The most common mistake on a Guinea trip
Spending the first morning at a SIM counter in Conakry. The flight from Brussels or Paris lands at Gbessia, you're tired, the queue at the local SIM kiosk is forty minutes, the registration wants a passport scan and a residential address you don't have, and the resulting bundle is sized for residents on monthly contracts. Don't do that. Attach the eSIM at home before you fly, the counter starts when your phone catches the first tower in Conakry, and the WhatsApp to your driver runs before you've left the terminal.
Roamzy charges $5.73 per gigabyte in Guinea. That's $0.0056 per megabyte, billed in real time on Guinean networks. No subscription, no expiry on the unused balance, no minimum bundle. One per-MB rate across 192 countries — the figure on the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor uses 0.4–0.7 GB per day on cellular, with hotel Wi-Fi handling downloads and the bigger video calls: maps in Conakry, the WhatsApp to a fixer, the camera-translator on a French menu, voice notes home, the bank-app push for the contactless payment when it works. Call it 0.6 GB/day:
| Trip length | Roamzy ($5.73/GB) | Tourist roaming pass | Local SIM at Conakry |
|---|---|---|---|
| 3 days (~2 GB) | $11.47 | $25–60 | $5–15 + KYC and a passport scan |
| 1 week (~4 GB) | $22.94 | $50–110 | $8–20 + paperwork |
| 2 weeks (~8 GB) | $45.88 | $100–220 (often two passes) | $15–35 + 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.
A local Guinean SIM is workable for a multi-month posting. For a one- or two-week visit, the eSIM is the simpler answer.
Where does Roamzy work in this country?
- Conakry (Kaloum, Dixinn, Ratoma) — 4G across the working coastal city; signal on the road in from Gbessia
- Kindia, Mamou, Labé, Kankan — workable LTE in the regional centers
- Fouta Djallon highlands (around Pita and Dalaba) — solid 4G in the towns, weaker on the mountain trails to the waterfalls
- Forest region (N'Zérékoré, Kissidougou) — 4G in towns, sparse in the rainforest interior
- Boké and the bauxite mining corridor — strong LTE on the industrial routes, weaker further inland
- Coastal islands (Loos archipelago) — signal at the populated points, weaker on the boat
Driving the N1 from Conakry inland holds signal across most of its length; the smaller roads through the highlands and the forest region drop intermittently.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |

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 $0.0056/MB.
- No auto-renewal. 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 continues across West Africa?
- Sierra Leone — south along the coast, separate country rate
- Liberia — further south, the eSIM hands over at the border
