Bissau
- Arriving
- Osvaldo Vieira International (OXB) is close to the capital; transfers are by taxi. The airport has basic 3G from Orange and MTN. Bissau is the capital and effectively the only place with functional data in one of Africa's least-connected countries. Download everything offline before arriving.
- On the subway and rail
- Bissau moves by shared taxis (toca-tocas) and minibuses; there is no metro. Coverage holds across the central areas, though speeds are basic. The Bijagós Archipelago, the country's main draw, has minimal or no coverage on the islands.
- Free public WiFi
- Hotels, where available, provide the most reliable WiFi. OXB airport has basic WiFi. Connectivity is concentrated in central Bissau; plan for a largely disconnected trip.
- Coverage in the city
- Orange and MTN run basic 3G across central Bissau and the Bissau Velho old quarter. Coverage is minimal elsewhere. The Bijagós Islands have very basic service on the main islands (Bubaque) and none on the smaller ones; this is one of the least-connected destinations on the continent.
- If you prefer a local SIM
- Orange and MTN sell SIMs in Bissau. Almost no international eSIM providers cover Guinea-Bissau, so a local SIM or hotel WiFi is the only realistic option; download maps and guides offline before any island trip.
Grab an eSIM before you arrive in Guinea-Bissau to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.

- 1
Buy and install at home on WiFi.
Installation is not the same as activation. You can install the Guinea-Bissau eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.
- 2
Screenshot your current APN before you swap.
If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.
- 3
Decide on your dual-SIM strategy.
Keep your home line on for SMS-based bank logins, two-factor codes, and emergency calls. Set the travel eSIM as the data line only. Most modern phones can do both simultaneously.
- 4
Disable iMessage on the travel eSIM line.
Otherwise iMessage will try to re-activate against the new line on arrival and you will spend the first ten minutes troubleshooting it instead of finding the taxi rank.
- 5
Download offline maps for Guinea-Bissau.
Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.
- 6
Activate at the airport, not before.
Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.
