"Africa in miniature" — and the connectivity that comes with it
Cameroon is 475,000 km² with coast, savannah, equatorial rainforest, the Adamawa plateau, and the volcanic Mount Cameroon at 4,040 metres — the country gets called "Africa in miniature" for a reason. Yaoundé is the political capital, Douala the economic one and the main international gateway. The trip pattern depends on what brought you: business in Douala, conservation work around Korup, a Mount Cameroon climb from Buea, or a slow loop through the north (Maroua, Waza). Connectivity reflects population density: solid in the cities, patchy on the road, near-zero in the deep parks.
Roamzy charges $5.94 per gigabyte in Cameroon. That's $0.0058 per megabyte, billed in real time on Cameroonian networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 192 countries is the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor uses 0.5–0.9 GB per day: maps in Douala or Yaoundé, ride-hail in the capital, the camera-translator on French and English signage (the country is officially bilingual, which helps), video calls home, the WhatsApp coordination with a guide for Mount Cameroon or Korup. Call it 0.7 GB/day:
| Trip length | Roamzy ($5.94/GB) | Tourist roaming pass | Local SIM at DLA/NSI |
|---|---|---|---|
| 3 days (2.1 GB) | $12.48 | $20–50 | $5–15 + ID and a local form |
| 1 week (4.9 GB) | $29.11 | $40–90 | $8–20 + paperwork |
| 2 weeks (9.8 GB) | $58.22 | $80–160 (often two passes) | $12–25 + 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 Douala or Yaoundé Nsimalen is sold but the form wants ID, a counter visit after a long flight, and the 30-day window starts on purchase regardless of whether you've left the city.
Where does Roamzy work in this country?
Networks cluster on the populated south and the road network linking the major cities; the deep northeast and Cameroon's parks are thinner:
- Douala, Yaoundé, Bafoussam — 4G/LTE at 95%+, 5G in central districts
- Buea (the Mount Cameroon launch town) — solid LTE in town, weaker on the climb above the rain belt
- Limbe, Kribi (the coast) — 4G in town, intermittent on the resort coastlines
- The road from Douala to Yaoundé — continuous LTE on the asphalt
- Bamenda and the northwest — 4G in town, gaps on the back roads, security situation worth checking before travel
- The far north (Maroua, Waza) — 4G in towns, weak in the savannah, expedition-grade planning required
- Korup and Dja reserves — silence in the deep park, signal at the entry villages
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 on the first top-up that flips on the second. No fine-print throttling. No auto-renewal you forgot to cancel after the 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 continues to other countries?
Cameroon sits at a Central African crossroads:
- Nigeria — northwest border, Lagos via the road or by air; separate country rate
- Chad — north, the eSIM hands over at the border crossing
- Central African Republic — east, security situation worth confirming before travel
