What "unlimited" usually means on a travel eSIM
When a travel eSIM is advertised as unlimited, the small print almost always describes one of two things:
- A daily high-speed allowance. You get a set volume at full speed each day, then speeds drop to something usable for messaging and maps but not for video.
- A total cap with a fair-use policy. The plan is unlimited until you pass a threshold, after which the provider can throttle or suspend the line.
Neither is a lie, but neither is what most people picture when they read the word. If your trip involves uploading photos, working remotely, or streaming, a fixed bundle with a known size is easier to plan around than a vague "unlimited" promise.
What you can actually buy for Peru
Peru eSIM plans are sold as data bundles. You choose the size, install the eSIM before departure, and the plan activates when it connects to a network in Peru. There is no SIM queue at Jorge Chávez International Airport and no contract to sign.
You can see the live Peru plans and sizes on the Peru eSIM store page. If your trip continues into Ecuador, Chile, Argentina or Brazil, the South America eSIM covers multiple countries on one plan instead of one eSIM per border.
| Trip style | What to buy | Why |
|---|---|---|
| Lima only, long weekend | Small Peru bundle | Maps, rides, messages; hotel Wi-Fi covers the rest |
| Lima, Cusco, Sacred Valley | Mid-size Peru bundle | Trains, transfers, altitude days with patchy Wi-Fi |
| Peru plus another South American country | South America multi-country plan | One eSIM across borders, no re-install |
| Remote work or heavy uploads | Larger Peru bundle | Fixed volume beats a throttled "unlimited" line |
Before you buy: check your phone
An eSIM only works on an eSIM-capable, carrier-unlocked phone. Most recent iPhones, Samsung Galaxy models and Google Pixels qualify, but it is worth confirming in a minute rather than at the gate. The phone compatibility check walks through it.
Install before you fly, activate when you land
Two steps, in this order:
- Install the eSIM at home, on Wi-Fi, while you still have a stable connection and your order email in front of you. The installation guide covers both QR-code and manual methods.
- Switch it on after landing. Leave your home SIM active for calls and turn on the Peru eSIM for data. The activation guide explains the settings on iPhone and Android.
If the line does not connect in the first few minutes, that is usually a settings issue rather than a coverage one; the not-connecting troubleshooting page works through the common causes.
Arriving in Lima
Most Peru trips start at Lima airport. Immigration and baggage can take a while, and the arrivals hall is where you will want data for a ride, a translation or a message home. Having the eSIM already installed means you are online the moment you clear customs. For the practical detail on terminals, taxis and getting into the city, see Lima airport (LIM): arriving and getting online.
Cusco, the Sacred Valley and Machu Picchu
Signal in Peru is best in Lima, Arequipa, Cusco and the main towns. It thins out on the Inca Trail, in the Sacred Valley's more remote stretches, and on some train sections. That is normal for mountain terrain and not a fault of the eSIM. Download offline maps before you leave Cusco, and treat connectivity as a bonus rather than a guarantee on trekking days. Our guide to Cusco to Machu Picchu: staying connected on the trail and the train covers what to expect where.
Crossing into neighbouring countries
Peru sits next to Ecuador, Colombia, Brazil, Bolivia and Chile. If your itinerary crosses a land border, a single-country Peru eSIM will stop working on the other side. Two options:
- Buy the South America eSIM before you leave, so the same plan carries you across borders.
- Buy a separate eSIM for each country if you prefer country-specific plans.
The South America: crossing borders and staying online guide covers the practical side of land crossings.
Data sizing: a rough guide
- Light use (maps, messaging, occasional search): around 1 GB per week.
- Moderate use (social media, photos, some video): around 3–5 GB per week.
- Heavy use (remote work, video calls, cloud uploads): 10 GB per week or more.
Hotel and café Wi-Fi in Lima and Cusco is generally reliable, so you rarely need to cover every hour of the day. The point of the eSIM is the gaps: airports, transfers, trekking days and the moments when the Wi-Fi does not reach.
What to do if something goes wrong
If the eSIM stops working, loses its QR code, or you need a refund, the help centre is the starting point. There is no public order lookup page; per-order links arrive by email, so keep that message. Refunds and lost QR codes are handled through the refunds page.
