You've decided to bring data to Chile, and the only thing left is to figure out how many GB to buy for Chile so you don't overspend or run out. I'll tell you this much: Chile is a very long country, you travel it by internal flights, and there are entire stretches—the Tatio geysers, the salt flats, the Torres del Paine trails—where you won't use a single megabyte because there's simply no signal. That lowers the figure much more than people expect, while landscape photography and video push it up. Here's the number, the table by profile, and the nuances that really change the calculation.
The number, first
For 10 days in Chile, most people will have more than enough with 5 GB. If you upload photos and videos daily, count on 10 GB; if you work from your phone or share your connection, 20 GB. Chile helps: Spanish is spoken, there's Wi-Fi in almost all accommodations, and you'll spend entire days without coverage in Atacama and Patagonia.
That's the answer, and I'm not going to stretch it out. What I see over and over again is people buying 20 GB for a two-week trip from Santiago to Torres del Paine and coming home having used six. They pay for data they never touch, and on top of that, the inflated figure doesn't buy peace of mind, it buys a bill.
The reasoning is simple. On a typical trip to Chile, the phone is used for maps, messages, finding places to eat, ordering a car in Santiago, checking the status of an internal flight, and sending photos home. All of that, combined, is around 300-500 MB per day. In ten days, that's 3-5 GB. The rest—social media, video, streaming music, backups—is optional and is exactly where consumption skyrockets if you don't control it.
If you want the general framework for calculating data for any destination, it's elaborated in the main guide on how much data I need for travel. Here I focus on what makes Chile different, which is a lot.
Why Chile changes the number
Chile is over 4,300 kilometers long from north to south. That's not a geographical curiosity: it defines your consumption. A two-week trip usually links three or four very different areas (Santiago, Atacama, Lakes or Patagonia) connected by 2-4 hour internal flights. And you don't use data in the air.
There are four particularities that push the figure down:
- Spanish is spoken. You don't need a camera translator running all day as in Japan or Thailand, and that saves hundreds of megabytes. It's probably the biggest saving compared to Asian destinations.
- Reasonable Wi-Fi in accommodations. City hotels, hostels, and cabins usually have decent Wi-Fi. Atacama and Patagonia lodges, however, have slow Wi-Fi and sometimes limited by hours.
- Hours without coverage. Entire excursions to El Tatio, Valle de la Luna, the altiplano salt flats, or the W circuit: your phone is in your pocket with no signal. Zero consumption.
- Long journeys. Overnight buses and internal flights mean hours with your phone off or in airplane mode.
And two that push it up: Chile is a landscape destination, and people take a lot of photos, so uploading photos and videos is heavy; and if you travel as a couple or family, it's normal for one phone to end up sharing its connection with others. If you're still in doubt about what type of connection suits you, I compare everything in internet in Chile.
How much each thing really consumes
Before choosing a package, it's good to have the magnitudes in mind, because almost everyone makes the same mistake: they think maps consume a lot (they consume very little) and that photos consume little (they consume quite a lot). These are approximate average consumption figures, measured under normal mobile use conditions.
| Activity | Approximate Consumption | In Perspective |
|---|---|---|
| Maps with navigation (normal view) | 5-10 MB per hour | 1 GB provides ~100 hours of navigation |
| Maps in satellite view | 120-150 MB per hour | 15 times more expensive: avoid it |
| WhatsApp text only and voice notes | 1-3 MB per day | Practically free |
| Voice call via WhatsApp | 30-60 MB per hour | Half an hour daily = ~450 MB in 15 days |
| Video call | 300-700 MB per hour | The most aggressive daily expense |
| Social media, scroll (Instagram, TikTok) | 400-800 MB per hour | Half an hour a day is already 3-6 GB in 15 days |
| Upload a mobile photo | 3-5 MB | 20 photos ≈ 60-100 MB |
| Upload a 1-minute video in 1080p | 60-130 MB | Beware of Torres del Paine reels |
| Music streaming (normal quality) | 40-70 MB per hour | An overnight bus with music = ~500 MB |
| Video streaming at 480p | 250-350 MB per hour | Sufficient quality on a mobile screen |
| Video streaming at 1080p | 1.5-2 GB per hour | One movie consumes half a package |
| Browsing, email, transport apps | 20-50 MB per hour | Uber, Cabify or DiDi: ~5 MB per trip |
| Automatic gallery backup | 1-3 GB per week | The silent killer. Deactivate it |
If you want the long detail of each category, with breakdowns by app, I have it in the mobile data usage statistics by activity. What I want you to take away from here is the proportion: browsing the map is noise, video is the entire budget.
How many GB according to your profile and days
This is the table that really matters. Choose your row, look at the column for your days, and you'll have the answer. The figures are calculated for Chile, taking into account the hours without coverage you'll have and with Wi-Fi available in accommodation most nights.
| Profile | 5 days | 10 days | 15 days | 30 days |
|---|---|---|---|---|
| Maps and WhatsApp tourist | 3 GB | 5 GB | 8 GB | 15 GB |
| Photos and social media (uploads daily) | 5 GB | 10 GB | 15 GB | 25 GB |
| Digital nomad / remote work | 10 GB | 20 GB | 30 GB | 50 GB |
| Family sharing (2-4 mobiles) | 10 GB | 20 GB | 30 GB | 50 GB |
A couple of honest clarifications about the table. The maps and WhatsApp tourist row is the one most people fit into without realizing it: if your usage is for orientation, sending audio messages, finding restaurants, and checking email, 5 GB over ten days will be plenty. The photos and social media row assumes you upload 20-40 photos a day and some short videos, not that you spend two hours a day on TikTok; if the latter is your case, add 50%.
The digital nomad assumes short video calls, email, a few meetings, and sharing a connection with a laptop for a while each day. In this case, the margin is money well spent, because running out of data in the middle of a work call costs more than the gigabytes. And for the family row, beware: if everyone is going to use the same phone as a hotspot, count everyone's consumption, not just yours.
Santiago and Valparaíso: this is where most of it goes
It may sound counterintuitive in a country where the beauty is in the desert and the south, but most of your gigabytes will be consumed in the cities. Santiago and the Valparaíso-Viña del Mar axis have solid 4G and 5G in a good part of the metropolitan area, so this is where your phone works at its best and where you, consequently, use it to its fullest.
In Santiago, you'll rely on:
- Transport apps: Uber, Cabify, or DiDi work well and consume very little (about 5 MB per trip), but your phone is on and you're looking at the screen all the time.
- Metro and Red Movilidad: checking routes and times is pure text, barely a few megabytes.
- Finding places to eat: maps, reviews, and local photos. Half an hour of this a day is easily 50-100 MB.
- Uploading to social media: Valparaíso's hills with their murals are among the most photographed things on the trip. This is where the bill goes up.
My practical recommendation: take advantage of Santiago and Valparaíso, which are usually at the beginning of the itinerary, to download everything you'll need later from the hotel Wi-Fi. Offline maps of San Pedro and Torres del Paine, travel music, podcasts for internal flights, and series for the overnight bus. Half an hour of foresight on the accommodation's Wi-Fi is worth more than five gigabytes of a package, and it saves you the typical scene of trying to download a 200 MB map with the barely-there signal of a desert lodge.
Atacama: coverage in town, none on excursions
Atacama is the perfect example of why generic figures fail. San Pedro de Atacama has decent 4G coverage within the town, with the caveat that it gets saturated during peak hours (mid-afternoon, when all the tours return at once). Outside the town, things change radically depending on where you go.
| Area | Typical Coverage | What it means for your GB |
|---|---|---|
| Santiago, Valparaíso, Viña | Solid 4G/5G | This is where you'll spend most of your package |
| Intermediate cities (La Serena, Concepción, Puerto Montt) | Stable 4G | Normal consumption, no surprises |
| San Pedro de Atacama (town) | Decent 4G, saturates at peak hours | Upload photos after returning from the tour, not live |
| El Tatio Geysers, salt flats, and altiplano lagoons | Intermittent or none | Zero consumption for 6-10 consecutive hours |
| Valle de la Luna, Valle de la Muerte | Weak, sometimes | Almost no consumption |
| Puerto Natales and Punta Arenas | Reliable 4G | Charging point and photo upload point |
| Torres del Paine (main entrance and main refuges) | Sporadic and slow | Messages yes, video upload no |
| W and O circuit trails | No signal | Entire days at zero |
| Carretera Austral and rural areas | Long patches without coverage | Have everything downloaded |
| Easter Island (Hanga Roa) | Limited and slow, easily saturated | Don't count on it for work |
The practical consequence for Atacama is good news: a full day excursion to El Tatio, leaving at four in the morning, will cost you close to 0 MB until you return. What you spend is when you get back, when you upload the 80 photos of the day. That's why for many people, a smaller package than they had calculated on paper makes sense. If you're going to set up your connection in advance, I explain the technical part in the guide on eSIM for Chile.
Patagonia and Torres del Paine: entire days without signal
I'm going to be very clear about this because I think it's the most important part of the article: there is no coverage on the Torres del Paine trails. Not with the best Chilean network, not with the best international connection, not even if you pay more. It's not a problem with your data package; it's that there are no antennas.
What you will have:
- Puerto Natales and Punta Arenas: reliable 4G. Everything works normally here.
- Park entrance and main refuges (like Paine Grande or the busiest sectors): sporadic, slow signal and very variable depending on the day and weather. Enough to send an "I'm fine" message, not to upload a video.
- W circuit (4-5 days) and O circuit (7-9 days): assume zero coverage throughout the trek. Some refuges sell paid, slow, and hourly Wi-Fi.
If you're going to do the W, let people at home know before entering the park that you'll be disconnected for several days. It'll save your mother from calling the consulate.
For your gigabyte calculation, this means something very specific: a five-day trek is a five-day zero-consumption trek. If your 15-day trip includes the W, in practice you only consume data for 10 days. Go down one row in the profile table, or stick to the lower end of your range.
What I do recommend doing before entering: download offline maps of the area (Google Maps and a hiking app like Maps.me or similar), have screenshots of refuge reservations, and keep catamaran and bus schedules saved on your phone. All of that weighs less than 300 MB and can be easily downloaded from Puerto Natales' Wi-Fi.
Easter Island: a separate chapter
Rapa Nui deserves its own paragraph because it doesn't behave like the rest of Chile. It's 3,700 kilometers from the mainland, and its connectivity depends on satellite infrastructure and a handful of antennas, with the added peculiarity that there are ancestral heritage areas where they cannot be installed. The result: limited mobile coverage, low speed, and saturation during peak usage hours.
What to expect in practice:
- In Hanga Roa, the town, you have signal for messaging, maps, and basic browsing. It works, but it's not fast.
- Outside the town, traversing the island among the moai, the signal is irregular. Don't count on it.
- Accommodation Wi-Fi is usually slow and shared. It's not a place for work video calls or uploading an entire roll of high-quality photos.
My advice is to treat Easter Island for what it is: a three or four-day break where you'll use very little data, whether you want to or not. Don't inflate your package for going there; on the contrary, it's one of the few places where coverage will impose savings on you even if you don't seek them.
It is advisable to arrive prepared: offline map of the island downloaded from Santiago, Rapa Nui National Park tickets saved on your phone (they are bought online and you will be asked for them), and accommodation and return reservations in image format. And if you are traveling with pending work, resolve it before getting on the plane. Waiting to resolve it from the island is a gamble that often loses.
Photos and video: the silent drain
Chile is a landscape destination, and that comes with a data cost that almost no one calculates correctly. Between the Valle de la Luna, the altiplano lagoons, the hills of Valparaíso, the glaciers, and the Paine horns, people return with 2,000 or 3,000 photos from a two-week trip. The problem isn't taking them: it's what your phone does with them afterward.
Two distinct expenses that should be separated:
- What you upload on purpose: photos to WhatsApp, stories, reels. A photo is 3-5 MB, a one-minute video in 1080p is between 60 and 130 MB. Twenty photos and one reel a day is about 200 MB daily, or 3 GB in fifteen days.
- What your phone uploads automatically: automatic backup of your gallery to Google Photos or iCloud. This can easily go up to 1-3 GB per week and is the number one reason why people run out of data without understanding why.
The solution takes thirty seconds and you should apply it before leaving home: go into Google Photos or iCloud settings and set backups to Wi-Fi only. That's it. Your photos will upload at night from the hotel and won't touch a single megabyte of your plan.
And a quality tip: if you're going to send a lot of photos via WhatsApp, the app compresses them automatically, so don't worry about those. What really takes up space is video. Lower your recording resolution to 1080p if you have it at 4K and you'll notice the difference in both data and free space on your phone.
How to know how much you spend before you leave
All the tables in the world are worth less than your own real data usage. And you have it handy, for free, on the phone you carry. This is the method I use and recommend to everyone before buying a data plan.
On Android: Settings → Network & internet → SIMs or Data usage → you'll see current and previous month's usage, with a breakdown by app. On iPhone: Settings → Mobile Data, and scroll down to the current period's total (the iPhone doesn't reset it automatically, so check the date of the last reset at the bottom of the screen).
With that number, do the two-step calculation:
- Divide by 30 to get your average daily consumption at home.
- Multiply by the number of travel days and subtract between 30% and 50%, because in Chile you'll be out of coverage more hours, walking more hours, and on internal flights more hours than in your normal routine.
Real example: if you use 8 GB per month at home, that's 270 MB per day. For 12 days in Chile, that comes to 3.2 GB, and after the disconnection reduction, you're looking at around 2-2.5 GB. With 5 GB, you'd be more than covered. Your personal number is worth more than any generic recommendation, including mine. And if you're on an unlimited plan and have no reference, start with the row for your profile in the table and top up if necessary. By the way, if this is your first time buying data like this, here's what an eSIM is if you want to understand how it works before deciding.
Stretching data, falling short, and the jump to Argentina
Three practical things to wrap up. First: how to stretch what you buy. With these four adjustments, a 5 GB plan performs like an 8 GB plan:
- Offline maps downloaded for Santiago, San Pedro, Puerto Natales, and Torres del Paine, and always use the normal view, never satellite.
- Backups only via Wi-Fi (the point I mentioned earlier).
- Autoplay video disabled on Instagram, TikTok, X, and Facebook. This is where your plan evaporates without you even realizing it.
- Data Saver mode activated on your system and in apps that have it, plus streaming music and video in low quality.
You can find more tricks, with step-by-step instructions for each setting, in how to save data while traveling.
I much prefer that you buy 5 GB and top up halfway through your trip than buy 20 GB and return with 14 GB unused. Running short can be fixed in two minutes from your phone; overspending can never be fixed.
Second: what happens if you run out of GB. It's not a drama. Your data connection cuts off, and from any Wi-Fi —your hotel, a café, the airport— you top up and continue. That's why it makes perfect sense to buy a smaller plan and top up instead of paying in advance for a margin you probably won't use.
Third, very relevant for this destination: if you cross into Argentina. Many itineraries combine Torres del Paine with El Calafate or El Chaltén, or Atacama with Salta. When you cross the border, your phone connects to an Argentinian network, and a plan bought only for Chile will stop working. If your route covers both countries, look for a regional plan that covers both instead of buying two separately.
Frequently asked questions
How many GB do I need for 10 days in Chile?
5 GB is sufficient for most people. If you upload photos and videos daily, 10 GB. If you work from your phone or share your connection with other devices, 20 GB. Ten days of Santiago-Atacama route with maps, WhatsApp, and some social media rarely exceed 4 GB of actual usage.
Is 3 GB enough for Chile?
Yes, for a short trip of up to 5 or 6 days with normal use. Maps, messaging, looking for restaurants, and sending photos via WhatsApp fit easily within 3 GB. It's not enough if you plan to make long video calls, stream videos, or share your connection with a laptop.
Do I use data in Torres del Paine if there's no coverage?
No: without a signal, there's no consumption. Trekking days on the W or O circuit are literally zero-usage days. That's why it's a good idea to subtract those days from your calculation. Have maps and reservations downloaded before entering the park, because you won't be able to download them inside.
Do I need data on Easter Island?
Very little, and don't expect speed. Coverage in Hanga Roa is enough for messaging and basic maps; outside the town, it's patchy, and Wi-Fi at accommodations is usually slow. Arrive with offline maps and park tickets already downloaded, and a few hundred MB per day will be sufficient.
Can I share data with another phone?
Yes, by activating the hotspot or internet sharing. But account for the consumption of everyone, not just yourself: two people sharing a plan use approximately double. If you're traveling as a couple, either double the gigabytes for your profile, or each person should have their own.
What happens if I run out of GB halfway through my trip?
Your data connection cuts off, and you top up from any Wi-Fi. It takes a couple of minutes, and you continue as if nothing happened. That's exactly why I recommend buying a smaller plan: running short has an immediate solution, overpaying does not.
Is the same plan valid if I cross into Argentina?
Only if your plan covers both countries. When crossing the border towards El Calafate, El Chaltén, or Salta, your phone connects to an Argentinian network, and a plan purchased only for Chile will stop providing service. For combined routes, a regional plan for the Southern Cone is better than two separate ones.
Do check-ins and domestic flights consume data?
Very little: between 5 and 20 MB per transaction. Checking in for LATAM, SKY, or JetSMART, downloading your boarding pass, and checking flight status is mostly text and some images. Download your boarding passes to your phone's wallet, and you won't depend on having a signal at the airport.
Conclusion
In short, for a standard 10-day trip to Chile, 5 GB is the right amount for most people. Increase to 10 GB if you upload photos and videos daily, and to 20 GB if you work from your phone or if several people will be sharing the connection. For 15 days including trekking in Torres del Paine, stick with 8 GB: those trail days won't use any data.
And if you're torn between two sizes, choose the smaller one. Chile will give you hours of disconnection in the desert and Patagonia, and it's much easier to top up than to get a refund for gigabytes you didn't use. Once you've decided, the eSIM for Chile activates in minutes, and you can get it ready before leaving home.
