South America Travel Guide: Argentina, Chile &Peru Itinerary + Best South America eSIM
South America Travel Guide: Argentina, Chile & Peru Itinerary + Best South America eSIM
South America is one of the most rewarding destinations for independent travelers, backpackers and digital nomads. Argentina's tango and steak, Chile's Patagonian glaciers and Atacama starry skies, Peru's Machu Picchu and Inca heritage — these three countries cover the most iconic South American experiences. But when planning a multi-country South America trip, staying connected is one of the biggest practical concerns. This guide covers classic routes through Argentina, Chile and Peru, recommended travel durations, data usage estimates and how to choose the best South America eSIM for your journey.
Should you buy one South America eSIM or a separate eSIM for each country?
- If your itinerary spans two or more South American countries, go with a South America eSIM — one install, one QR code, multi-country coverage, no need to buy and swap eSIMs at each border.
- If you're visiting only one country, a single-country eSIM is more direct: Argentina eSIM, Chile eSIM or Peru eSIM.
- A travel eSIM can be installed before departure and activated by turning on Data Roaming upon arrival — no airport SIM card queues, and you keep your original SIM.
Why Visit Argentina, Chile and Peru in One Trip?
Argentina, Chile and Peru together offer the most diverse travel experiences in South America — from world-class cities to ancient civilizations, from glaciers to deserts, from the Andes to the Pacific. With more flight options and simplified visa processes in recent years, more independent travelers are combining multiple South American countries into a single itinerary rather than visiting just one destination.
Argentina: Tango, Steak & Patagonia
Argentina is South America's second-largest country, offering everything from Buenos Aires' European-style architecture and tango culture to Patagonia's glaciers and trekking trails, to Mendoza's wine region. It's ideal for travelers who love urban culture, outdoor adventure and world-class cuisine, and it often serves as the starting point for multi-country South America routes.
Chile: From the Atacama Desert to Patagonia
Chile stretches along a narrow strip of land from the Atacama Desert in the north to Patagonia in the south, encompassing the driest desert on Earth, world-class astronomical observatories, glacier national parks and Pacific coastline. Santiago is the main gateway for most travelers, while Valparaiso's colorful hills and Atacama's starry skies are must-see highlights.
Peru: Inca Civilization & Machu Picchu
Peru is one of South America's most historically rich countries. From Lima's world-renowned food scene to Cusco's Inca ruins and the breathtaking Machu Picchu, Peru blends ancient civilizations, high-altitude landscapes and Amazon rainforest. For travelers who love history, culture and natural wonders, Peru is often the highlight of a South America trip.
Buenos Aires: The Paris of South America
Buenos Aires is known as the "Paris of South America," with European-style architecture, a vibrant dining scene and tango performances. La Boca's colorful streets, Recoleta Cemetery and the San Telmo Sunday market are classic attractions, making it an ideal first stop for many South American journeys.
Patagonia: World-Class Trekking & Glaciers
Patagonia spans Argentina and Chile, home to Torres del Paine, El Chalten and the Perito Moreno Glacier — some of the world's most spectacular natural landscapes. It's one of the planet's premier trekking destinations, perfect for outdoor enthusiasts and photographers.
Atacama Desert: The Best Stargazing on Earth
The Atacama Desert is the driest place on Earth and one of the world's best astronomical observation sites. Sunset at Moon Valley (Valle de la Luna), sunrise at El Tatio Geysers and crystal-clear night skies make it Chile's most unique northern travel experience.
Cusco: Ancient Capital of the Inca Empire
Cusco was the capital of the Inca Empire, situated at approximately 3,400 meters above sea level. The city preserves a blend of Inca stone walls and Spanish colonial architecture, serving as the gateway to Machu Picchu and the Sacred Valley — and it's a fascinating high-altitude city worth exploring in its own right.
Machu Picchu: New Seven Wonder of the World
Machu Picchu is one of the New Seven Wonders of the World and the pinnacle of Inca civilization. Whether you arrive by train or complete the four-day Inca Trail, standing at the citadel overlooking cloud-wreathed mountains is one of the most unforgettable moments in South American travel.
How Many Days Do You Need for South America?
South American countries are vast and distances between cities are significant — travel time should not be underestimated. With one week, focus on Chile. With 10 days, you can add Peru. To fully explore Argentina, Chile and Peru together, 15 to 21 days is ideal to allow for city exploration and cross-border travel flexibility.

South America eSIM FAQ
What is the best eSIM for South America?
The best South America eSIM depends on your travel countries. If you're only visiting Argentina, Chile or Peru, choose the corresponding single-country eSIM. If your trip spans two or more South American countries, we recommend the South America eSIM — one install covers multiple countries with no need to re-purchase at each border.
Can one eSIM work across Argentina, Chile and Peru?
Yes. The South America eSIM is designed for multi-country travel and covers Argentina, Chile, Peru and other South American countries. Before purchasing, check the destination coverage list on the product page. If you're visiting only one country, a single-country eSIM is usually more direct and economical.
Should I buy local SIM cards in South America?
Buying a physical SIM card at the airport or in the city is a viable option, but it may involve queuing, comparing plans, swapping cards and keeping track of your original SIM. A travel eSIM can be installed before departure, offers faster connectivity upon arrival and is better suited for multi-country travel. If you want to use navigation and ride-hailing apps immediately after landing, an eSIM is usually more convenient.
Can I install the eSIM before departure?
Yes. We recommend installing the eSIM before departure on a stable Wi-Fi connection. Installation does not equal activation — simply turn on Data Roaming after arriving at your destination. Installing before departure avoids dealing with connectivity issues upon arrival.
Do I need to change eSIM when crossing borders in South America?
If you're using a South America eSIM, you typically don't need to swap when crossing borders — one eSIM covers multiple countries. If you're using a single-country eSIM, you may need to install a new eSIM when entering a new country. For multi-country travelers, we recommend choosing the South America eSIM directly.
How much data do I need for South America travel?
For just maps, WhatsApp and basic searches, 5GB is a good starting point for short trips. For general independent travel, consider 10GB. If you frequently use social media, upload photos or videos, 20GB is recommended. For remote work or hotspot use, 30GB or more is advisable.
Can I use hotspot with a South America eSIM?
Yes. The South America eSIM supports hotspot sharing (tethering), allowing you to share mobile data with laptops, tablets and other devices — ideal for digital nomads and remote workers.
Does eSIM work in Patagonia?
Major towns and national park entrances in Patagonia typically have network coverage, but remote mountain areas or trekking routes may have weak or no signal. We recommend downloading offline maps before departure and budgeting extra data. Accommodations in Torres del Paine and El Chalten usually offer Wi-Fi.
Does eSIM work in Machu Picchu?
Network coverage at the Machu Picchu citadel may be unstable. We recommend confirming your connection in Cusco or Aguas Calientes beforehand. The train route to Machu Picchu may also have signal dead zones — download offline maps and your ticket QR code in advance.
Can I keep my physical SIM card when using eSIM?
Yes. Using an eSIM doesn't require removing your original physical SIM card. You can keep your original number for SMS and calls while using the eSIM as your mobile data line. This is especially convenient for travelers who need to receive bank verification codes or stay reachable on their original number.
Which plan should I buy for South America travel?
Choose based on trip length and usage habits. 5GB/10 days is suitable for short trips; 10GB/10 days for general independent travel; 20GB/15 days or 20GB/30 days for in-depth travel or multi-country itineraries. For cross-country travel, we recommend the South America eSIM for broader coverage.
Is eSIM cheaper than roaming in South America?
A travel eSIM is generally more cost-controllable than international roaming fees. Before purchasing, compare your carrier's roaming rates with eSIM plan prices based on your travel duration and data needs. The advantage of an eSIM is that costs are fixed before departure, avoiding expensive roaming bills after you return home.
