Internet in Peru: the Inca Trail and the Colca with no signal

Peru is travelled with the phone in your hand for half the day and without it for the other half, and that is what to understand before buying anything. In Lima, Cusco or Arequipa the connection is as good as at home; the moment you start climbing — the Colca, the Cordillera Blanca, any three- or four-day trek — the signal disappears and does not come back until the next village. This guide covers what to expect from coverage, why buying a local SIM has become complicated for foreigners, and what to have downloaded.

How to get online in Peru

Roaming with your own carrier

Peru sits in the expensive zone of most tariffs: a daily pass with a few hundred megabytes, or pay per use. For two or three weeks on the road it virtually never works out. Check your specific tariff before leaving.

A Peruvian SIM: there is new small print

This is the part almost nobody has updated. Peru tightened mobile line registration in late 2025, and for foreigners signing up became in person and with a biometric fingerprint check against the immigration database. It is tied to the state of emergency in Lima and Callao, so in theory it is temporary, but it has been repeatedly extended and was still in force in late August 2026.

The problem is obvious: a tourist who has just arrived does not usually have fingerprints in that database, and if it does not validate, the carrier is barred from selling you the line. We cannot tell you exactly what they will say today at the Jorge Chávez airport counter, which is why the advice is the same either way: do not arrive in Peru depending on getting a local chip.

Travel eSIM

You buy the days of the trip, install the QR at home on wifi and land connected to a Peruvian network as a roaming visitor. Your own line stays in the phone, data off, for bank texts. It is bought outside the country, so it falls outside the Peruvian registration rules and depends on no procedure on arrival. In a destination with paperwork moving this much, that is the real advantage.

Real coverage: who covers what, and where it ends

Four networks: Claro, with the most customers; Bitel (Viettel), which has grown fast on rural rollout; Entel, more urban and coastal; and Movistar, which in the regulator’s coverage data reaches the most populated territory. Travel eSIMs latch onto one of them.

Good, with 4G and 5G in the main cities: Lima, Cusco, Arequipa, Trujillo, Chiclayo, Piura, Huaraz town, Puno, Aguas Calientes and the Sacred Valley villages (Pisac, Urubamba, Ollantaytambo).

Where it ends:

• Inca Trail: some signal the first morning and on the final stretch; the rest, nothing.
• Salkantay and the high passes: virtually no coverage until you drop down towards Santa Teresa.
• Colca Canyon: signal in Chivay and Yanque; the descent into the canyon and the villages at the bottom, no.
• Cordillera Blanca (Laguna 69, Santa Cruz): intermittent and unreliable as soon as you leave Huaraz.
• The Amazon: Iquitos town has 4G; as soon as the boat leaves the city the signal collapses, and at the reserve lodges you should not count on it.

One detail that surprises people in Cusco: Inca walls and the thick adobe of colonial hotels swallow the signal indoors. Your phone not working inside your room does not mean the plan is faulty.

And the usual warning: the eSIM connects to Claro’s, Movistar’s or whoever’s network, it brings none of its own. Where there is no mast, no eSIM works, ours or anyone else’s.

Altitude, cold and battery: what genuinely changes

Two physical things that really show in Peru. First: cold destroys battery life. A night camping at 4,000 metres leaves the phone with half the endurance you expect, and charging it below freezing does permanent damage. Sleep with it inside your sleeping bag.

Second: with no coverage, the phone spends all day hunting for a network and uses far more power. On a multi-day trek, airplane mode is not disconnecting for fun — it is what gets you to the end with battery left. Switch it on only when you know there is signal.

Hence the advice that sums up this guide: download the maps beforehand. Google Maps lets you save whole areas offline, and for hiking Organic Maps or OsmAnd work better because they include the trails. Download your Machu Picchu ticket, your train bookings and your accommodation contact too.

How much data you need

Peru concentrates your usage: whole days at zero in the mountains and then an afternoon in a city uploading everything at once.

Type of trip	Typical use	Plan that fits
Cities and Sacred Valley: maps, messaging, photos	300-500 MB a day	5 GB for a week
The above plus social posting daily	700 MB - 1 GB a day	10 GB for two weeks, or unlimited
Video, video calls, tethering a laptop	Over 1.5 GB a day	Unlimited by days

The breakdown app by app is in how much data do I need for a trip.

Installing the eSIM and landing connected

1. Compatibility: dial *#06# and look for the EID; the phone must be carrier-unlocked. List by brand on compatibility.
2. Buy for the days of the trip: validity starts with the first connection in Peru.
3. Install at home on wifi. Name it “Peru”.
4. Lines: your home line for calls and texts with its data off; the eSIM as mobile data with roaming on.
5. On landing in Lima: turn off airplane mode and wait to see “Claro”, “Movistar”, “Entel” or “Bitel”. Having it sorted before leaving the terminal lets you book your transfer in the app rather than at the door.

Apps people use in Peru

• Uber, Cabify, DiDi and InDrive all work in Lima and Cusco; having two installed helps you compare and avoids being stranded at certain hours. At night, an app rather than a street taxi.
• Google Maps with Lima, Cusco, Arequipa and the Sacred Valley downloaded, and Organic Maps for mountain routes.
• PeruRail and Inca Rail for the trains to Aguas Calientes: bought online with a foreign card, and in high season worth booking weeks ahead.
• WhatsApp: agencies, hostels and drivers organise everything there. Your own number works fine.
• Payments: card in hotels, restaurants and city agencies; cash in soles for markets, colectivos, smaller tickets and anything rural. Always be charged in soles and refuse to let the ATM or card machine convert to your own currency: that conversion is always worse.

Connectivity tips

• Before each trek: map downloaded, route left with your hostel, power bank charged.
• The regulator (OSIPTEL) publishes a coverage checker by district on its site. If you are going to a specific village and want to know which carrier reaches it, it takes a minute.
• Long-distance buses (Cruz del Sur, Oltursa) advertise wifi that rarely works. Download what you want to watch beforehand.
• Bank verification texts arrive on your home line, which stays active; receiving them costs nothing.
• If the route continues to Bolivia or Chile, a Peru-only plan stops at the border: look at regional plans.

Rough price

The block at the top shows what a Peru eSIM costs in the MovaSim catalogue today, with the unlimited-by-days option and the cheapest by gigabytes; the Peru page has every plan and what each covers. And if you do end up with a Peruvian chip, the coverage, map and battery advice here applies exactly the same.
