Altitude note
Cusco sits at 3,400m — data matters early
Why landing with data already on matters more in Peru
Most guides tell you an eSIM saves you an airport queue. In Peru there's a second, more practical reason: Cusco is at 3,400 meters, and a meaningful chunk of visitors feel some version of altitude sickness in the first day — a headache that won't quit, nausea, trouble sleeping. You want to be able to look up a pharmacy, message your hotel about coca tea or an oxygen tank, or just search your symptoms at 3am without relying on patchy lobby Wi-Fi.
Beyond altitude: the SIM counter itself is a minor hassle
Jorge Chávez International in Lima has SIM kiosks in arrivals, but they keep limited hours and the queue can run long after a late international flight. An eSIM activated before you board means you land in Lima with signal already, no kiosk stop needed before your connecting flight to Cusco.

Network
Strengths
Best for
Claro
Widest reach into the Andes and Sacred Valley towns; strong in Cusco, Arequipa, and along the Cusco-Puno route; most commonly used by international eSIM providers
Full Peru circuit — Lima, Cusco, Sacred Valley, southern Peru
Movistar
Comparable urban coverage in Lima and Cusco; occasionally better around Arequipa and Lake Titicaca; solid overall second option
Lima-Cusco city trips, southern Peru extensions
Entel
Cheaper local plans; decent coverage in major cities
Budget local SIMs for city-only stays; less useful for rural or Andes travel
Coverage by destination
Lima
Full 4G across Miraflores, Barranco, and downtown. The Costa Verde coastal cliffs and the historic center around Plaza Mayor: all covered. One of the best-connected capitals in South America.
Cusco
Good 4G through the historic center, Plaza de Armas, and San Blas neighborhood. Signal holds up well even on the steep cobblestone streets above San Blas where taxis won't go.
Sacred Valley (Pisac, Ollantaytambo, Urubamba)
Solid coverage in all three towns and along the main valley road. The Pisac ruins on the hillside above town: signal holds up to the top. Ollantaytambo's fortress terraces: covered.
Inca Trail
Signal exists near Ollantaytambo (the trailhead) and fades within the first few kilometers. The classic 4-day trek is mostly a dead zone — some guides carry satellite phones for exactly this reason. Tell someone your itinerary before you start; don't rely on checking in along the way.
Machu Picchu & Aguas Calientes
Aguas Calientes town: decent 4G. The bus up to the ruins and the entrance gate: patchy but present. Inside the citadel itself: unreliable, and mostly absent past the main viewpoint. Screenshot your entry ticket before you board the bus.
Arequipa & Colca Canyon
Arequipa city: excellent coverage, one of Peru's best-connected secondary cities. Colca Canyon: coverage in the town of Chivay and at the main condor-watching viewpoint (Cruz del Cóndor), but weak to absent on the canyon trails themselves.
Lake Titicaca (Puno)
Puno town: good 4G. The floating Uros Islands: surprisingly decent signal given they're literally built from reeds. Taquile Island further out: patchier, drops to 2G/3G in places.
Amazon basin (Iquitos, Puerto Maldonado)
Iquitos and Puerto Maldonado towns: workable coverage. Jungle lodges more than an hour upriver typically have no signal at all — most rely on satellite internet for the lodge itself, and guests are effectively offline for the stay. Budget for this rather than fight it.
How much data do you need in Peru?
Data pulls more weight here than in a lot of destinations — not just for maps and photos, but for altitude-sickness lookups on day one in Cusco, offline navigation through the Sacred Valley's winding mountain roads, and translation apps once you're past the well-trodden Cusco-Machu Picchu stretch and English gets rarer.

Offline map tip for the Sacred Valley
Download Cusco, the Sacred Valley, and the Ollantaytambo-Aguas Calientes route offline before you go. If you're doing the Inca Trail, don't count on signal at all for four days — download everything in advance and let your trekking agency handle emergency communication, since that's what the satellite phone in the guide's pack is for.
Frequently asked questions
Does eSIM work in Peru?
Yes. Claro, Movistar, and Entel all support eSIM. Good 4G in Lima, Cusco, Arequipa, and the Sacred Valley. Machu Picchu's ruins, the Inca Trail, and the deeper Amazon basin have little to no coverage.
Which network is best: Claro or Movistar Peru?
Claro generally has the widest reach into the Andes and Sacred Valley. Movistar is competitive in Lima and Cusco and sometimes better around Arequipa and Titicaca. Either works fine for a standard tourist route.
Is there signal at Machu Picchu?
Aguas Calientes town has decent 4G. Inside the ruins themselves, signal is unreliable and mostly absent past the classic viewpoint. Screenshot your ticket before heading up.
Why does data matter more in Cusco than other destinations?
Cusco sits at 3,400 meters and altitude sickness affects many visitors in the first day or two. Having working data on arrival to look up pharmacies, symptoms, or message your hotel is genuinely useful, not just a convenience.
Is there signal on the Inca Trail?
Very little. Coverage exists near the Ollantaytambo trailhead and fades within the first few kilometers. Most of the 4-day trek has no signal — trekking agencies typically carry a satellite phone for emergencies.
