Spain has the network. The trap is everything else.
Spain is one of the most wired countries in the EU — top-five for 5G coverage, dense LTE across rural Andalusia and the Pyrenees, working signal in the Madrid metro. The network isn't the problem. The problem is what sits between you and the network: a roaming pass priced for fear, an airport SIM kiosk that wants your passport and forty minutes, or a "tourist plan" with a 5 GB cap printed in 6-point type.
Roamzy charges $1.43 per gigabyte in Spain. That's $0.0014 per megabyte, billed in real time as your phone uses data on Spanish networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 192 countries — that's not a marketing line, it's the shape of the invoice.
How much will Roamzy actually cost on this trip?
A typical visitor to Spain burns 0.5–1.5 GB per day: Google or Apple Maps to the hotel, the camera-translator on a tapas menu, Bolt or Cabify across the city, the RENFE app for AVE high-speed trains, Glovo for late-night food, contactless payments through your bank app, the occasional video call home. 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 | $20–55 | $15–30 + paperwork |
| 2 weeks | $20.00 | $35–95 (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 €15–30 looks fine until you read what's bundled. Show passport, sit through KYC, take a number on a tourist tariff that's usually pricier than the same network sells locals, then pay in cash or with a Spanish card. An hour in line at Barajas or El Prat in July is normal. eSIM skips the lot: you land, the counter starts ticking, you walk out.
Why is per-megabyte pricing simpler than packages?
Travel is already cognitive load. Connections, an unfamiliar language, a card your bank silently flagged. Connectivity should be the one thing that just works.
Roamzy is built around that. No first-purchase promo to lure you, then jacked rates on the second top-up. No fine-print throttling — "5 GB at full speed, then 128 kbps." No auto-renewal you forgot to cancel and discover six months later. One rate, billed by the megabyte, balance carries. Spent 320 MB walking the Gothic Quarter? You paid $0.45. Today on hotel Wi-Fi using nothing? You paid nothing.
This isn't a feature, it's an engineering preference for not having features. You can't price below this without re-introducing the small print, so we don't.
Where does Roamzy work in this country?
Spain is an EU telecoms front-runner. Reality on the ground:
- Madrid, Barcelona, Valencia, Seville — 5G at 95%+, providers compete on quality more than coverage
- Regional capitals (Bilbao, Málaga, Zaragoza) — solid LTE, 5G in central districts
- Balearics and Canaries — clean handover between islands, 4G/5G across resort zones
- AVE trains between cities — near-continuous signal end to end; brief drops in tunnel sections
- Madrid and Barcelona metros — working signal on platforms and in most tunnel runs
Mass cellular dead zones aren't really a Spanish problem. If you're trekking the Pyrenees or the Sierra Nevada high country, expect spotty 4G — GPS plus offline maps handle that.

Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What if my trip continues to other countries?
Roamzy is for the traveler, not the resident. The same rate logic applies the moment you cross a border:
- Portugal — same $1.43/GB, eSIM hands over without you touching a setting
- France — same price band, same billing model
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
