Portugal is small and well wired. The math is small too.
Portugal fits roughly inside the state of Indiana. A typical trip moves Lisbon → Sintra → Évora → Faro → Porto over two weeks and never crosses 600 km of driving. That's a sample-size problem in disguise: the data load on a Portuguese trip is genuinely modest, which makes per-megabyte billing look exactly right and a 5 GB tourist pass look exactly wrong.
Roamzy charges $1.43 per gigabyte in Portugal. That's $0.0014 per megabyte, billed in real time as your phone uses data on Portuguese networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 192 countries — that's the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor to Portugal uses 0.5–1.2 GB per day: Maps in Alfama and through the tile-clad streets of Porto, Bolt for the hill rides, the camera-translator on a tasca menu, the CP train app for Lisbon–Porto, Glovo for late dinner, contactless payments via Apple Pay or Google Pay (MB WAY is the local QR system, but most foreign cards work everywhere). Call it 1 GB/day for the math:
| Trip length | Roamzy ($1.43/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $4.30 | $15–40 | $10–25 + paperwork |
| 1 week | $10.00 | $25–60 | $15–30 + paperwork |
| 2 weeks | $20.00 | $40–100 (often two passes) | $20–35 + 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.
An airport SIM at LIS, OPO, or FAO is straightforward but it's still a queue, a passport, and a 30-day expiry on whatever bundle you didn't use. eSIM removes the kiosk visit.
Where does Roamzy work in this country?
Portugal is one of the better-wired EU markets. The shape on the ground:
- Lisbon, Porto, Faro, Coimbra, Braga — 5G in the centers, providers compete on quality
- The Algarve coast (Albufeira, Lagos, Tavira, Sagres) — solid LTE through the resort towns
- Alentejo and the Douro Valley — workable LTE in towns, weaker on rural roads between vineyards
- Sintra, Cascais, Óbidos — strong LTE, 5G near the city centers
- Madeira (Funchal and the south coast) — solid LTE; mountain interior drops
- The Azores (São Miguel, Terceira, Pico) — workable LTE in towns, weaker on hiking trails
- CP intercity (Lisbon–Porto, Lisbon–Faro) — near-continuous signal end to end
Why is per-megabyte pricing simpler than packages?
A Portugal trip is already a stack of small frictions: trams that don't run when you'd expect, museum tickets that need an online slot, a card your bank flagged on the third pastel de nata. 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?

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 $0.0014/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 to other countries?
Portugal pairs naturally with Spain, and many travelers loop through both. Same Roamzy account, same logic at the border:
- Spain — overland from Porto via Vigo or from Faro via Seville, separate country rate
- Morocco — eSIM hands over at the border without you touching anything; the ferry from Tarifa or a short flight from Lisbon both work the same way
