Paraguay isn't the headliner, and the data pricing reflects that
Travelers heading through this part of South America usually frame the trip around Argentina and Brazil. Paraguay sits between them and gets fewer stops on the headline tour. That keeps tourist-tariff inflation lower here than at the Iguazú or Patagonia entry points — and it shows up in the wholesale data rate, which is one of the lowest we offer in the South America zone. The country's network is competitive, the rate is competitive, and the only thing standing between you and the network is whether you arrive with a tariff that just works.
Roamzy charges $2.97 per gigabyte in Paraguay. That's $0.0029 per megabyte, billed in real time as your phone uses data on Paraguayan networks. No subscription. No expiry on the unused balance. One per-MB rate across 192 countries is the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
Visitor patterns are predictable: Asunción for a few days, the Jesuit ruins in the south, sometimes Encarnación for the Carnival or the bridge to Argentina. Cellular usage is moderate — around 0.7–1 GB/day:
| Trip length | Roamzy ($2.97/GB) | Tourist roaming pass | Local SIM at ASU |
|---|---|---|---|
| 3 days | $8.91 | $15–35 | $8–20 + paperwork |
| 1 week | $20.79 | $30–70 | $15–30 + 30-day cap |
| 2 weeks | $41.57 | $60–140 (often two passes) | $25–45 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A local SIM at Silvio Pettirossi (ASU) is workable for a longer stay. For a typical week-long trip the math is comparable, and the eSIM removes the queue.
Where is Roamzy reliable, and where isn't it?
- Asunción, Ciudad del Este, Encarnación — solid 4G/LTE, 5G in central Asunción
- The Asunción–Encarnación route via Route 1 — workable LTE in populated stretches
- Jesuit ruins (Trinidad, Jesús de Tavarangue) — 4G near the towns; the ruins themselves are signal-light at edges
- The Chaco (western Paraguay) — sparse cellular; very long stretches without signal toward the Bolivian border
- Itaipu dam area near Ciudad del Este — solid 4G
- The river towns along the Paraguay and Paraná — workable 4G in towns, weaker on water
If you're crossing into the Chaco for the Mennonite colonies or heading to the Bolivian border, treat cellular as a bonus rather than a guarantee. Offline maps cover most of it.

What are Roamzy's honest limitations?
Three traps Roamzy doesn't have, because they were never built in.
- No welcome promo that flips on the second top-up. Top-up #1 and top-up #20 cost the same per megabyte.
- No fine-print throttling halfway through the week. One rate, full speed.
- No auto-renewal you forgot to cancel after flying back. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip extends across the region?
- Argentina — south across the Paraná into Posadas or Buenos Aires
- Brazil — east via the Ciudad del Este–Foz do Iguaçu bridge
- Bolivia — northwest through the Chaco
