Peru is three countries stacked into one. A desert coast, a mountain range that reaches 6,700 metres, and a stretch of Amazon rainforest larger than most European nations. Your phone behaves differently in each of them.
That variety creates a problem travellers rarely plan for. Lima and Cusco have solid 4G. Two hours outside either city, on a mountain road or a jungle river, you may have nothing at all. And getting a local SIM card is harder than it used to be: since 2024, Peruvian operators require a national ID and biometric registration to issue a prepaid line, which most foreign visitors simply cannot provide.
An eSIM avoids all of it. You buy it online, install it at home, and connect the moment you land at Jorge Chávez airport. This guide covers ETravelSim's Peru plans, where signal actually works, when to visit, and seven places worth going that most visitors never reach.
Where your signal actually works in Peru
Coverage in Peru follows terrain, not distance. A town three hours from Cusco may have full bars while a valley twenty minutes away has none.
Two points are worth being blunt about, because a lot of marketing is not.
Inside the Machu Picchu citadel, signal is intermittent on every Peruvian network. The mountains block line of sight to the towers. Use your phone for photos, not for live navigation.
On the Inca Trail and at Rainbow Mountain, expect long dead zones. This is not a provider problem. No carrier covers those routes properly. Download offline maps before you set off.
Quick Tip
Download Google Maps offline for Cusco, the Sacred Valley and Lima before you fly. Combined they take a few hundred megabytes and they solve most connectivity problems in Peru before they happen.
Peru's mobile networks
Peru has four national operators: Claro, Movistar, Entel and Bitel. Coverage in Lima, Arequipa, Cusco and along the coastal highway is good on all of them. The differences appear in the Andes and the Amazon, where tower density drops sharply.
The ETravelSim Peru eSIM runs on a national 4G/LTE network covering Lima, Cusco, Arequipa and the Sacred Valley, which is where most travellers spend their time. If your itinerary is heavy on remote Andean routes or the Amazon basin, expect variable signal, and know that this is true of every carrier in those regions.

Which plan should you pick?
- Lima stopover, two or three days: 1 GB at $4.50
- One week, Lima plus Cusco and Machu Picchu: 5 GB at $8.99
- 10 to 14 days, the standard Peru trip: 10 GB at $14.99
- Long overland routes with bus tethering: 20 GB at $24.99
- Working remotely for a month: 50 GB at $44.99
- Do not want to count at all: Unlimited, from $19.00 for 7 days
Important: hotspot is allowed on every plan
This matters more in Peru than in most countries. Bus Wi-Fi on overland routes is unreliable, and long Andean journeys are common. Tethering from your phone is often the only way to get a laptop online, and it works on all ETravelSim Peru plans including Unlimited.
How much data do you need in Peru?
| Traveller type | Typical usage | Suggested plan |
| Light user | Maps, WhatsApp, occasional browsing | 2 to 3 GB |
| Regular traveller | Maps, Uber, social media, photo uploads | 5 to 10 GB |
| Heavy user | Video calls, streaming on night buses | 20 GB |
| Remote worker | Cloud services, laptop tethering | 50 GB or Unlimited |
As a rough guide: a one-week trip covering Lima, Cusco and Machu Picchu fits inside 3 GB to 5 GB. A two-week trip adding Arequipa, Colca Canyon and Lake Titicaca is more comfortable on 10 GB, because long bus journeys mean more navigation and more tethering than city travel.
Best time to visit Peru
Peru has no single best month, because the Andes, the coast and the Amazon run on different seasons. The Andean dry season, roughly May to September, is the peak for Machu Picchu and the Inca Trail. That is exactly when Lima is grey and cool under its coastal fog.
Month by month
| Months | What to expect |
| May and September | The sweet spot. Dry in the Andes, clear skies at Machu Picchu, shoulder pricing, and far fewer people than mid-winter. |
| June to August | Peak season and peak crowds. Driest and coldest in the Andes, with cold nights in Cusco. Book Machu Picchu tickets and Inca Trail permits months ahead. |
| October and November | Shoulder season. Rain starts returning to the highlands but the landscape turns green and prices drop. |
| December to March | Wet season in the Andes. Afternoon downpours, muddy trails, and cloud that can hide the citadel entirely. This is the best time on the coast, and Lima is at its sunniest. |
| February | The Inca Trail closes for the entire month for maintenance every year. Machu Picchu itself stays open, reached by train. |
Important: Machu Picchu booking rules changed for 2026
Entry is now by timed slot on a fixed, one-way circuit chosen at the moment you buy. Re-entry is not permitted, and rangers check that visitors stay on their assigned route. Tickets and Inca Trail permits are capacity-controlled and high-season dates sell out months in advance. Book well ahead through official channels or an authorised operator, and confirm exactly what your ticket includes.
Where to go in Peru
Cusco and the Sacred Valley
The base for almost every Peru trip. Cusco itself is a former Inca capital with Spanish colonial buildings sitting on Inca stone walls. The Sacred Valley below it, taking in Pisac, Urubamba and Ollantaytambo, is lower, warmer and better for acclimatising. Budget four to five days including Machu Picchu.
Machu Picchu
Reached by train from Ollantaytambo or Cusco to Aguas Calientes, then by bus or a steep hour's walk. Signal in Aguas Calientes is reliable. Inside the citadel it is not. Go early or take the last slot of the day, when the light is better and the crowds thinner.
Lima
Worth more than the airport transfer most visitors give it. Barranco and Miraflores for the clifftop walk above the Pacific, the Larco Museum for pre-Inca collections, and some of the best restaurants in South America. Two days is enough.
Arequipa and Colca Canyon
Arequipa is built from white volcanic stone, sits below three volcanoes, and has the best weather of any Peruvian city. Colca Canyon, three hours north, is more than twice as deep as the Grand Canyon and is one of the most reliable places in the world to see Andean condors. Three to four days.
Lake Titicaca
The highest navigable lake in the world at 3,810 metres, shared with Bolivia. The floating Uros islands are built from totora reeds and rebuilt continually. Taquile and Amantaní offer homestays with far fewer visitors. Two days from Puno.
Seven hidden gems beyond Machu Picchu
Peru receives millions of visitors a year and most of them follow the same route. These seven are genuinely worth the detour.
| Place | Best months | Why go |
| Choquequirao | May to September | An Inca city comparable in scale to Machu Picchu, reached only by a two-day trek. Receives a tiny fraction of the visitors. Only around a third of the site has been cleared. |
| Kuélap and Gocta | May to September | A vast pre-Inca stone fortress in northern cloud forest, built by the Chachapoya centuries before the Inca. Gocta waterfall nearby is one of the tallest in the world. |
| Huaraz | May to September | The Cordillera Blanca has the highest concentration of peaks above 6,000 metres outside the Himalaya. Laguna 69 and the Santa Cruz trek are the classics. |
| Huacachina | Year round | A genuine desert oasis in the sand dunes near Ica, four hours south of Lima. Sandboarding and dune buggies, best at sunset. |
| Máncora | December to March | Peru's far north coast, where the water is warm enough to swim without a wetsuit. Surfing, seafood, and a much slower pace. |
| Iquitos | May to September | The largest city in the world unreachable by road. Gateway to the Peruvian Amazon, with river lodges and the Pacaya-Samiria reserve. |
| Colca Canyon | April to November | Condors at Cruz del Cóndor most mornings, terraced valleys farmed since pre-Inca times, and hot springs at the canyon floor. |
Altitude and signal at Peru's big sights
Altitude affects both your body and your phone. It is also the single most underestimated part of a Peru trip.
The detail that catches people out: Cusco is roughly a kilometre higher than Machu Picchu. Most altitude sickness happens on arrival in Cusco, not at the citadel. Arrive two days before any trek, drink far more water than feels necessary, and go easy on the first evening.
How to install your Peru eSIM
Before your trip
- Check that your phone supports eSIM and is carrier-unlocked. Dial *#06# and look for an EID.
- Buy the eSIM online. The QR code arrives by email.
- Connect to Wi-Fi at home and add the eSIM by scanning the QR code.
- Label the line, then leave it switched off until you land.
When you arrive in Peru
- Turn off airplane mode.
- Select the ETravelSim line as your default for mobile data.
- Turn on data roaming for that line.
- Turn data roaming off on your home line so it cannot generate charges.
- Check that data is working before you leave the airport.
Practical quick-reference
| What | Details |
|---|---|
| Currency | Peruvian sol (S/). Cards are widely accepted in cities; carry cash for markets, small towns and trailhead fees. |
| Language | Spanish, plus Quechua and Aymara in the highlands. English is limited outside tourist areas, so a translation app is genuinely useful. |
| Local SIM cards | Difficult for tourists. Peruvian operators require national ID and biometric registration for prepaid lines, which most visitors cannot provide. |
| Power | 220V. Sockets accept both flat two-pin (Type A) and round two-pin (Type C) plugs. |
| Water | Do not drink from the tap. Bottled or filtered water only, including for brushing teeth in rural areas. |
| Altitude | Cusco is 3,400 m and Puno 3,810 m. Allow two days to acclimatise before trekking. Coca tea helps mildly; time helps more. |
| Getting around | Domestic flights save days on a long country. Overnight buses on major routes are comfortable and cheap. Trains serve the Sacred Valley and Lake Titicaca. |
| Tipping | 10% in restaurants where service is not included. Small tips for guides and porters are customary and appreciated. |
| Safety | Generally safe for tourists in the main destinations. Use registered taxis or ride-hailing apps rather than street cabs in Lima, and watch belongings in crowded markets. |
Peru eSIM FAQs
What is the best eSIM for Peru in 2026?
The best plan depends on your route and trip length. For most travellers doing Lima, Cusco and Machu Picchu over 10 to 14 days, 10 GB is the practical choice. Check that hotspot is allowed if you plan to tether, and that validity starts on first use rather than at purchase.
Will the eSIM work at Machu Picchu and in the Sacred Valley?
Yes in Aguas Calientes and across the Sacred Valley towns of Ollantaytambo, Pisac and Urubamba. Inside the citadel itself, signal is intermittent for every Peruvian carrier because the terrain blocks the towers. Use it for photos and offline maps rather than live navigation.
Does it work on the Inca Trail or at Rainbow Mountain?
Expect long dead zones on both. This applies to all networks in Peru, not just one provider. Download offline maps before you set off and treat any signal you do get as a bonus.
How much data do I need for a Peru trip?
For one week with maps, WhatsApp, photo uploads and Uber, 3 GB to 5 GB is enough for most people. 10 GB covers a 10 to 14 day trip with regular social media. Choose 20 GB or unlimited if you stream on long bus journeys or tether a laptop.
Can I use the eSIM as a hotspot?
Yes, on every ETravelSim Peru plan including Unlimited. On unlimited plans, hotspot use counts toward the 4 GB daily high-speed allowance, after which you can keep tethering at 1 Mbps.
Does the Peru eSIM include a phone number?
No. It is data-only, with no Peruvian number, no incoming calls and no SMS. Use WhatsApp, FaceTime or Zoom over the eSIM data instead, and keep your home SIM active for calls and bank verification codes.
Why not just buy a local SIM at the airport?
Peruvian operators require a national ID and biometric registration to issue prepaid lines, which most foreign visitors cannot satisfy. Airport kiosks charge well above city rates, and street-vendor SIMs are registered to someone else, which causes problems later.
When does the validity period start?
When you first use the eSIM in Peru, not when you buy or install it. Install it at home before flying and the timer only begins once your phone connects on arrival. Do not delete the profile after installing, because reinstalling is not always possible.
Can I keep my home SIM active?
Yes, on any dual-SIM phone. Your home SIM handles calls and SMS while the eSIM handles data. Switch data roaming off on the home line to avoid charges.
What is the best month to visit Peru?
May or September for most itineraries. Both are dry in the Andes, cheaper than mid-winter, and far less crowded than June to August. December to March is the wet season in the highlands but the best time on the coast.
Is the Inca Trail open all year?
No. It closes for the whole of February every year for maintenance. Machu Picchu itself stays open and is still reachable by train. Permits are capacity-controlled and sell out months ahead for high season.
How bad is the altitude in Cusco?
Cusco sits at about 3,400 metres, which is higher than Machu Picchu. Most travellers feel it on the first day. Arrive two days before any trek, take the first evening slowly, and drink plenty of water.
Does the Peru eSIM work in Bolivia or Chile?
No. This plan covers Peru only. If your trip crosses borders, look at a regional plan or buy a separate eSIM for each country.
Summary
Peru rewards planning more than most destinations, because the distances are long, the altitude is real, and the connectivity is uneven.
Get three things right and the rest follows. Buy 5 GB to 10 GB for a standard trip and install it before you fly. Download offline maps for Cusco, the Sacred Valley and Lima. And give yourself two days in Cusco before any trek.
