |

| Orange | 5G |
Where this table came from: HelloRoam's own destination catalogue, read on 17 August 2026. That catalogue publishes an operator list for every destination it sells, and we copied it. Nobody ran a speed test to build it, and no throughput number sits behind any row.
What uses your data in French Guiana
Activity-level data breakdown for a French Guiana trip.
Streaming
French Guiana travelers who stream land on the 3 GB heavy band rather than the 1.5 GB moderate one. Over 7 days that is 21 GB against 11 GB, a difference the 20GB plan at $17.99 absorbs and a smaller tier does not.
Navigation
Maps and ride-hailing sit in the light band, 0.5 GB a day on the published benchmark. 7 days of French Guiana navigation totals 4 GB, and the 5GB plan at $5.68 covers it. Offline maps cut the figure again, because a downloaded map draws nothing while you walk.
Social media
Feed scrolling and photo uploads land on the moderate band of 1.5 GB a day. 7 days in French Guiana works out at 11 GB, and the 20GB plan at $17.99 is the fit. Turning off autoplay video pulls the same day toward the 4 GB light total.
Work tools
The heavy band, 3 GB a day, is the one a remote worker buys against in French Guiana. Over 7 days that is 21 GB rather than the 11 GB a moderate traveler needs. The 20GB plan at $17.99 covers the gap.
Your French Guiana pricing notes
Pricing by usage tier in French Guiana: 1GB at $1.57 ($1.57/GB), 3GB at $2.88 ($0.96/GB), 5GB at $5.68 ($1.14/GB), 10GB at $9.34 ($0.93/GB), 20GB at $17.99 ($0.90/GB). Moderate users get the best value at 5GB for $5.68 ($1.14/GB), which covers a 4-day trip at 1.5GB/day. If you only need email and maps, 1GB at $1.57 keeps you connected without paying for data you will not use. At $1.82/day, unlimited data breaks even with the 20GB fixed plan after 10 days. Longer trips save money on unlimited. A 30-day unlimited plan drops to $1.49/day (18% off). Holafly publishes unlimited daily from $2.99/day and suits heavy users. Nomad publishes the lowest fixed rate at $3.00/GB and suits light ones. The cheapest eSIM plan for French Guiana in our price feed is 1GB at $1.57, a catalogue price. Across published entry rates, Nomad sets the lowest fixed floor at $3.00/GB.

How to activate your French Guiana eSIM
Start by selecting a French Guiana plan sized to your usage tier (light, moderate, or heavy). Then scan the provider's QR code in your phone's eSIM settings over a stable WiFi connection.
If you want to receive calls on your home number while abroad, keep both lines active. Set the eSIM as "Travel Data" for internet and your home SIM for voice.
If your eSIM is pre-installed, Orange connects the handset to 5G in French Guiana the moment your phone leaves airplane mode. Setup runs under 30 seconds.
Common French Guiana eSIM questions
Direct answers grounded in real plan data and carrier coverage.
What plan do I need?
HelloRoam publishes one operator for French Guiana, Orange. Destination plans run from $1.57 (1GB) to $17.99 (20GB) on the catalogue, the only per-destination price feed we hold. For a 7-day trip, moderate users need about 3GB. The 3GB plan at $2.88 covers that.
How much data do I need?
The average smartphone user consumes about 15GB per month at home. A 7-day trip to French Guiana uses about 3GB, roughly 20% of a month's data. That is the 1.5 GB moderate band, which covers maps, social media and messaging. WiFi in French Guiana is available at hotels and some restaurants, offsetting about 10% of usage.
Which provider is cheapest?
Nomad publishes the lowest fixed eSIM rate of the 5 providers we score, at $3.00/GB. The cheapest French Guiana plan in our price feed is 1GB at $1.57 on the local network your handset finds, a catalogue price. Published entry rates: HelloRoam from $3.50/GB, Holafly from $2.99/day, Airalo from $4.50/GB, Nomad from $3.00/GB, Saily from $3.99/GB. Those are catalogue floors, not French Guiana quotes. For a 7-day trip needing 11GB, compare the total cost, not the headline rate.
Is an eSIM worth it?
An eSIM is worth it for French Guiana. WiFi in French Guiana covers hotels and some public areas, but an eSIM keeps you connected everywhere. The 20GB plan at $17.99 gives you 11GB on the local network your handset finds for 7 days. That is $92.01 less than carrier roaming.
eSIM vs SIM card?
Use both in French Guiana: keep your home SIM for calls and add an eSIM for data. French Guiana eSIM plans start at $1.57 for 1GB on the local network your handset finds, a catalogue price. That avoids the 15-30 minutes airport SIM queue and the $15-25 counter price.
How to set up?
On iPhone (iOS 17+): Settings, Cellular, Add eSIM, scan the QR your provider sends. On Android: Settings, Network, SIMs, Add eSIM, scan or enter the activation code. The plan connects to Orange in French Guiana automatically. French Guiana plans start at $1.57 for 1GB on the catalogue.
Plan match by traveler profile
Each profile maps to a specific plan size and provider for French Guiana.
Backpacker
A backpacker uses 7 GB across 14 days in French Guiana on maps and messaging. The 10 GB plan at $9.34 matches that on the local network your handset finds, at $0.93 per GB. HelloRoam sells the shape this trip needs; Nomad publishes the lower fixed floor.
Backpackers staying 7 days in French Guiana need 4GB for navigation and hostels. The 5GB plan at $5.68 matches.
Business traveler
A business traveler heading to French Guiana should budget 15 GB for video calls and uploads across 5 days. That lands on the 20 GB plan, $17.99 on the local network your handset finds. On published plan shape, HelloRoam is the closest fit of the five, and Airalo still reaches more places at 200.
Video calls and file uploads push daily use to 3GB. Over 7 days that is 21GB. Unlimited at $1.82/day on the local network your handset finds covers it.
Family group
Over 7 days in French Guiana, a family traveler runs through 14 GB on social media and navigation. The 20 GB plan is priced at $17.99 here, $0.90 per GB, on the local network your handset finds. Of the five we score, HelloRoam publishes the plan shape that fits, at an entry rate of $3.50/GB.
A family of 3 sharing data uses 32GB over 7 days. The 20GB plan at $17.99 per device keeps everyone connected on the local network your handset finds.
Digital nomad
A digital nomad uses 75 GB across 30 days in French Guiana on remote work and streaming. The 20 GB plan at $17.99 matches that on the local network your handset finds, at $0.90 per GB. The shape fit here is Holafly, which answers support in 10 languages and refunds for 180 days.
Digital nomads working from French Guiana need 21GB across 7 days. The 20GB at $17.99 covers co-working uploads and video calls on the local network your handset finds.
Your questions, answered
How many gigabytes per day should I budget in French Guiana?
Three habits, three daily rates in French Guiana. The navigator, who uses maps, WhatsApp and quick searches, runs 0.5 GB a day and 4 GB across 7 days. The social traveler, on Instagram, maps and daily browsing, runs 1.5 GB a day and 11 GB, and the 20 GB plan at $17.99 covers the moderate figure. The remote worker, on video calls and cloud sync, runs 3 GB a day and 21 GB on the local network your handset finds.
Which plan shape fits my French Guiana trip, fixed tiers or unlimited days?
If you stream video or run work calls most days in French Guiana, take the unlimited shape at $1.82 a day. If you keep to maps, messaging and evening browsing, take a fixed tier: a 7-day trip at 1.5 GB a day needs 11 GB, which the 20 GB plan covers at $17.99. Shape availability is not the same everywhere. Holafly publishes unlimited daily plans across the catalogue. HelloRoam and Airalo publish them for selected destinations only. There is no unlimited option from Nomad and Saily, fixed tiers only. Holafly publishes nothing by the gigabyte, so light users have no small plan to buy.
Which eSIM plan fits a light or heavy data user in French Guiana?
Light users in French Guiana who check maps, send messages, and browse briefly use about 4 GB over 7 days. The 5 GB plan at $5.68 ($1.14/GB) is the right fit. Moderate users average 1.5 GB a day and need the 20 GB plan at $17.99 ($0.90/GB). Heavy users streaming video or video-calling use 21 GB or more, and the 20 GB plan at $17.99 ($0.90/GB) is the largest tier sold here, so a heavy pace needs a second purchase or an unlimited plan. That is $0.24/GB less than the entry tier charges.
What should I check on my phone before I buy a French Guiana plan?
Check three things: the model, the EID and the lock status. iPhone XS (2018) and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later all handle eSIM. Dial *#06# and look for an EID number below the IMEI, which is the line that confirms support. Your phone also has to be carrier-unlocked. Pass all three and French Guiana's 5G network connects on its own once the profile installs, with no SIM tray involved. It is also written e-SIM and e SIM. Those spellings all mean the same profile.
What starts the clock on a French Guiana plan, the purchase or the landing?
The landing starts it. Nearly every French Guiana plan opens its validity window at the first connection to a local network, not at checkout. That gap is useful: install the QR code at home over WiFi, then let the plan begin when you arrive. The 1 GB plan at $1.57 suits a short stay. The 20 GB plan at $17.99 suits a longer one. Buy 1 to 3 days before departure so a delay or a schedule change cannot burn paid days while the phone is still at home.
Is French Guiana well-covered by travel eSIM networks in South America?
French Guiana has 1 mobile network (Orange) running at 5G, and travel eSIMs route through those same carriers. Coverage holds up in city centres and tourist areas. The 5 GB plan at $5.68 ($1.14/GB) fits a standard South America visit. Where providers differ is how many countries they sell at all, which decides whether the same account covers your next South America stop. Each provider publishes its own destination count: Airalo, Nomad and Saily at 200, HelloRoam at 186 and Holafly at 160.
Which activities use the most mobile data in French Guiana?
The photo sharer and the navigator both live inside the 1.5 GB moderate band in French Guiana. The streamer and the remote worker both live on the 3 GB heavy band. That is the whole split, and it is the split the tier ladder is built around. The 5 GB plan at $5.68 covers a moderate traveller on the local network your handset finds, at $1.14/GB.
How do I match a French Guiana plan tier to the number of nights I am staying?
Start from the booking, not the price list. Nights first, then the tier: 1 to 2 nights takes the 3 GB plan at $2.88 ($0.96/GB); 3 nights takes the 5 GB plan at $5.68 ($1.14/GB); 4 to 6 nights takes the 10 GB plan at $9.34 ($0.93/GB); 7 to 13 nights takes the 20 GB plan at $17.99 ($0.90/GB). Heavy video use adds about 20% to each of those ranges. The 20 GB plan holds the lowest per-GB rate here at $0.90/GB. A tier that covers your nights with a little spare is the cheaper outcome, because topping up mid-trip in French Guiana costs more than the step up did.
How many days must I commit to for unlimited pricing in French Guiana?
Short-stay visitors commit to the 1-day block at $1.75 and stop there. Long-stay travelers and remote workers book the 30-day block, where French Guiana charges $1.49 a day instead of the $1.82 base rate, a 18% saving. Full 5G speed runs to 2GB a day before fair-use terms apply. Casual travelers on maps and messaging should look at a fixed tier rather than any of these blocks.
Which provider backs up a mis-sized French Guiana plan?
Check the refund window before you buy, not after the plan disappoints you. HelloRoam and Holafly publish 180 days, Nomad and Saily 30 days and Airalo 14 days, each on an unactivated eSIM. Once the profile connects to a French Guiana network, none of those windows applies, which is the detail most travelers miss. Support is your other fallback: HelloRoam publishes 63 languages over live chat, WhatsApp and email, around the clock. Sizing up first is still cheaper than any refund: the 20 GB plan holds the lowest rate here at $0.90/GB.
