If you've already decided to buy data and the only thing left is to know how many GB for French Polynesia, this article is about that and nothing more. I'll give you the number in the first block and then explain why this particular destination moves the needle more than people imagine: there's a warning about the European rate that catches almost everyone off guard, resort Wi-Fi that doesn't always deliver, and flights between archipelagos and atolls where your phone goes completely silent.
How many GB you need: the straight answer
For 10 days in French Polynesia, most people will be fine with 5 GB. If you only use maps and WhatsApp, 3 GB will suffice; if you upload photos and videos daily, go for 10 GB; and for two or three weeks with island hopping, 10-15 GB is the comfortable range.
This figure surprises many people because French Polynesia is a long, expensive trip of two or three weeks, and one assumes that a long trip requires a huge package. Well, not necessarily. What happens in practice is that much of the day you spend in places where you neither want nor can look at your phone: on a boat, diving, on an inter-island flight, on an excursion to a motu. The hours of actual consumption are less than you think.
What does inflate the number here are three very specific things: uploading photos and videos (the destination is a content-generating machine), accommodation Wi-Fi failing and you having to rely on your own data, and remote work if you bring work with you. If none of that applies to you, your package will be small, and that's perfectly fine.
If you want the general criteria for any destination and not just this one, I have it broken down in the guide on how much data you need for travel. Here I'll delve into the Polynesian specifics, which is where the real juice is.
It's France, but your European plan doesn't work here (and this changes the calculation)
This is the warning that justifies half the guide, so I'm giving it its own section. French Polynesia is an overseas collectivity of France: the CFP franc is used, French is spoken, and the tricolor flag flies on official buildings. The question naturally arises: "If it's France, don't I have my plan included like in the Canary Islands?" No.
The European "roaming like at home" regulation applies in the EU and in the outermost regions (ORs): Guadeloupe, Martinique, Reunion, French Guiana, Mayotte, Canary Islands, Azores, or Madeira. French Polynesia is not an OR, but an overseas country and territory (OCT/PTOM), a figure with political ties to the EU but that falls outside the territory where this regulation applies. The direct consequence: here your operator will charge you international rates, which in Pacific destinations are usually among the most expensive there are.
That's why the approach changes compared to the French Caribbean. In Martinique, you could arrive and not buy anything. Here, not buying data means either paying outrageous rates or going without Wi-Fi for two weeks. This is why this article exists: since you're going to buy a package anyway, it's best to get the size right.
- Guadeloupe, Martinique, Reunion: ORs, your European plan works.
- French Polynesia, New Caledonia, Wallis and Futuna: OCTs, it does not work.
- Always check your operator's terms and conditions before landing, not after.
If what you want is to compare connection options (local SIM, Wi-Fi, digital SIM) instead of deciding on gigabytes, you can find that in internet in French Polynesia, and if the digital format sounds like Greek to you, I'll explain it in what an eSIM is.
How much data each app actually uses
Before choosing a package, it's good to have real numbers in front of you, because intuition is very misleading: people think WhatsApp devours data (false) and that photos don't use much (very false). This is the table I use, with approximate figures rounded up to be on the safe side.
| Activity | Approximate consumption |
|---|---|
| WhatsApp: messages, audio and some photos | 10-20 MB per day |
| WhatsApp video call | 350-450 MB per hour |
| Work video call (Meet, Zoom, Teams) | 600-1,200 MB per hour |
| Google Maps navigating without downloaded map | 5-10 MB per hour (+50-100 MB for initial area load) |
| Offline downloaded maps | 0 MB on the ground |
| Instagram or Facebook: feed and stories | 500-720 MB per hour |
| TikTok or full-screen reels | 800-1,200 MB per hour |
| YouTube at 480p / 720p / 1080p | 250 / 600 / 1,000-1,500 MB per hour |
| Upload 100 photos from phone to cloud | 400-500 MB |
| Upload a 1-minute video recorded in 4K | 300-400 MB |
| Streaming music, normal quality | 40-70 MB per hour |
| Email, looking for restaurants, checking schedules | 20-40 MB per hour |
| Translator with camera, per query | 2-5 MB |
The quick takeaway: messaging and maps are background noise, video is what consumes everything. A single 4K video uploaded to Instagram is equivalent to entire weeks of WhatsApp. You can find the extended breakdown in the mobile data usage statistics by activity. And yes, in Polynesia, French is ubiquitous on menus and signs, but the translator uses so little data that you don't even need to factor it into the equation.
Recommendation by profile and travel days
This is the article's table. Find your profile, cross-reference it with the number of days you're staying, and you'll have the figure. I've included the "diving and video" profile because in Tuamotu it's the most common and the one that goes furthest beyond the calculation.
| Profile | 5 days | 10 days | 15 days | 30 days |
|---|---|---|---|---|
| Maps and WhatsApp, little else | 1-2 GB | 3 GB | 3-5 GB | 8 GB |
| Daily photos and social media | 3 GB | 5-6 GB | 10 GB | 20 GB |
| Honeymoon with unreliable resort Wi-Fi | 3 GB | 5 GB | 8-10 GB | 15 GB |
| Diving and video (uploads clips daily) | 5 GB | 10 GB | 15-20 GB | 30 GB |
| Digital nomad / remote work | 10 GB | 20 GB | 30 GB | 50 GB or more |
| Family sharing one phone | 5 GB | 10 GB | 15-20 GB | 30-40 GB |
Three nuances for a good reading. First: if you're going to have decent Wi-Fi at your accommodation, step down a notch, because you'll do backups and large uploads there. Second: if two of you are traveling and only one buys data to share via hotspot, choose the "family" profile, not the individual one. Third: on a three-week trip through several archipelagos, boat and flight days consume almost zero, so 15 days of travel does not equal 15 days of intensive use.
The specific package for the destination, with its sizes and validity days, can be found on the eSIM for French Polynesia page.
Honeymoon in Bora Bora and Moorea: bungalow Wi-Fi is not a plan
Here's the honest truth almost no one tells you when you book an overwater bungalow. Wi-Fi in Polynesian resorts is very inconsistent: in some, it's free but slow, in others it works well in common areas (pool, restaurant, reception) and is weak inside the bungalow, and in some cases, "premium" or higher-speed connections are charged separately. This is logical: these are remote islands with limited infrastructure and dozens of guests trying to upload videos of the same sunset at the same time.
Booking an 800-euro-a-night bungalow doesn't guarantee 800-euro-a-night Wi-Fi. Assume that the Wi-Fi will be enough for checking emails, not for uploading a 4K sunrise video.
The practical consequence for your gigabytes is direct: don't count your accommodation as an unlimited data source. If your mental plan was "I'll buy 3 GB and do the rest via Wi-Fi," upgrade to 5 GB for ten days and sleep soundly. The price difference between those two packages is negligible compared to what you've already spent on the trip.
One more note for honeymoons: many people want the exact opposite, to truly disconnect. If that's your case, go ahead, get the small package. But keep in mind that in Polynesia, your phone is also useful for non-frivolous things: confirming transfers that change times, notifying the hotel that an inter-island flight has been delayed, or showing the QR code for an excursion. For that, 3 GB well managed is more than enough.
Island hopping: what you use between flights, ferries, and waiting times
A typical trip here links Tahiti, Moorea, Bora Bora, and sometimes Huahine, Raiatea, or a jump to Tuamotu. That means several inter-island flights, one or two ferries, and many hours at small airports. Each segment has its own consumption pattern and it's worth understanding it because it explains why the final figure is lower than expected.
- In the air: airplane mode, zero consumption. Inter-island flights are short, but they add up.
- On the Tahiti-Moorea ferry: there's coverage almost the entire trip due to the proximity of the coast; half an hour of social media can be 300-400 MB if you're not careful.
- Waiting in airports: this is the time of greatest risk for data usage. Boredom plus decent 4G equals endless scrolling.
- On boat transfers to the motus: intermittent signal, minimal consumption.
My practical advice: waiting times are where your gigabytes disappear without you noticing, not excursions. Download a couple of series or a music playlist before leaving home and you'll save several gigabytes over the course of the trip. It's also worth having your boarding passes downloaded to your phone's wallet, because at some small airports the connection is weak and you don't want to rely on a website loading to board.
And a logistical note: if you're making several jumps, check that your package covers the entire territory and not just the main island. The archipelagos are hundreds of kilometers apart, but administratively they are the same destination.
Tuamotu: Rangiroa, Fakarava, and the diving video
The atolls are where coverage and consumption behave most differently from the rest of the country. The rule is simple: there is signal in the villages and little or none outside them. In Rangiroa, the two inhabited areas, Avatoru and Tiputa, have 4G; as soon as you move away into the lagoon or towards uninhabited areas of the atoll, forget about it. In Fakarava, the village of Rotoava has limited signal, and the south of the atoll, where some of the most famous dives are, has no coverage. Vini is the operator with real presence in the outer islands; others concentrate on Tahiti and Moorea.
| Island or area | Typical coverage | Effect on your consumption |
|---|---|---|
| Tahiti (Papeete and west coast) | Good, stable 4G | High: where you'll spend the most |
| Moorea | Good in villages and coastal road | Medium |
| Bora Bora | Good on the island and in motus with resorts, variable | Medium-high if Wi-Fi fails |
| Huahine, Raiatea, Taha'a | Decent in population centers | Low |
| Rangiroa | 4G in Avatoru and Tiputa; none outside | Low, intermittent |
| Fakarava | Limited in Rotoava; south without coverage | Very low |
| Marquesas and remote atolls | Scarce or non-existent | Almost zero |
Now the trap: diving fills your memory with video and then you want to upload it all. You return to the village with fifteen clips of grey sharks, and as soon as you get 4G, your phone starts syncing. A day of diving recorded in 4K can easily amount to 3-5 GB of upload. If you're going to dive with a camera, set automatic backup to Wi-Fi only and manually upload what you really want to share.
How to know how many GB you use before leaving home
All the tables in the world are worth less than your own data. And you have it on your phone, for free, in two minutes. This is the method I give everyone and it never fails.
- On Android: Settings > Network & internet > SIM or Data usage. You'll see the current cycle's consumption and, if you tap on the history, previous months', broken down by application.
- On iPhone: Settings > Mobile Data. Be careful, the counter there is cumulative since the last time you reset it, so if you've never reset it, the number isn't useful. Reset it today and check it again in a week.
With that monthly data, do the math: divide by 30 to get your daily consumption and multiply by the number of travel days. Now apply two corrections, because traveling is not like your normal life at home. On the downside: at home you use mobile data for commutes and work that you won't do there, and you'll spend hours without looking at your phone. On the upside: you'll take many more photos, search for more things, and use maps daily.
In practice, for most people, both corrections almost cancel each other out, and travel consumption ends up being quite similar to home consumption. If your monthly average is 8 GB, meaning about 270 MB per day, for twelve days in Polynesia you're looking at about 3-4 GB of actual usage. Round up to the next package and you're good to go. And if your average is 40 GB a month because you live on your phone, then you know your profile is different.
How to stretch your data in Polynesia
With four adjustments made before leaving home, the same trip can fit into half the gigabytes. These aren't guru tricks; they're two-minute things that almost no one bothers to touch.
| Adjustment | Where | Estimated savings in 10 days |
|---|---|---|
| Offline downloaded maps for Tahiti, Moorea, and Bora Bora | Google Maps > profile > Offline maps | 200-500 MB |
| Photo and video backups only via Wi-Fi | Google Photos / iCloud > sync settings | 1-4 GB |
| Auto-play video deactivated | Instagram, TikTok, X, Facebook | 500 MB-1.5 GB |
| Data saver activated | System and app settings | 15-30% of total |
| Music and series downloaded before traveling | Spotify, Netflix, YouTube | 500 MB-2 GB |
| App updates only via Wi-Fi | Play Store / App Store | 200-800 MB |
Also, something very Polynesian: download ferry and inter-island flight schedules in PDF before you leave, because they change and you won't always have a signal to check them. The same goes for excursion and diving reservations. I have the complete list of tricks, with screenshots and specific settings, in how to save data while traveling. If you apply only the Wi-Fi backup trick, you've already justified the time invested: it's the one that saves the most gigabytes in a destination where you'll be shooting photos non-stop.
What happens if you run out (and why that's what you want)
Let's talk about what nobody tells you because it doesn't sell: intentionally undershoot. If you buy a small package and it runs out, you recharge and that's it. If you buy a large one and have 8 GB left over, that money has evaporated, because the data doesn't travel with you to the next destination, and nobody will refund it.
When data runs out, nothing dramatic happens: your phone loses internet, you're not overcharged, and no surprise tariffs are activated. You still have Wi-Fi where available, and you can recharge in a couple of minutes from that same Wi-Fi. That's why the expensive mistake is overshooting, not undershooting.
That said, there's a specific nuance for Polynesia that's worth keeping in mind: if your itinerary includes days on atolls with weak coverage, make sure to recharge when you're in Tahiti, Moorea, or Bora Bora, where the signal is good and the process is instant. Don't leave recharging until you're in the south of Fakarava.
My operational recommendation, in three steps:
- Buy the package from the table, without inflating it "just in case."
- Check your consumption on day 3 or 4 of your trip: then you'll know your real pace.
- Recharge only if your pace requires it, and do so from an island with good coverage.
Frequently asked questions
The most common questions I receive about gigabytes for this destination, answered concisely and with the numbers up front.
How many GB do I need for 15 days in French Polynesia?
Between 5 and 10 GB for most travelers. With basic map and messaging use, 3-5 GB is enough for fifteen days. If you upload photos and stories daily, plan for 10 GB. Only if you record 4K video or work from there will you need 15-20 GB.
If French Polynesia is France, doesn't my European plan work?
No, it doesn't work. French Polynesia is an overseas country and territory (OCT), not an outermost region like Guadeloupe, Martinique, or Réunion. The European "roam like at home" regulation does not apply here, and your operator will bill you at international rates, which are especially expensive in the Pacific.
Can I manage solely with hotel Wi-Fi in Bora Bora?
It's risky, and I don't recommend it. Resort Wi-Fi is inconsistent: sometimes free but slow, sometimes better in common areas than in the bungalow, and in some cases, with paid options for higher speeds. It's fine for email; don't count on it for uploading videos.
Is there coverage in Rangiroa and Fakarava?
Yes, but only in the villages. Rangiroa has 4G in Avatoru and Tiputa; Fakarava has limited signal in Rotoava and virtually none in the south of the atoll. Outside populated areas, don't count on data, so carry downloaded maps and reservations.
How many GB do I use uploading diving photos and videos?
A day of 4K diving footage can take up 3-5 GB for uploading. Every minute of 4K video is 300-400 MB. If you're going to record, disable automatic backup, upload only the clips you want to share, and lower the recording resolution to 1080p if you don't plan to edit large files.
What happens if I run out of data halfway through my trip?
Nothing serious: you lose mobile internet and recharge. There are no surprise charges or hidden fees. Just make sure to recharge from an island with good coverage or from Wi-Fi, and don't leave it for a day when you're on a remote atoll.
Do I need data during inter-island flights?
No, you'll be in airplane mode in the air, so consumption is zero. In fact, days with inter-island flights are when you spend the least. What is advisable is to have boarding passes and schedules downloaded, because in small airports, the connection can be patchy.
How many GB for a family of four sharing one phone?
About 10 GB for ten days. Sharing internet from a single phone multiplies consumption, especially if children are watching videos. For fifteen days, plan for 15-20 GB, and limit auto-play and video quality on tablets before leaving home.
Conclusion
In summary, without embellishments: 5 GB for ten days covers most people traveling to French Polynesia, 3 GB if you only use maps and WhatsApp, and 10-15 GB if you're there for two or three weeks uploading photos and videos daily. The factor that truly determines your number isn't the number of travel days, but how much video you upload and how much you trust the accommodation's Wi-Fi, which in Bora Bora and Moorea resorts is exactly the weak point.
And don't forget: even though you're technically in France, your European plan doesn't work in this territory, so arriving without anything arranged is not a cheap option. Choose the package that comes out of the table, without inflating it, and recharge if necessary from Tahiti or Bora Bora, where the signal is plentiful.
If you've already decided, you can get it ready before boarding the plane with the eSIM for French Polynesia: activate it upon landing in Papeete and forget about looking for a store at the airport after twelve hours of flying.
