Staying connected across South America
One Americas plan covers 16 countries including Peru, Chile, Argentina and Brazil, so you skip the SIM shop at every border. Budget 3–5 GB for a week in one country, 8–12 GB for two weeks across several, 12–15 GB for a month of border-hopping. Download offline maps for the Inca Trail, RN-40 and the Amazon interior.

South America rewards the prepared traveler. Coverage is genuinely excellent in cities and along the main tourist routes, and noticeably thinner in the Andes, the Amazon and deep Patagonia. Plan for those offline stretches and you’ll glide from Lima to Ushuaia without a connectivity headache.
One plan, many borders
A regional Americas plan covers 16 countries, including Peru, Chile, Argentina, Brazil, Colombia and Bolivia, so you’re not hunting for a new SIM at every crossing. That matters here, where buying a local SIM can mean a passport, a local tax ID, and a shop that’s closed for siesta.
Budget a little extra
Plan for slightly more data than you’d use in Europe, because the day-to-day leans hard on your phone:
- Ride-hailing (Uber, Cabify, DiDi) running maps for every trip.
- Offline-map downloads for each new region.
- Translation for menus and buses if your Spanish or Portuguese is rusty.
10–15 GB comfortably covers most month-long itineraries; add an unlimited plan if you’ll hotspot a laptop for remote work.
| Trip | Suggested data |
|---|---|
| 1 week, one country | 3–5 GB |
| 2 weeks, multi-country | 8–12 GB |
| 1 month, border-hopping | 12–15 GB |
| + remote work / hotspot | Unlimited |
Where the signal drops
Expect little to no coverage on the Inca Trail, the Salar de Uyuni, Amazon riverboats, and long stretches of Patagonian highway. Before each leg, download offline maps while you still have strong city signal, and screenshot key addresses and bookings. For the Bolivian leg in particular, our Bolivia coverage guide shows where the signal still holds between La Paz and the salt flats.
Keep your home number alive
Many South American banks, airlines and booking sites still verify with an SMS code. Keep your home SIM installed (data roaming off) so those texts arrive while Zwitchy handles the data. Spending most of the trip in one country? Our Argentina coverage guide goes network by network from Buenos Aires down through Patagonia. If Colombia is on the itinerary, our Colombia coverage guide maps which networks hold up from Bogotá out to the Caribbean coast. Chile is worth its own read: the Chile coverage guide follows the signal from the Atacama all the way down to the far south.
Country-by-country quick notes
- Peru: strong in Lima, Cusco and along the Gringo Trail; expect dead zones on the Inca Trail.
- Chile: Entel reaches furthest down through Patagonia; the Atacama and far south drop offline.
- Argentina: solid in Buenos Aires and Mendoza; long stretches of RN-40 have no signal.
- Brazil: Vivo and Claro cover the coast and big cities well; the Amazon interior does not.
Stay-connected safety tips
Phone snatching happens in some cities, so don’t wave your handset on the street, screenshot directions before you set off. Keep offline maps and your accommodation address saved, and email yourself a copy of the eSIM’s QR / activation details so you can reinstall on a backup phone if needed.
