eSIM coverage guide for South America travel from the UK
South America's mobile landscape ranges from excellent 4G in major coastal cities to no signal at all in the Amazon basin, Atacama Desert, and Patagonian wilderness. Understanding where coverage works and where it ends is critical for safe travel planning.
Brazil is South America's largest market, with Claro, Vivo (Telefonica), and TIM Brasil serving the country. Sao Paulo, Rio de Janeiro, Brasilia, and all coastal capitals have strong 4G and growing 5G. But the Amazon rainforest covering the north has almost no coverage.
Argentina has solid 4G in Buenos Aires, Cordoba, and Mendoza through Claro, Movistar, and Personal. Patagonian towns like Bariloche and Ushuaia have 4G in the town centres.
The vast Patagonian steppe between towns, Ruta 40 in remote sections, and the end-of-the-world roads south of Ushuaia have no coverage.
Chile connects via Entel, Movistar Chile, and Claro in Santiago, Valparaiso, and northern wine regions. The Atacama Desert towns of San Pedro de Atacama have reasonable coverage. Patagonia (Torres del Paine area) has no coverage in the national park itself.
Peru has 4G in Lima and Cusco through Claro Peru and Movistar Peru. Machu Picchu Pueblo (Aguas Calientes) has 4G. The Inca Trail and highland trekking routes have no coverage.
Colombia has excellent 4G in Bogota, Medellin, and Cali through Claro, Movistar, and Tigo. The Coffee Region and Caribbean coast are well-served for tourism.
A HelloRoam South America regional eSIM switches carriers automatically as you cross borders, so your Buenos Aires coverage transitions smoothly to Uruguayan carriers, or from Brazil's Iguazu side to Argentina's.
- One plan covers 12 countries with automatic border switching
- Major coastal cities have strong 4G and growing 5G
- Amazon basin, Atacama, and Patagonian wilderness have no coverage
- Machu Picchu Pueblo (Aguas Calientes) has 4G, but the Inca Trail does not
- Patagonia requires complete offline preparation before entering national parks
- Both sides of Iguazu Falls (Brazil and Argentina) are covered

eSIM Travel Tips for South America
Patagonia requires full offline preparation
Torres del Paine National Park in Chile and Los Glaciares National Park in Argentina have no mobile coverage inside the park boundaries. Puerto Natales and El Calafate towns have 4G. Download offline maps (including the W Trek and O Trek routes for Torres del Paine), guesthouse GPS coordinates, and emergency contacts before entering any Patagonian national park.
Amazon basin has no coverage
The Brazilian, Peruvian, and Colombian Amazon have no mobile coverage away from river towns. Manaus has 4G in the city. River lodge tours, Amazon jungle walks, and eco-camps in the forest are completely without signal. Download wildlife guides, emergency numbers, and your lodge's GPS before any Amazon river journey.
Machu Picchu has 4G at the town, not the trail
Aguas Calientes (Machu Picchu Pueblo) has functional Claro Peru and Movistar Peru coverage. The bus ride up to the Machu Picchu citadel and at the citadel itself has some coverage. The four-day Inca Trail has no coverage between camps. Download the Inca Trail route, permit PDF, and emergency contact for your guide operator before trekking.
Iguazu Falls has coverage on both sides
Iguazu Falls on the Brazilian side (Foz do Iguacu) has Claro Brazil and Vivo coverage. The Argentine side (Puerto Iguazu) has Claro Argentina and Movistar Argentina coverage. Crossing the border by bus, your HelloRoam eSIM switches from Brazilian to Argentine carriers automatically.
Check FCDO travel advice for each country
The UK Foreign, Commonwealth and Development Office (FCDO) publishes travel advisories for all South American countries. Several countries have elevated warnings for certain areas. Check current FCDO advice before visiting any South American destination and follow local safety guidance.
Buenos Aires has excellent urban coverage
Buenos Aires has Claro Argentina, Movistar Argentina, and Personal 4G coverage throughout the city. The Subte (subway) system has coverage at stations, with some tunnel sections having weaker signal. La Boca, Palermo, San Telmo, Puerto Madero, and all main barrios are well-connected.
Emergency numbers vary across South America
Emergency numbers across South America differ by country. Brazil: 190 (police), 192 (ambulance), 193 (fire). Argentina: 911 (police and ambulance). Chile: 133 (police), 131 (ambulance). Colombia: 123. Peru: 105 (police), 116 (ambulance). Save country-specific numbers before each border crossing.
Network coverage across South America: what British travellers need to know
South America's mobile market is dominated by two pan-regional operators: America Movil (operating as Claro) and Telefonica (operating as Movistar). These two companies operate in nearly every country, giving consistent network partnerships for regional eSIM plans.
Brazil's mobile market is the largest in the region with over 200 million subscribers. Claro, Vivo (Telefonica), and TIM Brasil compete across Brazil's vast geography. Sao Paulo has strong 5G in central areas. Rio de Janeiro's coverage extends along beaches and into favela communities. The north (Amazon states) remains largely uncovered.
Argentina's Claro, Movistar, and Personal serve a country of major geographic contrasts. Buenos Aires's urban network is sophisticated. The wine country of Mendoza and Cordoba are well-served. But Argentina's Patagonian provinces are enormous and sparsely populated.
Chile's Entel leads in national coverage quality. Santiago's network is excellent. Chilean Patagonia (Punta Arenas, Puerto Natales) has town coverage with wilderness gaps.
Colombia has rapidly improved. Bogota and Medellin have competitive 4G and early 5G. The Caribbean coast (Cartagena, Santa Marta) is well-covered for tourism.

Best times for South American travel data
South America's vast size means travel seasons vary dramatically by region. Patagonia (Chile and Argentina) is best visited from November to March (Southern Hemisphere summer) when weather permits trekking. Network demand in Puerto Natales and El Calafate peaks in January and February.
Brazil's Amazon dry season runs June to November, when river levels drop and wildlife concentrates. Peru's Inca Trail and Machu Picchu have peak demand from May to September. The trail closes in February for maintenance.
