Stay Connected in South America
Network coverage, costs, and options
Connectivity Overview
South America's connectivity landscape varies dramatically by country and region. Major cities like São Paulo, Buenos Aires, and Santiago offer excellent 4G/5G coverage with speeds comparable to North America and Europe. However, rural areas and smaller countries often struggle with patchy coverage and slower speeds. Countries like Chile, Uruguay, and parts of Brazil lead in infrastructure quality, while Bolivia, Paraguay, and remote areas of Peru and Colombia can be challenging. Internet costs are generally reasonable in urban areas, but data prices vary significantly between countries. The key is understanding that your connectivity experience will largely depend on your specific destinations - stick to major cities and tourist routes for reliable service, but prepare for limited options when venturing into remote areas like Patagonia or the Amazon basin.
Get Connected Before You Land
We recommend Airalo for peace of mind. Buy your eSIM now and activate it when you arrive—no hunting for SIM card shops, no language barriers, no connection problems. Just turn it on and you're immediately connected in South America.
Network Coverage & Speed
Network quality across South America is highly variable by location. In Brazil, operators like Vivo, Claro, and TIM provide solid 4G coverage in major cities, with 5G expanding rapidly in São Paulo and Rio. Argentina's Movistar, Claro, and Personal offer good urban coverage but struggle in rural areas. Chile leads the region with excellent nationwide coverage from Entel, Movistar, and Claro, including decent service in remote areas. Colombia's Claro, Movistar, and Tigo provide reliable urban service, while Peru's coverage is concentrated around Lima and tourist areas like Cusco. Ecuador, Uruguay, and Bolivia have more limited but functional networks in populated areas. Speeds in major cities typically range from 20-80 Mbps download, dropping to 1-10 Mbps in rural areas. The Andes mountains create significant coverage gaps, and jungle regions often have no service at all. Tourist areas generally have better infrastructure than the national average, but always have backup plans for remote destinations.
How to Stay Connected
eSIM
eSIMs offer significant convenience advantages for South America travel, especially for multi-country trips. You can activate service before leaving home, avoiding language barriers and airport SIM card shops that often overcharge tourists. Providers like Airalo offer regional South America plans covering multiple countries, which is perfect for typical tourist circuits. The main downside is cost - eSIMs typically run 2-3x more expensive than local SIMs, though you're paying for convenience and immediate connectivity upon arrival. eSIMs work well if you need moderate data usage (1-10GB), but heavy users will find them expensive. They're particularly valuable in smaller countries where finding legitimate SIM cards can be challenging, or when crossing borders frequently. Most newer smartphones support eSIM, but verify compatibility before traveling. The peace of mind and instant connectivity often justify the premium for vacation travelers.
Local SIM Card
Local SIM cards offer the best value for extended stays or heavy data users. In major countries, buy from official carrier stores (Claro, Movistar, Vivo) rather than airport kiosks to avoid inflated tourist pricing. You'll need your passport for registration, and activation usually takes 15-30 minutes. Prepaid plans typically cost $10-25 for 5-15GB monthly, significantly cheaper than eSIM options. However, each country requires a separate SIM, creating hassle for multi-country trips. Language barriers can complicate purchases, especially explaining data vs. call needs. Some carriers require local addresses or have complex activation processes. Rural coverage may be limited even with local SIMs. Street vendors sell SIMs cheaply but often lack proper activation support. Consider this option for stays over one month in a single country, or if you're on an extremely tight budget and comfortable navigating local telecom systems.
Comparison
Local SIMs win on pure cost - typically 50-70% cheaper than eSIMs for equivalent data. However, eSIMs dominate on convenience: no hunting for carrier stores, no language barriers, no registration hassles, and immediate activation. Roaming from home carriers is usually prohibitively expensive ($10-15/day). For most travelers, the time saved and stress avoided with eSIMs justifies the premium. Local SIMs make sense for extended single-country stays or extreme budget constraints.
Our Recommendations
First-time visitors: Go with eSIM from Airalo - the convenience factor is huge when you're already dealing with new currencies, languages, and logistics. Having connectivity the moment you land is invaluable for navigation and booking confirmations. Budget travelers: If every dollar matters, local SIMs save money, but eSIMs aren't much more expensive and save considerable time and stress. Consider the value of your time spent finding and configuring local SIMs. Long-term stays (1+ months): Local SIMs become cost-effective for extended single-country visits, offering better rates and often better network priority. Business travelers: eSIM is essential - you need immediate connectivity for emails and calls, can't waste time in carrier stores, and the cost difference is negligible compared to trip value. The reliability and instant activation make eSIM the only practical choice for professional travel.
Our Top Pick: Airalo
For convenience, price, and safety, we recommend Airalo. Purchase your eSIM before your trip and activate it upon arrival—you'll have instant connectivity without the hassle of finding a local shop, dealing with language barriers, or risking being offline when you first arrive. It's the smart, safe choice for staying connected in South America.
