The Peru trip in three pieces
Most Peru itineraries are some version of three things: a few days in Lima for the food and the colonial center, four to seven days around Cusco and the Sacred Valley (Pisac, Ollantaytambo, Machu Picchu, the train back), and an optional add-on — the Inca Trail, the Salkantay, the Amazon at Iquitos, Lake Titicaca, the Colca Canyon, the Nazca Lines. The cell network covers Lima and the major Andean towns densely, the trekking trails patchily or not at all, and the Amazon mostly on a different planet.
Roamzy charges $1.64 per gigabyte in Peru. That's $0.0016 per megabyte, billed in real time on Peruvian networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 193 countries — same rate in Miraflores as on the train to Aguas Calientes.
How is Roamzy's price calculated?
A typical Peru day uses around 1 GB: Maps for Lima's Metropolitano and the Cusco old town, the camera-translator on a Quechua/Spanish menu, your bank app for card payments (cards work in cities, less reliably at altitude markets), the PeruRail or Inca Rail app for the Machu Picchu train, video calls home. Call it 1 GB/day:
| Trip length | Roamzy ($1.64/GB) | Tourist roaming pass | Local SIM at the airport |
|---|---|---|---|
| 3 days (Lima) | $4.92 | $20–50 | $8–20 + paperwork |
| 1 week (Lima + Cusco) | $11.47 | $40–95 | $15–30 + paperwork |
| 2 weeks (full circuit) | $22.94 | $70–160 (often two passes) | $25–45 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A local SIM at LIM is cheap if you're staying long. Trade is paperwork at the kiosk. The eSIM skips that — pre-installed at home, attached on descent.
Where is Roamzy reliable, and where isn't it?
- Lima, Cusco, Arequipa, Trujillo, Iquitos — solid LTE in the cores, 5G in central Lima
- The Pan-American coast (Lima–Trujillo–Chiclayo) — continuous LTE
- The Sacred Valley (Pisac, Urubamba, Ollantaytambo) — LTE in towns, weakening between
- The Aguas Calientes train run — patchy; brief drops in the river canyon
- The Inca Trail and Salkantay — assume nothing past the first day
- Lake Titicaca (Puno, Uros, Taquile) — LTE in Puno, light on the islands
- Colca Canyon (Chivay, Cabanaconde) — 4G in town, drops on the lookout drives
- Amazon (Iquitos, Puerto Maldonado, jungle lodges) — LTE in the cities, mostly nothing once the boat leaves the dock
If you're trekking the Salkantay or going deep into the Amazon, an offline-cached map (Maps.me, Organic Maps) is baseline kit. The lodges sometimes have satellite Wi-Fi at the main building; cellular is gone.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|

- Sign in to Roamzy via Telegram or Google
- Your first eSIM is free and comes with real data on us. After that, top up from $20 in stablecoins (USDT or USDC): no cards, no banks, no FX surcharges
- The QR code appears in your dashboard as soon as the eSIM is issued
- On the iPhone itself (iOS 17.4 or newer), tap Tap to install in the QR card; otherwise Settings → Cellular → Add eSIM → scan QR
- The counter starts the moment you land at LIM, CUZ, or AQP
Peru runs 220 V at 60 Hz — bring an adapter and check device compatibility. Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
The most useful thing we can tell you about connectivity in Peru is where it won't be. Most eSIM resellers paint the country a solid green and promise "blanket coverage." That's a lie, and it'll catch you halfway up the Salkantay with no signal for two days.
We don't promise blanket coverage. We sell access to the same networks Peruvians use, and we say it plainly: cities and the coast are fast, the Sacred Valley is mostly fine, the trekking trails and the Amazon are luck of the draw. That's geography, not a product flaw.
- No welcome promo that bait-and-switches the second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth both cost $0.0016/MB.
- No auto-renewal. Balance runs out, the eSIM stops.
Peru's tariff is a rate, a meter, and silence where the conditions would normally be. That silence is engineered, and it's also why nobody can genuinely price below it.
What if my route continues across the region?
Peru sits at the heart of Andean South America. The eSIM hands over the moment you cross:
- Chile — common southern continuation via Tacna–Arica
- Colombia — onward via Lima to Bogotá or Medellín
