A small country with a coastline and an obvious data scenario
Uruguay is 176,000 km², 3.5 million people, and a capital — Montevideo — that holds roughly half of all residents. The trip pattern is narrow: a few nights in the capital, the drive east along Ruta Interbalnearia to Punta del Este or José Ignacio, maybe Colonia del Sacramento for a day before the ferry to Buenos Aires. That's the country a visitor sees, and it's well-wired for the visitor.
Roamzy charges $3.07 per gigabyte in Uruguay. That's $0.0030 per megabyte, billed in real time as your phone uses data on Uruguayan networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 193 countries is the sum of megabytes used, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor uses 0.7–1.2 GB per day: maps from Carrasco to the hotel, ride-hail across Pocitos and Ciudad Vieja, the bus app for the COT or Copsa schedule, messaging with the asado host who lives in WhatsApp like every Uruguayan. Call it 1 GB/day for the math:
| Trip length | Roamzy ($3.07/GB) | Tourist roaming pass | Local SIM at Carrasco |
|---|---|---|---|
| 3 days | $9.20 | $15–40 | $10–25 + ID and paperwork |
| 1 week | $21.50 | $30–80 | $15–30 + 30-day cap |
| 2 weeks | $43.00 | $70–140 (often two passes) | $20–35 + 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 Uruguayan SIM is sold at Carrasco airport and around Montevideo, but it's tied to your passport, a counter visit, and a 30-day window that expires whether you used it or not. The eSIM avoids the whole loop: you arrive, the counter starts ticking, you leave the airport already attached.
Where does Roamzy work in this country?
Uruguay is one of the better-wired countries in South America, and on a tourist's route the dead zones are rare:
- Montevideo, Pocitos, Ciudad Vieja, Punta Carretas — 4G/5G at 95%+, signal in the rambla and on the buses
- Punta del Este, La Barra, José Ignacio — solid LTE in the resort grid; weaker on the dunes and fishing villages further east
- Colonia del Sacramento — full LTE in the historic quarter and at the ferry terminal
- Ruta 9 to Cabo Polonio and Ruta 5 to Tacuarembó — continuous along the asphalt, thinner once you turn off
- The interior estancias — 4G in the towns, patchy on the rural roads, useable at the campo with line-of-sight
Cabo Polonio is the famous outlier: no road, no grid, signal exists but it's not the point of going there. Download maps and the boat-time before you ride the 4×4 in.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |

- The QR code appears in the dashboard once payment confirms
- Settings → Cellular → Add eSIM → scan QR (do this on home Wi-Fi before you fly)
- The counter starts the moment you land at Carrasco
Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in. No welcome promo on the first top-up that flips on the second. No fine-print throttling — "5 GB at full speed, then 128 kbps." No auto-renewal you forgot to cancel and discover six months later from a card you don't watch.
That's the whole pitch, really. Pay per megabyte in Uruguay, keep the balance forever, and notice there's no fine print for anyone to be cheaper than.
What if my trip continues to other countries?
Uruguay rarely travels alone. Most visitors arrive from Buenos Aires by ferry or stop on a Brazilian itinerary that runs Rio–Floripa–Punta. Same Roamzy logic applies the moment you cross:
- Argentina — the Buquebus from Colonia or Montevideo lands in Buenos Aires; the eSIM grabs the Argentine network on arrival
- Brazil — the road to Chuy and Porto Alegre, same per-MB billing model
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
