Why Multi-Country Travellers Need an eSIM Strategy
South America is one of the most popular backpacking regions in the world, but staying connected across multiple countries used to mean buying a new SIM card at every border. eSIM technology has changed that, but now the question is which approach actually saves you money without sacrificing convenience.
The answer is not straightforward. There are three fundamentally different approaches, each with real trade-offs that depend on how many countries you are visiting, how long you are staying, and how much data you actually use. This guide breaks down the real costs -- with actual prices as of March 2026 -- so you can make an informed decision before your trip.
Three Approaches to South America eSIM Connectivity
Every multi-country traveller faces the same choice: pay less per gigabyte with individual plans, or pay more for the convenience of one plan that works across borders.
Option 1: Individual Country eSIMs (LATAM Travellers)
This is what LATAM Travellers specialises in. You buy a separate eSIM for each country on your itinerary. As a Latin America eSIM specialist, our coverage spans 22 Latin American countries with plans starting under $4 per country.
How it works: Install all your eSIMs at home before departure. When you cross a border, open Settings, tap the new country's eSIM, and disable the old one. The whole process takes about 30 seconds.
Pricing as of March 2026 (all prices in USD, approximate at time of writing):
| Country | 3 GB / 15 Days | 5 GB / 30 Days | 10 GB / 30 Days |
|---|---|---|---|
| Argentina | ~$8 | ~$12 | ~$21 |
| Brazil | ~$9 | ~$13 | ~$22 |
| Chile | ~$7 | ~$11 | ~$20 |
| Colombia | ~$11 | ~$14 | ~$25 |
| Peru | ~$9 | ~$15 | ~$26 |
| Bolivia | ~$19 | ~$27 | ~$46 |
Prices shown in USD, approximate at time of writing. Check current pricing for exact rates.
Option 2: Latin America Regional eSIM (LATAM Travellers) — NEW
LATAM Travellers now offers a regional eSIM plan covering 17 Latin American countries with a single eSIM. Like our individual country plans, it is delivered digitally with instant activation. The key difference: one eSIM works seamlessly across borders — no switching required.
Prices as of March 2026.
Pricing starts from $8.33 for 1 GB / 7 days, making it one of the most affordable regional options available. Larger plans offer even better value per GB. Because it is from LATAM Travellers, you get the same specialist support, instant delivery, and regional expertise as our country-specific plans.
Ideal for: Travellers visiting 3 or more countries who want the convenience of a single plan at a competitive price — without paying the premium of unlimited plans.

Option 3: Regional Plan (Airalo LatamLink)
Airalo's LatamLink plan covers 18 Latin American countries with a single eSIM. You install it once and it works across borders automatically -- no switching required. At time of writing, plans start at around $5 for 1 GB and go up to roughly $42 for 20 GB. For a deeper look at exactly what LatamLink includes and does not include, see our Airalo LatamLink review.
Option 4: Unlimited Data Plan (Holafly)
Holafly offers unlimited data plans for several individual South American countries, though their regional coverage is more limited. Plans are time-based rather than data-based, starting at around $19 for 5 days up to roughly $69 for 30 days, at time of writing. There is a fair-use throttling policy after heavy usage. Read our Holafly Latin America review for the full details on what "unlimited" actually means in practice.
Itinerary Cost Breakdowns: Real Prices Compared
The only way to choose the right eSIM approach is to calculate the actual cost for your specific itinerary. Here are three popular South America routes with real pricing as of March 2026.
Classic Backpacker Route: Colombia, Peru, Bolivia, Argentina (4 Weeks)
This is the most popular multi-country South America itinerary, typically done over 4-6 weeks. You will need reliable data in each country for maps, translation, and booking onward transport. All costs below are in USD, approximate at time of writing.
| Approach | What You Get | Total Cost | Convenience |
|---|---|---|---|
| LATAM Travellers (4 individual plans) | 3 GB per country (12 GB total) | ~$47 | Switch eSIM at each border |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| Airalo LatamLink (1 regional plan) | 10 GB shared across all countries | ~$26 | One plan, no switching |
| Holafly (30-day unlimited) | Unlimited (throttled after heavy use) | ~$69 | One plan, no switching |
All prices in USD, approximate at time of writing. Competitor pricing changes frequently -- verify on their websites before purchasing.
Verdict: For the classic 4-country route, Airalo LatamLink offers a strong balance of price and convenience if 10 GB is enough for your trip. LATAM Travellers gives you more total data (12 GB vs 10 GB) but costs more and requires switching at borders. Holafly is the premium option if you need unlimited data and do not want to think about usage.
Pro Tip: Bolivia has noticeably higher eSIM costs than its neighbours. If your itinerary is flexible, using WiFi more heavily in Bolivia and saving your data budget for countries where connectivity is cheaper can reduce your overall costs significantly.
Two-Country Trip: Brazil + Argentina (2 Weeks)
A two-week Brazil-Argentina trip is one of the most common South American itineraries, typically combining Buenos Aires, Iguazu Falls, and Rio de Janeiro or Sao Paulo. All costs below are in USD, approximate at time of writing.
| Approach | What You Get | Total Cost | Convenience |
|---|---|---|---|
| LATAM Travellers (2 individual plans) | 3 GB per country (6 GB total) | ~$17 | Switch once at the border |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| Airalo LatamLink (1 regional plan) | 5 GB shared | ~$16 | One plan, no switching |
| Holafly (15-day unlimited) | Unlimited (throttled after heavy use) | ~$47 | One plan, no switching |
All prices in USD, approximate at time of writing.
Verdict: For a two-country trip, individual eSIMs from LATAM Travellers and Airalo LatamLink are very close in price, but individual plans give you 20% more data. With only one border crossing to manage, the convenience advantage of a regional plan is minimal. Holafly only makes sense here if you are a very heavy data user.
Patagonia Circuit: Chile + Argentina (3 Weeks)
Patagonia travellers often cross between Chile and Argentina multiple times -- Torres del Paine to El Chalten, Punta Arenas to Ushuaia. This is where eSIM approach matters most because you may cross the border three or four times. For budgeting the rest of your Patagonia trip, see our Patagonia travel costs guide. All costs below are in USD, approximate at time of writing.
| Approach | What You Get | Total Cost | Recommended For |
|---|---|---|---|
| LATAM Travellers (2 individual plans) | 5 GB per country (10 GB total) | ~$24 | Budget-conscious travellers willing to toggle |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| LATAM Travellers Regional (1 plan, NEW) | Shared across 17 countries | From ~$8 | One plan, no switching |
| Airalo LatamLink (1 regional plan) | 10 GB shared | ~$26 | Frequent border crossers |
| Holafly (15-day unlimited) | Unlimited (throttled after heavy use) | ~$47 | Heavy data users, remote workers |
All prices in USD, approximate at time of writing.
Verdict: The Patagonia circuit is where regional plans genuinely shine. Crossing the Chile-Argentina border three or four times means toggling your eSIM repeatedly with individual plans. LatamLink at around $26 is only $2 more than the individual plan approach and eliminates the hassle entirely. LATAM Travellers still offers a lower per-GB price if you do not mind switching.
How to Decide: Individual vs Regional vs Unlimited
The right eSIM approach for South America comes down to three factors: how many countries you are visiting, how much data you use, and how much you value convenience over savings.
| Factor | Individual Plans | LATAM Regional (NEW) | Regional Plan (Airalo) | Unlimited Plan | |
|---|---|---|---|---|---|
| Cost per GB | Lowest | Low-Medium | Medium | Highest (but unlimited) | |
| Convenience | Switch at each border | One plan, no switching | One plan, no switching | One plan, no switching | One plan, no switching |
| Best for 1-2 countries | Strong choice | Good if low data needed | Overpaying slightly | Usually overpaying | |
| Best for 3-4 countries | More effort, similar cost | Best value | Strong choice | Premium option | |
| Best for 5+ countries | Manageable but tedious | Best value | Strong choice | Strong choice | |
| Data-heavy users | Buy larger plans per country | Pick a larger plan size | May run out mid-trip | No data anxiety | |
| Flexible itinerary | Buy as you go | Already covered (17 countries) | Already covered | Already covered |
Pro Tip: You can combine approaches. Use a regional LatamLink plan as your baseline, and add an individual LATAM Travellers country eSIM for the country where you will spend the most time. This gives you seamless cross-border coverage with extra data where you need it most.
Practical Guide: Managing Multiple eSIMs on Your Phone
Modern iPhones and Android phones can store far more eSIM profiles than most travellers realise, making the multi-eSIM approach completely practical for South America.
How Many eSIMs Can Your Phone Store?
- iPhone 13 and later: Up to 8 eSIM profiles stored simultaneously
- iPhone 15 Pro and later: Up to 8 active eSIMs (no physical SIM tray on US models)
- iPhone 16 series: Up to 20+ eSIM profiles
- Samsung Galaxy S24/S25: Up to 5 eSIM profiles
- Google Pixel 8/9: Up to 8 eSIM profiles
Even for a 6-country South America trip, you will not run out of eSIM slots on any recent phone.
How to Switch Between eSIMs at a Border
On iPhone:
- Open Settings > Cellular (or Mobile Data)
- Tap the eSIM for your new country
- Toggle Turn On This Line
- Set it as your data line under Cellular Data
- Make sure Data Roaming is ON
On Android:
- Open Settings > Network & Internet > SIMs
- Tap the new country's eSIM
- Toggle it on and set as preferred for mobile data
- Enable Roaming if prompted
The whole process takes under a minute. You can do it on the bus while crossing the border.
How Much Data Do You Actually Need?
| Usage Level | Weekly Usage | Typical Activities | Recommended Plan |
|---|---|---|---|
| Light | 500 MB - 1 GB | Maps, messaging, occasional photos | 1 GB / 7 days per country |
| Moderate | 1 - 3 GB | Social media, ride apps, video calls | 3 GB / 15 days per country |
| Heavy | 3 - 5 GB | Streaming, remote work, hotspot sharing | 5-10 GB / 30 days per country |
Most backpackers and tourists fall into the moderate category. Using WiFi at hostels and restaurants for heavy downloads (syncing photos, streaming) and mobile data for on-the-go needs is the most cost-effective approach. Use Meili, our free AI travel planner, to map out your itinerary and estimate how many days you will spend in each country -- that helps you pick the right plan size.
Coverage Gaps to Know About
No eSIM provider offers perfect coverage across South America, and being honest about where signal drops out helps you plan better than any marketing claim. These coverage notes apply to all providers equally since they all depend on the same local mobile networks.
- Bolivia: Coverage outside major cities (La Paz, Santa Cruz, Cochabamba) can be patchy. Rural areas and the Salar de Uyuni itself typically have limited or no signal
- Peru: Reliable coverage in Lima, Cusco, and along the coast. The Sacred Valley and Machu Picchu area have improving but inconsistent coverage
- Patagonia (Chile and Argentina): Major towns have coverage but remote hiking areas, including sections of the Torres del Paine W Trek, may have no signal
- Amazon regions: Coverage drops significantly in jungle areas across all countries. Download offline maps before heading into the Amazon
LATAM Travellers works with major local carriers in each country to provide the widest available coverage, but no provider can overcome the physical limitations of mobile infrastructure in remote areas.
Frequently Asked Questions
Can I use one eSIM for all of South America?
Prices as of March 2026.
Yes. LATAM Travellers now offers a Latin America regional eSIM covering 17 countries with a single plan, starting from just $8.33. Airalo LatamLink is another option covering 18 countries. For 1-2 countries with higher data needs, individual country plans may still be more cost-effective per GB.
Is it worth buying individual eSIMs for each country?
Yes, if you are visiting 1-3 countries and want the lowest price per GB. The savings are most significant for longer stays in each country. For quick transits through 4+ countries, a regional plan is usually simpler and comparably priced.
Do I need to delete one eSIM before installing another?
No. Modern phones can store multiple eSIM profiles simultaneously. You simply toggle between them in your phone settings. Install all your eSIMs at home before your trip while you have reliable WiFi.
Will my WhatsApp still work when I switch eSIMs?
Yes. WhatsApp is tied to your phone number, not your data plan. As long as you have an active data connection from any eSIM, WhatsApp works normally. Keep your home SIM active (even without data) to receive verification codes if needed.
What if I change my itinerary mid-trip?
This is where individual eSIMs have an advantage. You can purchase a new country eSIM from LATAM Travellers in minutes, anywhere with WiFi. With a regional plan, you are already covered. With Holafly, you may need to buy an additional country-specific plan if your new destination is not included.

Plan My TripThe Bottom Line
Prices as of March 2026.
There is no single answer to which eSIM is the right choice for South America -- it depends entirely on your itinerary. For two-country trips, individual plans from LATAM Travellers typically offer a lower cost with minimal inconvenience. For three or more countries, our new Latin America regional eSIM (covering 17 countries from $8.33) now offers a strong balance of price, convenience, and specialist support. Airalo LatamLink remains a solid alternative. And for heavy data users who do not want to think about gigabytes at all, Holafly's unlimited plans provide peace of mind at a premium price.
Whichever approach you choose, the most important step is installing your eSIM before you leave home. LATAM Travellers delivers all eSIMs digitally with instant activation, so you can set up while still connected to your home WiFi. As a Latin America connectivity specialist covering 22 countries, we focus exclusively on this region to provide competitive pricing and reliable coverage where you need it.
