Three weeks of Brazil, one rate, no SIM swap between São Paulo and Salvador
A standard Brazil trip moves a lot. Fly into GRU, four nights in São Paulo, a domestic to GIG and a long weekend in Rio, then up to Salvador, then a flight inland to Manaus and a river boat. Four major cities, three regional carriers if you went local — three SIM swaps if you wanted decent rates in each. The eSIM bills at one Brazil rate from the moment you land at any of those airports. Three weeks. One number on the meter.
Roamzy charges $8.19 per gigabyte in Brazil. That's $0.0080 per megabyte, billed in real time as your phone uses data on Brazilian networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 192 countries — the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor to Brazil uses 0.6–1.5 GB per day: Maps in Rio's hill neighborhoods, 99 or Uber for everything (cabs without apps are a different genre), the camera-translator on a Portuguese menu, the LATAM or GOL app for domestic flights, iFood for delivery, contactless payments via Apple Pay or PIX (foreign cards have partial PIX integration), the occasional video call. Call it 1 GB/day for the math:
| Trip length | Roamzy ($8.19/GB) | Tourist roaming pass | Local SIM at GRU |
|---|---|---|---|
| 3 days | $24.58 | $25–55 | $10–25 + CPF or paperwork |
| 1 week | $57.34 | $45–100 | $15–35 + 30-day cap |
| 2 weeks | $114.69 | $80–180 (often two passes) | $25–50 + ID |
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.
Brazilian local SIMs require a CPF (a tax ID) for full activation in many cases. Foreign-friendly tourist tariffs exist, but they're sold at marked-up rates at airport kiosks with KYC paperwork. The eSIM avoids that.
Where does Roamzy work in this country?
Brazilian networks are extensive and have improved noticeably in the major cities, but the country is genuinely huge and rural coverage thins. The shape on the ground:
- São Paulo, Rio de Janeiro, Brasília, Belo Horizonte, Salvador — 5G in the centers, dense LTE through the metro areas
- Beach destinations (Florianópolis, Búzios, Porto de Galinhas, Jericoacoara) — solid LTE in resort zones
- Iguaçu, Foz, the Pantanal towns — workable LTE in the visitor zones; back-country drops
- Amazon (Manaus, the Anavilhanas, Mamirauá) — Manaus is fine; river travel runs out of signal between settlements
- Long highway drives across Bahia, Minas Gerais, Mato Grosso — patchy; offline maps mandatory
- Rio Metro and São Paulo Metro — signal works on platforms and most tunnel runs
Why is per-megabyte pricing simpler than packages?
A Brazil trip is already cognitive load: a payments stack that runs heavily on PIX (foreign card integration is partial), distances that are continent-scale even within one country, a card your bank flagged on the third caipirinha. The data plan should not also be a problem.
Roamzy is built around that. No first-purchase promo. No fine-print throttling. No auto-renewal six months later. One rate, billed by the megabyte, balance carries.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type N | 127/220 V (varies by city) | 60 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Top up the eSIM with a minimum of 20 USDT — stablecoins, no cards, no banks, no FX surcharges
- The QR code appears in the dashboard once payment confirms
- Settings → Cellular → Add eSIM → scan QR (do this before you fly)
- The counter starts the moment you land at GRU, GIG, BSB, SSA, or REC
Brazil uses Type N plugs and voltage varies between 127 V and 220 V depending on the city. Check your hotel — most accommodate both. 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 that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth cost the same $0.0080/MB.
- No auto-renewal you forgot to cancel. 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 continues across the continent?
South American trips often pair with neighbors:
- Argentina — frequent extension via the Buenos Aires hub, separate country rate
- Uruguay — eSIM hands over at the border without you touching anything, whether you take the Buquebus from Buenos Aires or drive south from Porto Alegre
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
