HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall, with App 5.0/5 and Support 5.0/5, and prices fixed South America plans from $3.50/GB through its 204+ carrier partnerships, undercutting Airalo's $4.50/GB and Saily's $3.99/GB on a single-country booking even though it sells no continent-wide bundle to match Discover Global. Its Coverage score of 4.5 trails Airalo's 4.9, but its 186-country reach still covers an onward leg into Central America or the Caribbean without a second eSIM purchase.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo is the primary-listed provider on all 13 South America countries in this comparison and scores highest on Coverage at 4.9/5 on this scorecard, with its Discover Global bundle covering up to 130 countries on a single eSIM for travelers continuing beyond the continent. That breadth costs more per gigabyte at $4.50, the highest fixed rate among the five providers, a real gap against French Guiana's $0.90/GB floor and the region's $2.63/GB median.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Holafly -- Best Unlimited Daily Rate
Holafly's Pricing score reaches 4.5 with unlimited daily plans from $2.99/day, sold in 11 of this region's 13 countries, useful where the local per-GB floor runs high, such as Suriname's $5.97/GB. Fixed-data competitors price lower on trips to French Guiana or Venezuela, where the per-GB floor already sits under $1.50.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Saily -- Best for Privacy
Saily scores 4.4 on Network Generation, level with Airalo's joint-highest mark, and its bundled VPN carries less practical weight here than in other regions, since none of the 13 South America countries in this comparison restrict VPN access. Its $3.99/GB rate sits below Airalo's $4.50/GB but above HelloRoam's $3.50/GB, and its 200-country reach trails both for travelers adding a non-South America leg.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus
Nomad -- Best Budget Per-GB Rate
Nomad's discounted pricing tier concentrates in Southeast Asia, so its general $3.00/GB headline rate in South America lands between HelloRoam's floor and Airalo's ceiling rather than undercutting either. Its Support score of 3.9 is the lowest of the five providers in this comparison, with a 200-country reach behind only Airalo's, a relevant gap on routes into Guyana or Suriname's interior, where Digicel's infrastructure already faces coverage limits.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries

No. None of the 13 South America countries in this comparison restrict VPN access, a contrast to the Southeast Asia and Caribbean comparisons in this set, where several destinations carry exceptions.

HelloRoam scores 5.0/5 on our 2026 rubric on App, the highest App score among the five providers compared here. Airalo follows at 4.7/5 on the rubric, with Saily at 4.5/5 through its built-in VPN toggle. App quality affects e SIM data tracking and installation speed across South America, not network reach, which depends on Claro, Movistar, TIM, or Digicel per country.
