If you already know you're going to need data and the only thing left is to decide on the size, this guide is for you: how many GB do I need for Peru and why the number you need there is lower than you imagine. Peru has a peculiarity that almost no one mentions: a good part of the trip takes place in areas where your phone has no one to talk to, and that changes the calculation.
The short answer, no beating around the bush
For two weeks in Peru doing the classic circuit of Lima, Cusco, Sacred Valley, and Machu Picchu, 5 GB is more than enough for most people. If you only use maps and WhatsApp, 3 GB will suffice. And if you upload video daily or work remotely from Cusco, count on 10 or 15 GB.
I know it sounds like little. We're used to 50 GB plans at home, and it's daunting to leave with 5. But at home, your phone is on and connected to the mobile network sixteen hours a day, with Spotify in the background, videos on the subway, and work email syncing every two minutes. On a trip to Peru, your phone spends many hours a day in camera mode: inside a ruin, on a high-altitude bus, on a train without signal, or on an island in Lake Titicaca. It doesn't consume because it can't.
Add to that the fact that in Peru, you speak Spanish. It sounds trivial, but the camera translator is one of the biggest data guzzlers on a trip to Japan, China, or Morocco, and here you simply won't open it. No translator, no deciphering menus, no ordering a taxi with hand gestures. That consumption disappears from the budget.
If you want the general criterion I apply to any destination before delving into Peruvian specifics, you'll find it in the main guide on how much data you need for travel. Here, I'll focus on Peru specifically.
Why Peru consumes less than you think
This is what makes Peru different and what really saves you money. A large part of what you'll do there happens out of coverage, and not by chance: these are precisely the places you went for.
- The Inca Trail and multi-day treks have no coverage. Salkantay, Choquequirao, Lares, Ausangate, the classic four-day Inca Trail: during those days, your phone is a camera with a flashlight. Zero data consumed.
- Machu Picchu has limited and irregular signal. You might get a connection at the entrance or on some high terrace, but don't count on it inside the citadel. Photos are uploaded later, from the hotel.
- The train to Aguas Calientes is a tunnel of silence. The journey from Ollantaytambo is nestled in the Urubamba canyon, and you lose signal for a good part of the round trip.
- The Amazon ends at the town. Iquitos and Puerto Maldonado have decent 4G in the center, but as soon as you get on the boat to the lodge, it's over. Most jungle lodges operate with shared satellite internet, when they have it.
- The islands of Titicaca and the upper reaches of Colca are patchy. There's signal in Puno and Chivay, but between towns there are many miles of nothing.
My mental calculation: on a two-week circuit in Peru, between four and six days are spent on long excursions, treks, or in the jungle. Days when you'll spend a fraction of what you spend in Lima. That's why 5 GB goes so far there and falls short on a city trip of the same duration.
If you also want to understand your connection options and how Peruvian operators' coverage works, I've detailed it in the internet in Peru guide. This article assumes you've already made your decision.
What does drive up consumption there
Now for the other side. There are three very Peruvian things that increase expenses and should be kept in mind to avoid underestimating.
Lima and transport apps. Lima is very well connected and is a city where you'll constantly order cars via apps: Uber, inDrive, or Cabify are part of the routine for moving between Miraflores, Barranco, the center, and the airport. Each journey involves live maps, chat with the driver, and real-time tracking. It's not dramatic (a trip is around 5-10 MB), but if you do four or five a day, it adds up. Add to that the fact that in Lima you'll want to upload stories, look for restaurants, and read reviews.
Lots of photos and videos. Peru is one of those destinations that generates the most shots per minute. Machu Picchu, Rainbow Mountain, Colca, Maras and Moray, the markets of Cusco. A modern phone takes photos of 3 to 5 MB, and a one-minute video in high quality can easily reach 150 MB or more. If you have automatic backup turned on with mobile data, that's the leak that devours your plan in three days, not social media.
Altitude and waiting times. It sounds strange, but it's real: in Peru, you spend many hours sitting. High-altitude bus rides of six or eight hours, waits in Aguas Calientes, afternoons of acclimatization in Cusco lying in your hotel because altitude sickness has knocked you out. And when there's signal and downtime, you consume. That's the pattern: days of nothing followed by afternoons of much.
How much each activity consumes, in real MB
Before choosing a size, it's good to have an honest order of magnitude. These are average consumption figures per hour of active use. I round up so that the estimate gives you some leeway:
| Activity | Approximate Consumption | Note for Peru |
|---|---|---|
| Maps with live navigation | 5-10 MB per hour | Almost zero if you have the map downloaded |
| WhatsApp (text, audio, some photos) | 20-40 MB per day | The most typical use during the trip |
| WhatsApp video call | 300-450 MB per hour | Better with hotel Wi-Fi |
| Social media browsing feed | 500-750 MB per hour | Instagram and TikTok are the most expensive |
| Upload 20 photos to the cloud | 60-100 MB | Multiply by each day of travel |
| Upload a 1-minute video | 100-200 MB | The silent killer of your plan |
| Music streaming | 40-70 MB per hour | Download it before long bus rides |
| Video in medium quality (720p) | 500-700 MB per hour | In 1080p it goes above 1 GB |
| Email, news, and browsing | 10-20 MB per hour | Ridiculous compared to video |
| Order a car via app (per trip) | 5-10 MB | Frequently used in Lima |
The conclusion is obvious: maps, messaging, and browsing consume almost nothing; video and automatic uploads consume everything. With that in mind, you can estimate your case quite well. If you want a complete breakdown by application, with more categories, I have it compiled in the data usage statistics by activity, which is where I get the figures I use for calculation.
Table: GB according to your profile and number of days
This is the table that truly matters. Find your profile, cross-reference it with your travel days, and you'll have your number. It's calculated using the real Peruvian pattern, meaning, discounting trek, train, and jungle days when you won't consume anything:
| Profile | 5 days | 10 days | 15 days | 30 days |
|---|---|---|---|---|
| Maps and WhatsApp, little else | 1 GB | 2 GB | 3 GB | 5 GB |
| Normal tourist: photos, social media, looking for places | 2 GB | 3 GB | 5 GB | 10 GB |
| Content creator: uploads video daily | 5 GB | 10 GB | 15 GB | 30 GB |
| Digital nomad or remote work | 8 GB | 15 GB | 20 GB | 40 GB |
| Family or couple sharing one phone | 3 GB | 5 GB | 8 GB | 15 GB |
Look at the row for the normal tourist, which is where most people fall: 15 days with 5 GB. That's the sweet spot for the typical two-week trip with organized excursions. If your agency takes you everywhere by bus and you sleep in hotels with Wi-Fi, you might even have some left over.
Two honest caveats. The first: if you're someone who takes a very urban trip and stays a full week in Lima without leaving, move up a notch, because there is permanent coverage there and the temptation to use it. The second: if you travel with an agency that provides Wi-Fi on the bus or you always stay in good hotels, move down a notch. These two adjustments explain almost all the difference between travelers.
The classic circuit, stage by stage
To see where the numbers come from, here's the typical circuit broken down by what you can expect at each stage. This table also helps you plan what to do with Wi-Fi and what to save for when there's a signal:
| Stage | Expected Coverage | Daily Consumption |
|---|---|---|
| Lima (Miraflores, Barranco, downtown) | Very good, 4G and 5G | High: transport apps and social media |
| Flight or bus Lima-Cusco | None in the air, intermittent on the road | Almost none |
| Cusco city | Good, with Wi-Fi in all accommodations | Medium |
| Sacred Valley (Pisac, Maras, Ollantaytambo) | Signal in towns, gaps in between | Low |
| Train to Aguas Calientes | Practically none in the canyon | None |
| Aguas Calientes | Signal available, saturated at peak times | Medium: when you upload photos |
| Machu Picchu citadel | Limited and irregular | Almost none |
| Inca Trail, Salkantay and other treks | No coverage | None, several days in a row |
| Arequipa and Colca Canyon | Good in the city, irregular in the canyon | Medium and low |
| Puno and Titicaca Islands | Good in Puno, weak in Uros and Amantaní | Low |
| Amazon: Iquitos and Puerto Maldonado | 4G in town, nothing at the lodge | None outside town |
With this picture in front of you, you understand why the number is low: on a fifteen-day itinerary, easily five or six days contribute almost zero to the counter. The good strategy is to use Cusco, Lima, and Aguas Calientes to clear your pending uploads, preferably connected to the hotel's Wi-Fi. If you're still deciding which plan to contract, in the eSIM for Peru guide, I tell you more about how coverage works in each area.
How to calculate YOUR consumption before leaving
All of the above are averages, and averages lie. The good news is that you have the exact data of your own consumption in your pocket, for free and without installing anything. It's the most useful exercise in this guide and takes two minutes.
- On Android: Settings, Connections or Network & internet, Data usage. You'll see your mobile data for the current cycle and a breakdown by application.
- On iPhone: Settings, Mobile Data. Scroll down to the app list and check the current period. It's a good idea to reset the statistics on the 1st of the month to get a clean measurement.
Take your monthly consumption, divide it by 30, and you'll have your MB per day at home. Now apply the Peruvian adjustment: on a trip, you consume about half of what you do daily, because you sleep with Wi-Fi, spend hours without coverage, and aren't on the couch watching videos. Multiply that half by your travel days and compare it with the profile table. If the two numbers are similar, you've got it right.
A warning: also check which application is at the top of that list. If your number one is YouTube, Instagram, or TikTok, move up a notch in the table without hesitation, because that habit travels with you. If your number one is WhatsApp or Google Maps, you can safely move down. That detail predicts your consumption better than any generic estimate.
Tips for stretching your gigabytes in Peru
With four adjustments made before leaving home, the same package will last twice as long. None of them force you to give up anything important:
- Download offline maps of Lima, Cusco, the Sacred Valley, Arequipa, and Puno. Google Maps still gives you your location via GPS without data, so it works even on a full trek. It's the most cost-effective trick of all.
- Backups only over Wi-Fi. Go into Google Photos or iCloud and disable uploads over mobile data. This is, by far, the number one cause of surprises with your data counter.
- Data saver mode activated on your phone and within each large app. It compresses images, cuts background activity, and you won't notice the difference.
- Autoplay video disabled on Instagram, TikTok, X, and Facebook. Watching a video because you want to is one thing; having twenty videos you didn't ask for autoplay is another.
- Download entertainment before bus rides. Peruvian journeys are long: put music, podcasts, and a series on your phone from the hotel Wi-Fi, and you won't touch your data during eight hours on the road.
With these habits, a normal traveler will end up using significantly less than half of what they would consume without making any changes. I have the complete list, with specific settings for each application, in the article on tricks for saving data while traveling.
If there are several of you: data sharing and hotspot
Here's a decision that many people don't consider, and it changes the budget. If there are two or four of you traveling, not everyone needs data. A very sensible option in Peru is for only one person to carry the data plan and share it via hotspot when needed: checking the map, ordering a car in Lima, looking for a restaurant. The rest just use hotel Wi-Fi.
It works well because in Peru, people travel in groups almost all the time. You're together on the bus, together on the excursion, and together at the hotel. It's not like a European city where everyone goes their own way. However, it has two drawbacks that should be known: the hotspot significantly drains the battery of the sharing phone, and in a country where you spend the day out and about in cold, high-altitude conditions, battery is a scarce resource. Definitely bring a power bank.
The second drawback is distribution: when there's a hotspot, people use it as freely as home Wi-Fi, and the data counter skyrockets. If you're going to share, move up to the family profile in the table and discuss the rules beforehand: maps and messaging yes, videos and app updates, no.
My practical recommendation for a couple on a two-week trip: a 5 GB package for the "guide" and a 3 GB package for the other person, instead of one large shared one. This way, neither of you is stranded if the hotspot runs out of battery in Ollantaytambo.
What happens if you run out (and why it's not a big deal)
I'll say it clearly, even though we sell larger packages: it's better to run short and top up than to overshoot. If you buy 3 GB and run out on day eleven, you top up from your phone in two minutes and continue. If you buy 20 GB and only use 4, you've wasted money, and there's no going back.
When you run out of data, nothing dramatic happens: your phone stops having mobile internet, but you still have Wi-Fi in hotels, cafes, and restaurants, which are abundant in tourist areas in Peru. The maps you downloaded still work, and so does the GPS. You won't be incommunicado; you'll just be without data until you top up.
What I do recommend is to activate the data usage alert in your phone settings before you leave: set a limit and an alert when you're halfway through your data plan. This way, you'll know on day seven that you're using data quickly and can adjust, instead of finding out at the worst possible moment, which is usually when you're looking for your hotel at night in an unfamiliar city.
And one last idea about when to top up: do it in Lima, Cusco, or Arequipa, where there's good coverage and you can do it calmly. Don't leave it until you're coming down from Colca or arriving in Aguas Calientes at night, because the signal there is usually weak, and everything becomes more inconvenient than necessary.
Frequently Asked Questions
How many GB do I need for 15 days in Peru?
For a classic two-week tour, 5 GB is more than enough for a normal traveler. With downloaded maps and backups only via Wi-Fi, many even end up using less, because trek, train, and jungle days don't add anything to the data counter.
Is there coverage on the Inca Trail?
No, the Inca Trail does not have mobile coverage. During trek days, your phone serves as a camera, flashlight, and GPS with downloaded maps, but not as a phone. The same applies to Salkantay, Lares, or Choquequirao. Inform home before you start.
And is there a signal in Machu Picchu?
Coverage within the citadel is limited and irregular. You might catch something at the entrance or in the higher areas, but don't count on uploading live stories. In Aguas Calientes, there is a signal and Wi-Fi in hotels, which is where you'll have to upload the day's material.
Do I need data in the Amazon?
In Iquitos and Puerto Maldonado, yes; in the lodge, no. The towns have reasonable 4G, but as soon as you go deeper into the jungle, coverage ends, and the lodges rely on slow, shared satellite internet. You won't spend anything on those days.
Can I share my data with my partner?
Yes, using your phone's hotspot or tethering function. This is a very reasonable option in Peru because you travel together almost all the time. Keep in mind that it consumes battery on the sharing phone and that usage increases, so plan accordingly with your family's profile.
What happens if I run out of data halfway through the trip?
You top up from your phone and continue in a couple of minutes. In the meantime, you still have hotel and restaurant Wi-Fi and offline maps. That's why it's worth buying a smaller plan: topping up is easy, but unused gigabytes are not refunded.
Will my data work as soon as I land in Lima?
Yes, if you have everything installed and configured from home. It's best to do it with your home Wi-Fi and activate it upon arrival. If you're not sure how the process works, I explain it step-by-step in the guide on what an eSIM is.
Conclusion
Peru is one of the few destinations where I can honestly tell you to buy a small amount of data. Five GB for two weeks is the honest recommendation for the typical traveler on the Lima, Cusco, Sacred Valley, and Machu Picchu circuit. Three GB if you're mainly using maps and WhatsApp. Increase to 10 or 15 GB only if you telework or upload videos daily, and for nothing else.
The country works in your favor: treks with no coverage, the train to the canyon, the islands of Titicaca, and jungle lodges are zero-consumption days. Download maps before you go, save backups for hotel Wi-Fi, and you'll see how your plan lasts longer than you expected. Once you've decided, choose the size that fits you for the eSIM for Peru and don't worry: if you run short, you can top up from your phone in two minutes and continue your trip.
