Network Usage Tips
Rainforests and remote areas
In remote areas such as the Amazon Basin and Patagonia, signals are extremely weak or nonexistent, so it is advisable to download offline maps in advance. In rural regions, 4G coverage is only 30%, with an additional 15% of areas limited to 2G coverage.
Mountainous areas and plateaus
The Andean Mountains and Patagonian Plateau regions experience unstable signals, with significant disparities in network coverage between urban and rural areas. Rural and remote areas have particularly weak network coverage.
Interior and Historical Buildings
The stone walls and underground areas in the old city can significantly weaken the signal, so it is recommended to use the network near windows or open areas.
Transnational border region
In areas close to national borders (such as the Brazil-Paraguay border or the Colombia-Ecuador border), network switching delays may occur. It is recommended to manually select a network in advance.
Unstable power supply
In some parts of South America, the power supply is unstable, and base stations may experience network outages due to power failures. It is recommended to download necessary materials in places with stable electricity, such as hotels or tourist centers.
Network Congestion Alert
During peak travel seasons (such as Rio Carnival or Machu Picchu's tourist rush), network congestion may occur around popular attractions. It is advisable to avoid using high-bandwidth applications during peak hours. The mobile phone penetration rate in Latin America has reached 133.5%, with rapid growth in 5G users, though 4G users still dominate.
Language support issues
The primary languages spoken locally are Spanish and Portuguese, with limited English support. It is advisable to download a translation app in advance.
Battery Consumption Warning
In areas with weak signals, mobile phones continuously search for networks, leading to faster battery drain. It is advisable to carry a portable charging device. Many countries have expanded network coverage and improved its quality through the integrated application of various technologies such as 4G and 5G.
Price assessment
In South America, 78% of the population in eight countries lives within 3G/4G network coverage, but there is a significant urban-rural divide (85% 4G coverage in urban areas compared to only 30% in rural areas). Mobile data pricing in these eight countries falls within a reasonable range, with basic urban plans (500MB-2GB/day) sufficient for daily needs, while remote areas may require plans exceeding 2GB to ensure uninterrupted usage. According to GSMA data, mobile data prices in South America have dropped by 55% since 2015, though network quality varies noticeably across regions. As of March 2023, eight Latin American countries—including Brazil, Colombia, Argentina, Chile, Peru, and Uruguay—have launched commercial 5G services, offering users faster connectivity. Across the Americas, 419 cities have deployed 5G, with ongoing improvements in network infrastructure.
