You land at Ivato, you load the map, you realize the next 18 hours are a road
Madagascar is the world's fourth-largest island — about 587,000 km² — with a road network that's older than its tourism boom and a coastline you can't actually drive. Most travelers fly into Antananarivo, then either fly internally to Nosy Be or Diego, or grind it out by 4×4 along the RN7 toward Tuléar. The connectivity story tracks that geography: cities and the main highway corridor have signal, the spaces between them often don't, and the "off-the-RN7" trips into the rainforest or down to Belo are real cellular dead zones.
Roamzy charges $5.73 per gigabyte in Madagascar. That's $0.0056 per megabyte, billed in real time as your phone uses data on Malagasy networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 193 countries is the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
Madagascar is a country where data discipline matters because the connection is uneven, not because the price is. You'll have signal in the city and in towns, you'll lose it for hours on the road, and you'll mostly use cellular for navigation, the occasional WhatsApp to a guide, and offline-translated menus. Plan on 0.5–0.7 GB/day:
| Trip length | Roamzy ($5.73/GB) | Tourist roaming pass | Local SIM at Ivato |
|---|---|---|---|
| 1 week | $22.94 (4 GB) | $45–110 | $10–25 + paperwork |
| 2 weeks (RN7 trip) | $45.88 (8 GB) | $80–180 | $15–35 + 30-day cap |
| 3 weeks (multi-region) | $68.81 (12 GB) | $150–300 (multiple passes) | $20–45 + 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 local SIM at Ivato is genuinely cheap on paper, and for a long stay it's a reasonable choice. The trade-off is the queue, the passport, and the language gap at the counter. For a one- or two-week trip the eSIM is faster and the math is comparable.
Coverage across the regions
| Region | 4G/3G | Reality |
|---|---|---|
| Antananarivo | 4G | Solid in the central neighborhoods and along the airport road |
| Antsirabe, Fianarantsoa | 4G | Workable in town centers; weakening on the highway approaches |
| RN7 corridor (Tana → Tuléar) | 3G/4G in patches | Long stretches without signal between towns; expect 30–60 min gaps |
| Nosy Be (resort island) | 4G | Reliable across Hellville and the western beaches |
| Diego Suarez and the north | 4G in town | Patchy on coastal roads |
| Andasibe / Ranomafana rainforest | 3G/4G | Near the lodges; on trails, none |
| Avenue of the Baobabs (Morondava) | 3G/4G in town | Weak at sunset spots; expect drops |
If you're driving the RN7 or flying internally to Nosy Be, download offline maps before you leave Tana. The eSIM picks up signal as you arrive in towns, and that's the realistic pattern — connectivity at stops, not always between them.
What you'll feel about Madagascar specifically
- The road is the trip. Driving the RN7 to Tuléar is two days minimum, often three. Cellular fades in and out across the high plateau. Plan for offline maps and a printed itinerary.
- French and Malagasy on signs. The translator camera is your friend at restaurants outside Tana. Pre-cache the language pack on Wi-Fi.
- Card payments work in Tana, Nosy Be, and the larger hotels. Outside that, expect cash in MGA. Your bank app for the occasional bigger payment needs a connection.
- Internal flights matter. Tana to Nosy Be saves a 24-hour drive. The eSIM stays attached and bills at the same rate the moment you land.
How do I install my Roamzy eSIM?

- 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 (on home Wi-Fi before flying)
- The counter starts the moment you land at TNR (Ivato)
Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
The most useful thing we can tell you about connectivity in Madagascar is where it won't be. The country is huge, the population is rural, and the network follows the people. Cities are fine, the RN7 has gaps, and the rainforest has nothing. That's geography, not a tariff problem — and no eSIM cures it.
- No welcome promo that flips on the second top-up. Top-up #1 and top-up #20 cost the same per megabyte.
- No fine-print throttling on day five of the road trip. One rate, full speed when you have signal.
- No auto-renewal you forgot to cancel after the trip. 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 route extends to other countries?
- Mauritius — most common Indian Ocean pairing, short flight east
- Seychelles — frequent regional connection
