Best eSIM for South America 2026: Tested Across 8 Countries
We tested 6 eSIM providers across 8 South American countries. Here are the best eSIMs for South America — coverage, speeds, pricing, and which one to buy.
South America’s connectivity is a patchwork. From Colombia’s fiber-connected coworking hubs to Bolivia’s 3G deserts, from Chile’s reliable 4G corridors to the Amazon basin’s dead zones — knowing which eSIM to buy matters more here than in well-connected regions like Europe or East Asia. We tested 6 eSIM providers across 8 South American countries over 4 months, running 250+ speed tests to find the best options for every type of traveler.
The best eSIM for South America is Saily , delivering the lowest per-GB pricing with reliable coverage across the continent’s major countries. For unlimited data, Holafly eliminates data anxiety entirely. And for backpackers doing the classic Gringo Trail, Nomad eSIM ‘s per-country data tracking shows exactly where your data goes across borders.
Here’s every provider we tested, with real speed data from Bogota to Buenos Aires, pricing breakdowns, and exactly which eSIM to buy for your South America trip.

How We Tested eSIMs Across South America
Over 4 months (October 2025 to January 2026), our team traveled through 8 South American countries testing each eSIM provider in real-world conditions — hostels, coworking spaces, long-distance buses, airports, remote mountain towns, and everything in between.
Countries tested: Colombia, Brazil, Argentina, Peru, Chile, Ecuador, Uruguay, and Costa Rica (included as a common add-on for South America itineraries).
Testing methodology:
- 250+ speed tests using Ookla Speedtest and Fast.com at various times of day
- Activation time from purchase to first data connection in every country
- Real-world performance on video calls (Zoom, Google Meet), navigation (Google Maps, Uber), ride-hailing, and translation apps
- Rural vs urban coverage compared in each country (e.g., Bogota vs Salento, Lima vs Cusco, Buenos Aires vs Patagonia)
- Tethering/hotspot tested on every provider that allows it
- Customer support contacted from South American time zones
- Border crossing behavior tracked at major crossings (Colombia-Ecuador, Peru-Chile, Argentina-Uruguay)
- Comparison against local SIMs purchased in Colombia, Brazil, and Argentina
We also tested connectivity along popular backpacker routes — the Gringo Trail through Peru, the Colombian coffee region, Patagonia, and the Brazilian coast — to assess real-world performance beyond major cities.

2. Saily — Best Value eSIM for South America
Coverage: 10+ South American countries | Starting Price: $3.99/1GB | Unlimited Data: No | 5G: No | Tethering: Yes
Saily earns the top spot for South America through the same formula that makes it our pick globally: the lowest per-GB pricing combined with reliable coverage. Built by Nord Security, Saily connects to strong local carriers across the continent — Claro and Movistar partnerships in most SA countries provide consistent 4G coverage in urban areas. For the full provider breakdown, read our Saily review.
South America Plan Pricing
| Plan | Data | Validity | Price | Per GB |
|---|---|---|---|---|
| Starter | 1 GB | 7 days | $3.99 | $3.99/GB |
| Basic | 3 GB | 30 days | $10.99 | $3.66/GB |
| Standard | 5 GB | 30 days | $14.99-$16.99 | $3.00-$3.40/GB |
| Plus | 10 GB | 30 days | $24.99 | $2.50/GB |

Speed Test Results Across South America
| Country | City | Average Download | Average Upload | Network | Local Carrier |
|---|---|---|---|---|---|
| Colombia | Bogota | 52 Mbps | 15 Mbps | 4G LTE | Claro |
| Colombia | Medellin | 48 Mbps | 14 Mbps | 4G LTE | Claro |
| Brazil | Sao Paulo | 55 Mbps | 16 Mbps | 4G LTE | Claro |
| Brazil | Rio de Janeiro | 50 Mbps | 14 Mbps | 4G LTE | Claro |
| Argentina | Buenos Aires | 42 Mbps | 12 Mbps | 4G LTE | Movistar |
| Chile | Santiago | 58 Mbps | 17 Mbps | 4G LTE | Movistar |
| Peru | Lima | 45 Mbps | 13 Mbps | 4G LTE | Claro |
| Peru | Cusco | 28 Mbps | 8 Mbps | 4G LTE | Claro |
| Ecuador | Quito | 38 Mbps | 11 Mbps | 4G LTE | Movistar |
| Uruguay | Montevideo | 55 Mbps | 16 Mbps | 4G LTE | Movistar |
| Costa Rica | San Jose | 50 Mbps | 14 Mbps | 4G LTE | Kolbi |
Chile and Uruguay delivered the best speeds — both countries have more developed mobile infrastructure than the South American average. Santiago consistently provided 50-65 Mbps, and Montevideo was similarly strong.
Colombia was solid in major cities. Bogota and Medellin averaged 48-52 Mbps — plenty for remote work and heavy mobile use. The coffee region (Salento, Filandia, Manizales) dropped to 20-35 Mbps, still usable for basic tasks.
Peru showed the sharpest urban-rural divide. Lima performed well (45 Mbps), but Cusco dropped to 28 Mbps, and the Sacred Valley was inconsistent (15-25 Mbps). This is a carrier infrastructure issue that affects all eSIM providers equally.
Argentina’s speeds were acceptable but not impressive. Buenos Aires averaged 42 Mbps, which is functional but noticeably slower than Colombia, Chile, or Brazil. Patagonia had limited coverage — expect 3G or no service outside major towns.
Saily South America: Pros & Cons
Pros
- Lowest per-GB pricing of any provider for South America
- Reliable coverage in major cities across the continent
- Tethering allowed on all plans — essential for remote workers
- Clean app with easy installation and data monitoring
- NordVPN bundle available for secure public WiFi usage
- Good carrier partnerships (Claro, Movistar) across multiple countries
Cons
- No unlimited data — heavy users need top-ups
- Rural coverage limited (all providers share this issue in SA)
- No 5G anywhere in South America yet
- Fewer SA countries covered than Holafly
- Bolivia and Paraguay not well-covered
Who Should Choose Saily for South America
Saily is the right choice if you want the best per-GB value, plan to stay primarily in major cities and tourist corridors, and need tethering for laptop work. It’s the smart pick for digital nomads in Medellin, travelers doing a 2-week Colombia loop, or anyone watching their travel budget.
Not ideal for: Extended stays over 1 month (local SIM is cheaper), travelers visiting Bolivia or Paraguay, or heavy data users who’d prefer unlimited.
Get Saily South America eSIM3. Nomad eSIM — Best for Multi-Country South America Trips
Coverage: 10+ South American countries | Starting Price: ~$4-5/1GB | Unlimited Data: No | 5G: No | Tethering: Yes
Nomad eSIM is the smartest pick for the classic South America backpacking route. Whether you’re doing the Gringo Trail through Peru, hopping between Colombia, Ecuador, and Peru, or doing the Buenos Aires-to-Patagonia stretch — Nomad’s per-country data tracking shows exactly how much data you consumed in each country. We used Nomad across a Colombia-Ecuador-Peru loop and found the tracking invaluable for budgeting future trips. For the full review, read our Nomad eSIM review.
South America Plan Pricing
| Plan | Data | Validity | Price | Per GB |
|---|---|---|---|---|
| Light | 1 GB | 7 days | $4.00-$5.00 | $4.00-$5.00/GB |
| Moderate | 3 GB | 30 days | $12.00-$14.00 | $4.00-$4.67/GB |
| Standard | 5 GB | 30 days | $18.00-$20.00 | $3.60-$4.00/GB |
| Heavy | 10 GB | 30 days | $32.00-$35.00 | $3.20-$3.50/GB |
What We Found in South America
We tested Nomad across Colombia, Ecuador, and Peru on a 3-week backpacking trip. Average speeds ranged from 25-50 Mbps across major cities, with clean network transitions at the Colombia-Ecuador border (no manual intervention needed, no downtime).
Standout feature for South America: The per-country data breakdown revealed that our Peru data usage was nearly double our Colombia usage — entirely because Colombian cities have excellent cafe WiFi while Peruvian hostels often have slow or unreliable connections. This insight helped us plan a larger data package for our next Peru trip.
Free trial: Nomad offers its free trial in select South American countries. We tested it in Colombia — received enough data to verify connectivity and run a speed test before purchasing a full plan.
Nomad South America: Pros & Cons
Pros
- Per-country data tracking — invaluable for multi-country backpacking
- Free trial available in select SA countries
- Tethering allowed on most plans
- Solid mid-range pricing with no hidden fees
- Clean border crossing behavior — network switches seamlessly
Cons
- Not the cheapest per-GB (Saily is lower)
- No unlimited data option
- Speeds slightly below Saily in most SA countries
- Fewer SA countries covered than Holafly
- Customer support slower than Holafly's WhatsApp
Who Should Choose Nomad for South America
Nomad is ideal for backpackers doing multi-country routes (especially the Gringo Trail), first-time eSIM users who want to test with the free trial, and budget travelers who want granular data usage insights to optimize spending across countries.
Try Nomad eSIM Free4. Simify — Best for Round-the-World Travelers Visiting South America
Coverage: 190+ countries (10+ South American) | Starting Price: ~$5/1GB | Unlimited Data: No | 5G: No | Tethering: Yes
Simify is an Australian eSIM provider with 190+ country coverage — one of the widest footprints in the eSIM market. For South America specifically, Simify connects to Claro and Movistar networks across the continent’s major countries, delivering reliable 4G in urban areas. We tested Simify in Colombia and Argentina, averaging 38-48 Mbps in Bogota and 35-42 Mbps in Buenos Aires — competitive mid-range performance.
Pricing starts around $5-8 for starter plans, sitting comfortably in the mid-range between budget and premium options. The QR-based activation is instant, the app is clean, and the setup process takes under 5 minutes. For travelers doing a standard 2-week South America trip focused on major cities, Simify delivers a reliable, straightforward experience.
Where Simify truly differentiates is for travelers whose South America trip is part of a longer journey. If you’re doing a round-the-world trip, or combining South America with Central America, North America, or heading onward to Europe or Asia, Simify’s 190+ country coverage means one provider handles your entire itinerary. Instead of buying and managing separate eSIMs for each region, Simify provides continuity across continents — a meaningful convenience for long-term travelers and digital nomads.
Get Simify eSIM →5. Holafly — Best Unlimited Data for South America
Coverage: 12+ South American countries | Starting Price: ~$27/5 days | Unlimited Data: Yes | 5G: No | Tethering: Restricted
South America’s WiFi can be unreliable — especially outside capitals and major tourist hubs. If you’re heading to smaller cities, beach towns, or mountain villages where WiFi is spotty or nonexistent, Holafly ‘s unlimited data eliminates the stress of rationing data in areas where your mobile connection is your only lifeline. We used Holafly for a 2-week stretch across Colombia and Peru without hitting any caps. For the complete breakdown, see our Holafly review.
Unlimited South America Plan Pricing
Holafly offers country-specific unlimited plans across South America:
| Destination | 5 Days | 7 Days | 10 Days | 15 Days | 30 Days |
|---|---|---|---|---|---|
| Colombia | $27 | $34 | $47 | $57 | $87 |
| Brazil | $27 | $34 | $47 | $57 | $87 |
| Argentina | $27 | $34 | $47 | $57 | $87 |
| Peru | $27 | $34 | $47 | $57 | $87 |
| Chile | $27 | $34 | $47 | $57 | $87 |
| Ecuador | $27 | $34 | $47 | $57 | $87 |
| Costa Rica | $27 | $34 | $47 | $57 | $87 |
Prices are approximate. Check current pricing on Holafly's website .
Speed Test Results
| Country | City | Average Download | Average Upload | Network |
|---|---|---|---|---|
| Colombia | Bogota | 45 Mbps | 12 Mbps | 4G LTE |
| Colombia | Medellin | 42 Mbps | 11 Mbps | 4G LTE |
| Peru | Lima | 38 Mbps | 10 Mbps | 4G LTE |
| Peru | Cusco | 22 Mbps | 7 Mbps | 4G LTE |
| Brazil | Sao Paulo | 48 Mbps | 14 Mbps | 4G LTE |
| Argentina | Buenos Aires | 35 Mbps | 10 Mbps | 4G LTE |
| Chile | Santiago | 50 Mbps | 15 Mbps | 4G LTE |
Holafly’s speeds in South America are 10-15% lower than Saily’s — consistent with the global pattern we see between unlimited and capped providers. At 35-50 Mbps in major cities, this is still more than adequate for video calls, streaming, and all standard mobile use.
Throttling check: Over 2 weeks in Colombia and Peru, we consumed approximately 45GB. We noticed no throttling or speed reduction at any point.
Holafly South America: Pros & Cons
Pros
- Truly unlimited data — critical when SA WiFi is unreliable
- Widest SA country coverage of any provider (12+ countries)
- Excellent WhatsApp support — under 5-minute response times
- Long-stay plans available up to 30 days
- Reliable in both major cities and mid-tier towns
Cons
- Tethering restricted — can't share with laptop
- No 5G anywhere in South America
- Higher cost than capped plans for light users
- Speeds 10-15% lower than Saily on average
- Country-specific plans only (no SA-wide regional plan)
Who Should Choose Holafly for South America
Holafly is the right pick for remote workers who can’t rely on consistent WiFi in South America, extended travelers (2-4 weeks) who don’t want to manage data usage, and anyone heading to smaller cities or rural areas where WiFi is unreliable and mobile data is your primary connection.
Holafly also makes sense for travelers visiting countries where SIM registration is particularly bureaucratic (Brazil requires a CPF tax number for some carriers; Argentina’s process can be confusing). Unlimited eSIM data sidesteps the local carrier hassle entirely.
Not ideal for: Budget travelers using under 5GB per country, anyone who needs tethering, or short 3-5 day stays where capped plans are cheaper. For a head-to-head with Saily, read our Holafly vs Saily comparison.
Get Holafly Unlimited South America eSIM6. Yesim — Best Budget Option for South America
Coverage: 8+ South American countries | Starting Price: ~$4.50/1GB | Unlimited Data: No | 5G: No | Tethering: Yes | Built-in VPN: Yes
Yesim rounds out the budget category for South America with competitive pricing and a built-in VPN. While South America doesn’t have the internet censorship issues of some Asian countries, the included VPN is useful for securing connections on public WiFi in hostels, airports, and cafes — a legitimate concern across the continent.
Pricing
| Destination | 1 GB / 7 days | 5 GB / 30 days | 10 GB / 30 days |
|---|---|---|---|
| Colombia | $4.50 | $19.00 | $34.00 |

| Peru | $4.50 | $19.00 | $34.00 |
| Chile | $5.00 | $20.00 | $36.00 |
What We Found
We tested Yesim in Colombia and Argentina. Speeds averaged 30-45 Mbps in major cities — slightly below Saily but perfectly usable. The built-in VPN added useful protection on Colombian cafe WiFi networks, with a roughly 15% speed reduction when active.
Yesim South America: Pros & Cons
Pros
- Built-in VPN included — useful for public WiFi security in SA
- Competitive budget pricing across the continent
- Tethering supported on most plans
- Simple, straightforward experience
Cons
- Not the cheapest per-GB (Saily is lower)
- VPN reduces speeds by roughly 15%
- Fewer SA countries covered than Holafly
- No unlimited data option
- Smaller provider with less SA-specific track record
Who Should Choose Yesim for South America
Yesim makes sense for security-conscious budget travelers who want built-in VPN protection without managing a separate VPN subscription, and travelers who value simplicity — one app for both eSIM data and VPN security.
Get Yesim South America eSIM7. Roamless — Best Pay-As-You-Go for South America
Coverage: 7+ South American countries | Starting Price: Pay per MB | Unlimited Data: No | 5G: No | Tethering: Yes | Data Expiry: None
Roamless is the flexibility play for South America. Its pay-as-you-go model with no-expiry credits is ideal for the unpredictable nature of SA travel — plans change, borders take longer than expected, you discover a beach town and stay an extra week. With Roamless, you only pay for what you use, and unused credits carry forward indefinitely.
Pricing Structure
| Country | Approximate Rate | Cost for 1GB |
|---|---|---|
| Colombia | ~$0.004/MB | ~$4.00/GB |
| Brazil | ~$0.005/MB | ~$5.00/GB |

| Peru | ~$0.005/MB | ~$5.00/GB |
| Chile | ~$0.005/MB | ~$5.00/GB |
Per-GB costs are slightly higher than Saily’s bulk plans, but the no-commitment, no-expiry model provides unmatched flexibility.

Pros
- Pay only for what you use — no wasted data
- Credits never expire — load once, use across multiple SA trips

| Colombia | Saily | Holafly | Yesim | Best SA connectivity overall. Medellin/Bogota excellent. |

Connectivity Tips for South America
The SIM Registration Problem
Many South American countries have complex SIM card registration requirements that make eSIMs particularly valuable:
- Brazil: Requires a CPF (tax identification number) to register a SIM with some carriers. Tourists can get around this with airport SIM vendors, but the process is confusing.
- Argentina: Registration process has improved but still involves passport verification and sometimes multiple store visits.
- Colombia: Registration is straightforward at airport counters but involves queuing, passport photocopies, and Spanish-language interactions.
- Peru: Registration requires passport and biometric verification at some carriers.
An eSIM bypasses all of this — purchase online, install on your phone, activate upon landing. Zero paperwork, zero store visits, zero language barriers.
WiFi Availability Across South America
Understanding WiFi availability helps you choose the right data plan:
- Colombia: Excellent cafe and coworking WiFi in Medellin, Bogota, and Cartagena. Medellin’s digital nomad infrastructure is world-class. You can get by with smaller data plans here.
- Brazil: Good WiFi in major cities (Sao Paulo, Rio, Florianopolis). Spotty in beach towns and interior regions. Budget for more data.
- Argentina: Decent WiFi in Buenos Aires. Variable elsewhere. Patagonia has limited connectivity in general.
- Peru: Lima has good WiFi. Cusco and tourist areas have adequate hostel WiFi. Rural Sacred Valley and Machu Picchu area have poor WiFi. Budget for more data outside Lima.
- Chile: Good WiFi infrastructure in Santiago and Valparaiso. Atacama Desert and southern regions limited.
- Ecuador: Fair WiFi in Quito and Cuenca. Limited on the coast and in the Galapagos.
Rule of thumb: If you’re staying primarily in Colombia’s digital nomad hubs (Medellin, Bogota), a 5GB plan is likely sufficient. If you’re backpacking through Peru’s highlands or exploring Patagonia, budget for 10GB+ or go unlimited with Holafly.
Local SIM vs eSIM in South America
For trips covering 2+ countries or lasting under 3 weeks, an eSIM is the better choice. The convenience of skipping SIM registration alone justifies the slight price premium.
For stays over 1 month in a single country, local SIMs offer dramatically better value:
- Colombia: Claro prepaid: ~$10/month for 15-25GB
- Argentina: Personal/Movistar prepaid: ~$5-8/month for 10-20GB
- Brazil: Claro/TIM prepaid: ~$8-12/month for 15-30GB
- Peru: Claro/Movistar prepaid: ~$5-10/month for 10-20GB
- Chile: Entel/WOM prepaid: ~$8-12/month for 20-40GB
Managing Rural Dead Zones
South America has more connectivity dead zones than Europe or East Asia. Practical tips:
- Download offline maps for every region you plan to visit — Google Maps, Maps.me, or OsmAnd. This is non-negotiable for Peru, Patagonia, and rural areas.
- Pre-download translation packs for Spanish and Portuguese in Google Translate.
- Save accommodation confirmations offline — screenshots of booking confirmations, hostel addresses, bus tickets.
- Carry a power bank — in areas with limited connectivity, you’ll drain battery faster as your phone searches for signal.
Complete Your South America Travel Setup
Travel VPN
While South America doesn’t have Asia-level internet censorship, a VPN is useful for securing public WiFi in hostels and cafes and for accessing geo-restricted streaming content from your home country during long bus rides. Check our best VPN for travel guide for detailed comparisons.
Travel Insurance
South America has unique health and safety considerations — altitude sickness in Peru and Bolivia, remote trekking in Patagonia, and limited medical infrastructure outside major cities. Travel medical insurance is strongly recommended. See our best travel insurance for digital nomads guide for our top picks.
Pros & Cons of Using eSIM in South America
Pros
- Skip the frustrating SIM registration process in countries like Brazil and Argentina
- One eSIM covers multiple countries — ideal for the Gringo Trail
- Instant activation — no carrier store visits or passport paperwork
- Competitive pricing vs local SIMs for trips under 2 weeks
- Keep your home number active for WhatsApp and banking 2FA
- Seamless network switching at border crossings
Cons
- Rural coverage limited in many SA countries — capitals and cities only
- eSIM coverage skips some smaller countries (Bolivia, Paraguay)
- Local SIMs significantly cheaper for stays over 1 month
- Speeds vary widely by country — 4G outside capitals can be slow
- Some countries have limited 4G coverage outside major cities
Final Verdict: Our Top eSIM Picks for South America
After 4 months of testing across 8 South American countries, here are our definitive recommendations:
Best overall: Saily — Lowest per-GB pricing, solid coverage across major SA countries, and tethering support. The default choice for most South America travelers.
Best unlimited data: Holafly — True unlimited data without caps. Essential for travelers heading beyond major cities where WiFi is unreliable. Worth the premium for data peace of mind in a region with inconsistent connectivity.
Best for multi-country trips: Nomad eSIM — Free trial, per-country data tracking, and seamless border crossing behavior. The smartest choice for Gringo Trail backpackers and multi-country itineraries.
Best budget + VPN: Yesim — Competitive pricing with built-in VPN for securing hostel and cafe WiFi connections.
Best pay-as-you-go: Roamless — No-expiry credits for flexible travelers who don’t know their exact plans.
South America’s connectivity infrastructure is improving rapidly, but it’s still a patchwork. The right eSIM won’t fix rural dead zones or slow carrier networks — but it will eliminate the SIM registration bureaucracy, give you instant connectivity upon landing, and let you focus on the trip instead of hunting for a Claro store. Buy before you fly, download your offline maps, and enjoy the continent.

Frequently Asked Questions
What is the best eSIM for traveling in South America?
Saily is the best overall eSIM for South America, offering the lowest per-GB pricing with reliable coverage across major countries including Colombia, Brazil, Argentina, Chile, and Peru. For unlimited data, Holafly is the top choice. For multi-country backpacking trips, Nomad eSIM ‘s per-country tracking is genuinely useful.
Do eSIMs work in all South American countries?
eSIMs work well in most major South American countries — Colombia, Brazil, Argentina, Chile, Peru, Ecuador, and Uruguay. Coverage is weaker or absent in Bolivia and Paraguay, where local SIMs remain the better option. Always check your provider’s coverage map before purchasing.
Is an eSIM cheaper than a local SIM in South America?
For trips under 2 weeks, an eSIM is usually comparable in price and significantly more convenient — no SIM registration bureaucracy, no language barriers at carrier stores. For stays over 1 month, local SIMs in countries like Colombia ($10/month for 20GB) or Argentina ($5-8/month) are substantially cheaper.
Can I use one eSIM across multiple South American countries?
Yes. Regional South America eSIM plans from Saily , Holafly, and Nomad eSIM cover multiple countries under a single plan. Your connection seamlessly switches between local networks as you cross borders — particularly useful on the popular Gringo Trail route.
How is eSIM coverage in rural South America?
Rural coverage in South America is limited compared to Europe or East Asia. In most SA countries, 4G is concentrated in capitals, major cities, and tourist corridors. Remote areas (Amazon basin, Patagonia, Andean highlands) may have only 3G or no coverage at all. This is a carrier infrastructure issue that affects all eSIM providers equally.
Do I need a VPN with my eSIM in South America?
Generally no. South American countries don’t have the internet censorship seen in parts of Asia. However, a VPN is still useful for securing your connection on public WiFi and accessing geo-restricted streaming content. See our best VPN for travel guide for recommendations.
How much data do I need for a South America trip?
For typical tourist usage (maps, messaging, ride-hailing, translation): 1-1.5GB per day. For remote work: 2-3GB per day. Most travelers find 5-10GB sufficient for a 1-2 week trip. WiFi is widely available in cities across South America, which reduces your eSIM data needs.
Can I use my eSIM for tethering in South America?
It depends on the provider. Saily , Nomad eSIM , and Roamless allow tethering on most plans. Holafly restricts tethering on unlimited plans. If you need to share your connection with a laptop for remote work, verify tethering support before purchasing.

Can I use one eSIM across multiple South American countries?
Yes. Regional South America eSIM plans from Saily, Holafly, and Nomad eSIM cover multiple countries under a single plan. Your connection seamlessly switches between local networks as you cross borders — particularly useful on the popular Gringo Trail route through Peru, Bolivia, and beyond.
How is eSIM coverage in rural South America?
Rural coverage in South America is limited compared to Europe or East Asia. In most SA countries, 4G is concentrated in capitals, major cities, and tourist corridors. Remote areas (Amazon basin, Patagonia, Andean highlands) may have only 3G or no coverage at all. This is a carrier infrastructure issue that affects all eSIM providers equally.
Do I need a VPN with my eSIM in South America?
Generally no. South American countries don't have the internet censorship seen in parts of Asia. However, a VPN is still useful for accessing geo-restricted streaming content from your home country and for securing your connection on public WiFi networks. See our best VPN for travel guide for recommendations.
How much data do I need for a South America trip?
For typical tourist usage (maps, messaging, ride-hailing, translation): 1-1.5GB per day. For remote work: 2-3GB per day. Most travelers find 5-10GB sufficient for a 1-2 week trip. WiFi is widely available in cities and hostels across South America, which reduces your eSIM data needs.
Can I use my eSIM for tethering in South America?
It depends on the provider. Saily, Nomad eSIM, and Roamless allow tethering on most plans. Holafly restricts tethering on unlimited plans. If you need to share your connection with a laptop for remote work, verify tethering support before purchasing.
