Your Ultimate Guide to eSIMs in South America
Traveling through South America is an adventure of a lifetime, from the Amazon rainforest and Andean peaks to vibrant cities and Patagonian glaciers. Yet, staying connected with reliable mobile data can be a significant challenge. Roaming with your home carrier is notoriously expensive, and navigating local SIM cards in foreign languages is often confusing. This is where the revolutionary technology of the eSIM comes in. This comprehensive guide will walk you through everything you need to know about using an eSIM for travel across South America, ensuring you have seamless, affordable, and hassle-free connectivity from Colombia to Chile.
What is an eSIM and Why Use One in South America?
An eSIM (embedded SIM) is a digital SIM card embedded in your device. Instead of a physical plastic chip, you download a data plan profile directly to your phone, tablet, or smartwatch. For travelers, this is a game-changer. You can purchase and activate a regional or local data plan before you even board your flight, avoiding airport kiosks and language barriers upon arrival.
Key Advantages of an eSIM for South American Travel
- Instant Activation: Buy online and get connected the moment you land.
- Multi-Country Plans: One plan can cover multiple countries—perfect for cross-border trips.
- No Physical Swapping: Keep your home number active for 2FA texts while using data on your eSIM.
- Easy Top-Ups: Renew or add data via an app, no need to find a store.
- Cost-Effective: Drastically cheaper than international roaming packages.
Device Compatibility: Is Your Phone eSIM-Ready?
Before purchasing, verify your device supports eSIM technology. Most modern smartphones from the last 3-4 years do. Key compatible models include:
- iPhone: All models from iPhone XS, XR, and newer (including SE 2nd & 3rd gen).
- Samsung Galaxy: S20 series and newer, Z Fold/Flip series, and many A-series models.
- Google Pixel: Pixel 3 and newer.
- Other Brands: Selected models from Motorola, Huawei, and Sony.
Pro Tip: Check your device settings. On iPhone, go to Settings > Cellular > Add Cellular Plan. On Android, go to Settings > Connections > SIM manager. If you see an « Add eSIM » option, your device is compatible.
Choosing the Right South America eSIM Plan
Providers offer various plans tailored to different travel styles. Your choice depends on your itinerary, data needs, and budget.
1. Regional Multi-Country eSIM Plans

- Example Plan: 10GB of data valid for 30 days across 10+ South American countries.

- Best For: Extended stays, digital nomads, deep exploration of one nation.
- Example: A Brazil-only plan might offer 20GB for 30 days at a lower cost per GB than a regional plan.

Country-by-Country Connectivity Tips
Network quality varies. Here’s what to expect in key destinations:
Brazil
Vivo, Claro, and TIM are the major carriers. Coverage is excellent in cities and along the coast but can be spotty in the Amazon interior. Regional eSIMs usually partner with one or all of these.
Argentina
Personal, Claro, and Movistar are the main networks. Speeds in Buenos Aires are good, but expect slower connectivity in Patagonia and remote areas.
Peru, Bolivia, and Ecuador
Claro and Movistar dominate. Connectivity is reliable in Lima, Cusco, and La Paz but can be very limited on trekking routes like the Inca Trail or in the Amazon basin. Download offline maps and crucial information beforehand.
Chile
Has some of the best infrastructure. Entel, Movistar, and Claro offer strong coverage even in parts of Patagonia.
Common Pitfalls and How to Avoid Them
- Misconfigured Settings: Double-check that your home SIM’s data is OFF and your eSIM’s data roaming is ON.
- Ignoring Network Selection: If you’re not connecting automatically, manually select a network from the list provided by your eSIM app.
- Running Out of Data: Monitor your usage in your phone settings. Most provider apps allow easy top-ups.
- Not Checking Specific Country Coverage: Always verify that your chosen plan explicitly includes every country on your itinerary, especially smaller nations like Guyana or Suriname.
Beyond Data: Making Calls and Using WhatsApp
Most travel eSIMs are data-only. Here’s how to handle calls and texts:
- Use VoIP Apps: Leverage WhatsApp, FaceTime Audio, Google Meet, or Skype for calls and messages over data. This is the standard communication method across South America.
- Keep Your Home SIM Active: For receiving important SMS (like bank two-factor codes), keep your physical SIM in the phone but with cellular data disabled.
- Purchase a Local Calling Add-On: Some providers offer a local number for incoming calls/SMS, or credit for making local calls.

Adopting an eSIM for your South American journey is one of the smartest travel tech decisions you can make. It eliminates the stress of finding a local shop, dealing with language barriers, and overpaying for roaming.
