Our recommendation · South AmericaOne French Guiana eSIM Pick, Sized for 7 Days (2026)
HelloRoam alone of the five takes your own currency, 31 of them. Airalo, Holafly, Nomad and Saily take dollars. French Guiana sizes to 11 GB over 7 days, which the 20 GB tier at $17.99 covers, against a list naming Orange. Airalo wins reach, 200+ destinations to 186.
French Guiana eSIM recommendation: HelloRoam. The 20GB plan at $17.99 covers a 7-day moderate trip (11GB at 1.5GB/day) on the local network your handset finds. HelloRoam pairs a 180-day refund window with support in 63 languages for French Guiana travelers.
Our recommendation
A 7-day trip to French Guiana at 1.5GB/day means 11GB of data. The 20GB plan covers that target at the lowest per-GB cost across all available tiers.
The Pick: 20GB at $17.99
#1 RecommendationThe 20GB plan costs $17.99 in the HelloRoam catalogue and connects to Orange's 5G network. Per-GB rate: $0.90/GB. That is the only per-destination price feed this site holds, so it is the only destination price we quote.
On plan shape and our published rubric, HelloRoam is the best fit of the 5 providers we score for a trip this size. Its own published entry rate is $3.50/GB, and it rates 8.7/10.
Who this plan fits
The typical French Guiana visitor who needs reliable data for navigation, social media, and messaging over 7 days without paying for unused capacity.
Why this plan
Trip-length match
1.5GB per day over 7 days totals 11GB. The 20GB plan adds 9GB of headroom beyond that target. That buffer covers photo uploads, group chats, and the occasional video call.
Per-GB value analysis
| Tier | Price | Per GB | Best for |
|---|---|---|---|
| 1GB | $1.57 | $1.57/GB | Light use (maps, email) |
| 3GB | $2.88 | $0.96/GB | Light use (maps, email) |
| 5GB | $5.68 | $1.14/GB | Moderate use (social, browsing) |
| 10GB | $9.34 | $0.93/GB | Heavy use (streaming, work) |
| 20GB Pick | $17.99 | $0.90/GB | Heavy use (streaming, work) |
Provider score breakdown
HelloRoam scores 22.3 of 25 across the 5 rubric dimensions for French Guiana. 180-day refund window on unactivated eSIMs, tied for the longest. Support in 63 languages, more than the other four combined. The main trade-off: regional multi-country bundles are not available yet.
Network routing
HelloRoam publishes one operator for French Guiana, Orange. The dataset records operator names and capability labels for French Guiana and nothing else: no throughput figure, and no statement of which operator a handset settles on. Plan the tier by trip length, not by the operator count.
Plan recommendation by usage tier
Each tier maps to a specific plan and provider for French Guiana.
Light user
Maps + messagingLight-use verdict for French Guiana: 4GB over 7 days. The 5GB plan at $5.68 ($1.14/GB) on a local 5G network covers email, maps and messaging. We pick HelloRoam for this tier because it scores 86 out of 100 on the published match formula. Limitation: no regional bundles yet, so multi-country trips need one plan per country.
Moderate user
Social + browsingModerate travelers in French Guiana (social media, navigation, browsing) use 11GB over 7 days at 1.5GB/day. HelloRoam's 20GB plan at $17.99 ($0.90/GB) covers that, and a local 5G network carries it. This is the most common traveler profile and the plan size we recommend to first-time visitors. Holafly takes the Moderate tier at 96 out of 100. The trade-off with Holafly: the absence of a per-GB tier means light travelers buy more than they need.
Heavy user
Streaming + callsIf you stream video, run a hotspot, or join two hours of video calls daily in French Guiana, budget 21GB over 7 days. The catalogue sells unlimited here at $1.82/day, which covers that without tracking. Holafly is the match-score pick at this tier, 96 out of 100. Support there is live chat and email in 10 languages, around the clock. Queue your downloads for the hotel and spend mobile data only on live traffic.
Your French Guiana trip type, matched to a plan
Weekend, vacation, business, or backpacking. Each trip profile maps to a different plan.
Weekend (2-3 days)
Weekend trip to French Guiana (2-3 days): 5GB covers moderate use (maps, social, messaging) on a local 5G network. The 5GB plan at $5.68 fits the trip. Unlimited at $5.46 for 3 days is competitive for heavy weekend use. Buy small. Unused gigabytes do not roll over, and a weekend does not need a month's data.
Vacation (7-14 days)
Vacation in French Guiana (10 days): 15GB at 1.5GB/day for social sharing, navigation, and restaurant searches. The 20GB plan at $17.99 ($0.90/GB) on a local 5G network covers the trip. Add 20% to your estimate if you plan to post daily photo sets or use camera translation.
Business (3-7 days)
Corporate travelers in French Guiana need 3GB/day across 5 days (15GB total) for conferencing, messaging, and document sync. Unlimited at $1.82/day prevents mid-meeting data cutoffs on the local network your handset finds.
Backpacking (10-30 days)
Budget backpackers in French Guiana stretch 14+ days on 0.8GB/day (12GB total). Hostel WiFi handles evening browsing and social uploads. Mobile data covers daytime maps and messaging. The 20GB plan at $17.99 on the local network your handset finds covers the trip. Unlimited at $25.48 for 14 days is overkill for light backpacker use.
Your French Guiana provider comparison
Not all providers perform equally in French Guiana. Coverage, pricing, and support quality vary by carrier routing and plan structure. Buy Airalo for a route rather than a destination. It publishes 200 destinations and the only fully published regional-bundle shape here, spanning 16 to 130 countries on one profile. The cost of that reach is the highest published floor of the five, $4.50/GB, and a refund window that shuts after 14 days. Holafly publishes unlimited daily from $2.99/day and ties HelloRoam on the longest refund window at 180 days. Heavy data users skip the arithmetic entirely. Limitation: a 1GB/day tethering cap, post-threshold throttling, and no fixed tier, so light and moderate travelers overpay. The French Guiana unlimited rate we hold, $1.82/day, is HelloRoam's own. Saily builds Nord Security VPN routing into every plan. The VPN adds cover on public WiFi at airports, hotels and cafes. Its published entry rate is $3.99/GB. Trade-off: support is email in 1 language, with no round-the-clock hours, and Saily publishes 200 destinations against Airalo's 200+. On price, Nomad leads the fixed plans: $3.00/GB published, cheaper than anyone else here. For scale, the cheapest French Guiana plan in our feed is 1GB at $1.57, a catalogue price. Best for single-country budget trips. Limitations: no unlimited option, no usage tracking, and support that is email in 2 languages, with no round-the-clock hours. Travelers who need help mid-trip should look at HelloRoam or Holafly. The argument for HelloRoam in French Guiana is recoverability. Buy the wrong size and you have 180 days on an unactivated eSIM. Hit a setup problem and support answers live chat, WhatsApp and email in 63 languages, around the clock. Its $3.50/GB floor sits above Nomad's, and it sells no regional bundle yet.
Why the rubric leader finishes first
HelloRoam tops the rubric for French Guiana at 8.7 out of 10, computed the same way for all 5. The case for it is what happens when a plan does not fit: 180 days to refund an unactivated eSIM, and support you can reach, live chat, WhatsApp and email in 63 languages, around the clock. The case against it is reach and price. Airalo covers 200 destinations and sells regional bundles HelloRoam does not. Nomad starts at $3.00/GB. Both of those are real wins and neither is ours.
Alternative options
Different traveler profiles need different plans. Here are runner-ups for each use case.
1GB at $1.57
Cheapest available plan for light users. Good for 3 to 4 day trips where you only need maps and messaging. Per-GB cost: $1.57/GB.
20GB at $17.99
Maximum data capacity at $17.99. If you stream video, share hotspot, or sync cloud files daily, this is your plan. Rate: $0.90/GB.
Unlimited at $1.82/day
Pay $1.82/day for uncapped 5G data. The 20GB plan at $17.99 is cheaper for trips under 10 days. Best for streamers and remote workers.
| Days | Price | Per day | Discount |
|---|---|---|---|
| 1 | $1.75 | $1.75/day | 4% |
| 3 | $5.02 | $1.67/day | 8% |
| 7 | $11.72 | $1.67/day | 8% |
| 14 | $22.68 | $1.62/day | 11% |

Published daily bands for a 7-day trip
| Band | GB per day | 7-day total | What it covers |
|---|---|---|---|
| Light | 0.5 | 4 GB | Maps, messaging, boarding passes |
| Moderate | 1.5 | 11 GB | The above plus social feeds and browsing |
| Heavy | 3 | 21 GB | Streaming, video calls, laptop hotspot |
HelloRoam sizes a French Guiana plan against those three bands and nothing else. A 7-day trip runs 4 GB on the light band, 11 GB on the moderate one and 21 GB on the heavy one, so the gap between the cheapest and the safest tier is 17 GB of headroom. Pick the band your phone habits already sit in at home.

Skip the generic calculator. French Guiana has specific conditions that change your data plan size. Adjusted daily estimate: 1.5GB/day (down from the 1.5GB baseline). Over 7 days: 11GB total on the local network your handset finds. The 20GB plan at $17.99 ($0.90/GB) covers this adjusted budget.

Common French Guiana eSIM questions
Direct answers to the questions travelers ask most about French Guiana eSIM plans.
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.
Best plan for 7 days?
7 days at 1.5GB/day means you need 11GB in French Guiana. The 20GB plan gives you 20GB at $17.99 ($0.90/GB) on the local network your handset finds. That is $2.57/day with 9GB to spare. Prices are the catalogue's for French Guiana.
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.
Your questions, answered
What is the best eSIM plan for French Guiana in 2026?
The 20GB plan at $17.99 on the local network your handset finds, a HelloRoam catalogue price. It covers 7 days of moderate use at $0.90/GB. 6 plans are available across 5 providers.
How do I choose between fixed and unlimited data for French Guiana?
Fixed data wins for trips under 10 days at moderate use. Unlimited at $1.82/day saves money if you use more than 3GB per day or stay longer than 10 days.
Which eSIM provider is best for French Guiana?
HelloRoam scores 22.3 of 25 for French Guiana across per-GB value, plan flexibility, buyer protection, support access, and destination reach, which is first of the five on this site's weighting. 180-day refund window on unactivated eSIMs, tied for the longest. Regional multi-country bundles are not available yet.
Can I switch plans mid-trip in French Guiana?
Yes. Buy a second eSIM through the provider app while in French Guiana. Most phones support 8+ eSIM profiles. Delete the expired plan to free a slot. You do not lose your home number.
Should I buy a French Guiana eSIM or a regional bundle?
A French Guiana-specific plan gives the best per-GB rate for single-country trips. Regional bundles only make sense if you visit 3+ countries in the same region.
How far in advance should I buy my French Guiana eSIM?
Buy 1 to 3 days before departure. Install the QR code over WiFi at home. The validity timer starts at first network connection in French Guiana, not at purchase. This gives you time to troubleshoot any installation issues before your flight.
Is the 20GB plan enough for streaming in French Guiana?
Streaming puts a traveler on the published 3 GB heavy band. Over 7 days that is 21GB. The 20GB plan falls short for daily streaming. Heavy streamers should consider 20GB or unlimited at $1.82/day.
What network does my French Guiana eSIM connect to?
HelloRoam publishes one operator for French Guiana, Orange. The published list carries the 5G capability label, and it does not record which operator a given handset selects. Save offline maps for French Guiana before you fly.
