Republic of the Congo eSIM: connectivity priced by usage, not packages

Two cities, a railway, and a rainforest behind them

The Republic of the Congo — usually called Congo-Brazzaville to distinguish it from its larger eastern neighbour — covers about 342,000 km² and holds roughly 6 million people, the bulk of them along the rail and road corridor between Brazzaville (the inland capital, on the Congo River across from Kinshasa) and Pointe-Noire (the Atlantic oil and shipping city). Most foreign visitors are oil-and-gas business travelers in those two cities, NGO staff, regional diplomatic staff, or the rare adventure traveler heading north into the Odzala-Kokoua and Nouabalé-Ndoki forests for lowland gorillas. The cellular network covers the corridor workably and thins out in the rainforest interior.

Roamzy charges $3.69 per gigabyte in Congo-Brazzaville. That's $0.0036 per megabyte, billed in real time on Congolese networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 193 countries.

How much will Roamzy actually cost on this trip?

A typical visitor uses 0.4–0.6 GB per day on cellular, with hotel and lodge Wi-Fi handling the heavier work: maps in Brazzaville, the WhatsApp to a driver or guide, the camera-translator on a French menu, voice notes home. Call it 0.5 GB/day:

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 Congolese SIM at Maya-Maya (BZV) or Pointe-Noire (PNR) is workable for a long stay. For a typical 1–2 week visit, the eSIM is the simpler answer.

Where does Roamzy work in this country?

• Brazzaville — 4G across the working capital; signal along the Congo River corniche, on the road in from Maya-Maya, and on the ferry terminal area opposite Kinshasa
• Pointe-Noire — strong LTE in the Atlantic oil city and along the coast road south toward the border
• The Brazzaville–Pointe-Noire corridor (CFCO railway and road) — LTE through Dolisie and the populated towns; gaps in long forested stretches
• Odzala-Kokoua, Nouabalé-Ndoki — 3G at lodges; nothing in the rainforest interior where the gorillas actually are
• Northern districts (Ouesso) — 4G in the regional town, sparse on the river-and-road access
• Border zones — last few kilometres before Gabon, the DRC, or Cabinda often pull toward neighbouring networks

How do I install my Roamzy eSIM?

1. Sign in to Roamzy via Telegram or Google
2. Your first eSIM is free and comes with real data on us. After that, top up from $20 in stablecoins (USDT or USDC): no cards, no banks, no FX surcharges
3. The QR code appears in your dashboard as soon as the eSIM is issued
4. On the iPhone itself (iOS 17.4 or newer), tap Tap to install in the QR card; otherwise Settings → Cellular → Add eSIM → scan QR
5. The counter starts when you land at Brazzaville Maya-Maya (BZV) or Pointe-Noire (PNR)

Supported stablecoins and common setup errors are in the FAQ. The dashboard handles top-ups in USDT.

What are Roamzy's honest limitations?

• 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. One rate, full speed — first GB and the tenth both cost $0.0036/MB.
• No auto-renewal. Balance runs out, the eSIM stops.

In Congo-Brazzaville you're billed for the megabytes you use, and then the billing stops being interesting. That's not a slogan; it's how the tariff was engineered, with nothing hidden and therefore nothing to undercut.

What if my route continues across Central Africa?

• Gabon — north along the Atlantic coast, separate country rate
• DR Congo — across the river from Brazzaville, common rotation
