The weekend or the trade trip
Macau is a special administrative region of China, 33 km² of dense reclamation around the Macau Peninsula, Taipa, Cotai, and Coloane. Most travelers arrive by ferry from Hong Kong's Sheung Wan or Sky Pier, by the HZMB (Hong Kong–Zhuhai–Macau Bridge) bus, or fly into MFM directly. The trip is usually a weekend — the casinos on Cotai, the Senado Square crowds, the Portuguese-era streets — or a few days for a gaming-industry conference. Connectivity has to work from the moment you reach immigration, not from a SIM kiosk you don't have time to find.
Roamzy charges $4.71 per gigabyte in Macau, billed in real time at $0.0046 per megabyte. No subscription. No expiry on the unused balance. 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 uses 0.7–1.2 GB per day: ride-hail, the camera-translator on a Cantonese sign, video calls home, the casino's app for shows and reservations, contactless payment integration, the mapping app for the dense Cotai grid. Call it 1 GB/day:
| Trip length | Roamzy ($4.71/GB) | Tourist roaming pass | Local SIM at MFM |
|---|---|---|---|
| Weekend (2 days) | $9.42 | $15–35 | $10–25 + 20 min at the counter |
| 5 days (conference) | $23.55 | $30–80 | $15–30 + KYC |
| 2 weeks | $65.94 | $70–160 (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 SIM at MFM or at the Hong Kong ferry terminal in Sheung Wan is sold but it's another counter, another passport, another window — and the ferry ride itself is fast enough that you'd be on the Macau side before you'd finished the form. The eSIM is already attached at the Outer Harbour terminal.
What works across the territory
Macau is one of the most densely covered places on Earth — a peninsula and three connected islands the size of a mid-sized European city, served by a Chinese-grade telecom infrastructure:
- Macau Peninsula (Senado Square, Inner Harbour, Outer Harbour) — 5G at 95%+, multiple operators, throughput stable
- Taipa and Cotai (the casino strip) — 5G across the resorts; signal in the underground gaming floors is good
- Coloane (Hac Sa, the village) — solid LTE in the village, weaker on the trail to the upper viewpoints
- The Macau Light Rapid Transit (LRT) — continuous signal on the elevated track
- The HZMB bus crossing to Hong Kong — the eSIM hands over networks at the border; brief gap as it switches
- Ferry to Hong Kong — partial 4G at sea on calmer days, gaps in the strait
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 flips on the second top-up. No fine-print throttling that surfaces during a video call. No auto-renewal you forgot to cancel after a weekend trip.
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?
Macau is rarely a standalone trip. The natural pairings:
- Hong Kong — the ferry, the bridge, the bus; the eSIM hands over networks at the border
- Mainland China — Zhuhai is on the other side of the border crossing at Gongbei
