Peru’s mobile market is shared by Claro, Movistar, Entel and the budget challenger Bitel, with broad 4G LTE across Lima, the coast and the main tourist circuit, and 5G now appearing in central Lima. Coverage is dependable in Cusco, Arequipa, the Sacred Valley towns and along the Pan-American Highway, but thins out fast on Andean trekking routes and in the Amazon basin. Travelers can grab a tourist SIM at Lima’s Jorge Chávez airport (LIM) or install a travel eSIM before arrival.
Networks & coverage
Claro and Movistar have the widest national footprints and are the most reliable choice for travel beyond the cities; Entel is strong in Lima and major hubs with the most active 5G; Bitel surprises with good rural reach in some Andean and jungle regions. 5G is still mostly a Lima story. Travel eSIMs generally roam on Claro or Entel, giving solid coverage on the Lima–Cusco–Machu Picchu corridor, though remote trekking sections will still go dark.
eSIM or physical SIM?
Tourist SIMs are sold at the LIM airport arrivals area and at carrier stores in town; you’ll need your passport to register. A local SIM is cheap and gives you a Peruvian number, handy for confirming tours and transfers. A travel eSIM (Airalo, Holafly, Nomad, Saily) is the zero-paperwork option — install before you fly and you’re online the moment you land, which is convenient if you arrive late and skip the airport counters.
Data, calls & messaging
Travel eSIMs are data-only, and WhatsApp is the default for calls and chat across Peru, so a data plan plus WhatsApp serves most visitors. Some Airalo Peru plans now bundle a small allowance of local minutes and SMS; a local Claro or Movistar SIM gives full domestic calling at low prices. For a typical Cusco-and-Machu-Picchu trip, a data eSIM with WhatsApp covers tours, transfers and navigation.
How much data do you need?
A week of maps, messaging and light browsing fits in 3–5 GB. Two weeks across Lima, Cusco and the Sacred Valley with social media suits about 10 GB. Heavy users uploading trek photos or working remotely should aim for 15–20 GB. Because signal is patchy on multi-day treks, download offline maps and music before you head into the mountains rather than relying on data there.
