Best internet cities in South America

Overview

Santiago tops our ranking of best internet cities in south america at 8.0/10, just ahead of Montevideo and Sao Paulo. "Best internet cities in South America" is one of the most searched relocation questions we track — and most articles answering it are written from a single traveler's memory, not from consistent data across cities. Ranked purely on internet and connectivity infrastructure. We isolated every city in South America from the full 303-city database and sorted that regional subset purely by best internet, so the comparison stays fair within the region instead of getting diluted by cities on other continents. It's worth noting the spread: scores here range from 8.0 down to 6.0, so position #1 and position #30 aren't just marginally different — they represent genuinely different day-to-day experiences. The gap between the #1 and #3 spots is often smaller than it looks: a 0.3-point difference in an aggregate score can come from a single criterion, so it's worth opening a city's full scorecard rather than trusting the headline number alone. If you've already decided on South America and just need to narrow it down by best internet, this is the fastest way to do it — for a fuller picture, cross-reference with the overall livability ranking for the same region. Below is the complete list with every underlying score, plus links through to a full breakdown for each city.
