Why one eSIM beats a SIM per country
A backpacking route through South America usually crosses three to six borders. Buying a local SIM in each country means a new queue, a new registration, a new top-up and a new number every time — and in some countries, a passport registration process that can take an hour. An eSIM for South America keeps the same plan and often the same number across the region, so you arrive in a new country already connected.
What the South America eSIM covers
The South America plan is built for multi-country trips. It covers the main backpacking corridor: Colombia, Peru, Chile, Argentina and more, with data that works as you move. It is not a promise of coverage in every square kilometre of the Amazon or the high Andes — no plan can promise that — but it covers the cities, the transport hubs and the tourist routes where you will actually need it.
If your trip is mostly one country, a single-country plan may be cheaper. If you are crossing borders, the multi-country plan is almost always the better buy.
| Trip type | Best plan | Why |
|---|---|---|
| One country only (e.g. Peru) | Peru eSIM | Local rates, simple |
| Two or more countries | South America eSIM | One plan, no re-buying |
| Patagonia only (Chile + Argentina) | South America eSIM | Cross-border coverage |
| Brazil + neighbours | South America eSIM | Covers the main routes |
Before you fly: check your phone
Not every phone supports eSIM. Before you buy, check your model on the compatibility page: https://esimamericas.com/en/help/check-your-phone. Most recent iPhones, Samsung Galaxy and Google Pixel models work, but it takes a minute to confirm and saves a wasted purchase.
Install before you leave, activate on landing
Install the eSIM at home on Wi-Fi, following the install guide: https://esimamericas.com/en/help/install. Then, when you land, switch it on — the activate guide walks you through it: https://esimamericas.com/en/help/activate. If it does not connect, the troubleshooting page covers the common fixes: https://esimamericas.com/en/help/not-connecting.
Arriving in the big hubs
Most backpacking routes start at a major airport. Each of these guides covers what to do when you land, including getting online:

Crossing borders: what to expect
Land borders in South America can be slow, and Wi-Fi at border posts is unreliable. Having data means you can check onward transport, message your hostel and translate if needed. Our border-crossing guide covers the main crossings and how to stay online: https://esimamericas.com/en/south-america-esim/crossing-borders.
On the classic routes
If your route includes the Inca Trail or the train to Machu Picchu, the Cusco guide explains where signal holds and where it drops: https://esimamericas.com/en/guides/cusco-machu-picchu-staying-connected. For the far south, the Patagonia guide covers El Calafate, Torres del Paine and Ushuaia: https://esimamericas.com/en/guides/patagonia-esim-signal-el-calafate-torres-del-paine-ushuaia. And for the salt flats, the Uyuni guide is here: https://esimamericas.com/en/guides/uyuni-salt-flats-tours-staying-connected.
Data-saving tips for long trips
- Download offline maps before each leg.
- Use WhatsApp for calls — it works over data.
- Turn off auto-play and background app refresh.
- If you run low, top up from the app rather than buying a new plan.
