Guinea-Bissau is one of West Africa's most rarely visited countries. Small, Portuguese-speaking, politically complex, and home to one of the continent's most remarkable ecosystems. The Bijagos Archipelago, a UNESCO Biosphere Reserve with 88 islands, hippos living in saltwater, Nile crocodiles, and traditional Bijago culture barely touched by modernity. The mobile situation reflects the country's infrastructure challenges: MTN has functional 4G in Bissau city and on the main roads. Everything else requires offline planning. The Bijagos islands, which are the main reason adventure travelers come here, have essentially no mobile connectivity. Download everything before leaving Bissau.
Small Portuguese-speaking West African country. XOF currency (Euro-linked). MTN dominant. Very limited tourist infrastructure. Political instability should be checked.
eSIM for Guinea-Bissau: the fastest option
Travel eSIMs skip the physical SIM process entirely. Buy online, scan a QR code, and your phone connects to a local network. No passport check, no airport queue, no SIM ejector tool. Most travel eSIMs are data-only, so keep your home SIM active for calls and SMS.
eSIM avoids the city store trip on arrival day. Local MTN SIM is slightly cheaper and more reliable for extended stays.

Supermarket
Large supermarkets carry prepaid SIM starter packs in the electronics aisle. No-frills packaging, but prices are fair and no registration delay if no ID is required.

Osvaldo Vieira International Airport has no SIM counter. Your first connectivity opportunity is in Bissau city, about 10 km from the airport by taxi.

MTN Guinea-Bissau leads on overall coverage with a rating of 4/5 for reach and 3/5 for speed. In cities, all providers perform similarly. Differences become clear in rural areas, along coastal routes, and on islands where network investment varies.
Real-world connectivity
Bissau city center has MTN 4G at 5-20 Mbps. Adequate for messaging and maps. The main road east toward Gabu has coverage in towns. The road south to Catió has coverage to about halfway. Bafatá (second city) has reasonable MTN coverage. Beyond these main corridors, coverage drops to 3G or disappears. The ferry to Bubaque Island in the Bijagos has no signal mid-crossing. Bubaque main town has weak MTN signal. Orango and other outer islands have no signal. The entire Bijagos experience from the moment you board the ferry in Bissau must be treated as an offline journey. Bring Garmin GPS or download full offline maps (Maps.me or AllTrails) before departure.
Our verdict on SIM cards in Guinea-Bissau
Best for: Bijagos wildlife and birdwatching visitors (offline prep required), Adventurous West Africa travelers, Researchers and NGO workers, Hippopotamus spotting on Orango Island.
Much harder for connectivity than neighboring Senegal or Gambia. Comparable challenges to Central African countries. The Bijagos experience requires the same offline preparation as Antarctic or Amazon travel.
Activation & registration
Check your phone is unlocked
Your device must be carrier-unlocked to accept a Guinea-Bissau SIM. Check Settings or contact your home carrier before you leave.
Choose a plan before you buy
Decide on data volume and validity period. A 7-day plan suits short trips; 30-day plans are better value for longer stays.
Bring your passport
Registration is mandatory. The vendor scans your passport ID page and enters details into a government portal. Keep your passport accessible.
Insert and configure
Insert the nano-SIM using the ejector tool. Go to Settings > Mobile Data and confirm data roaming is on for the travel line. Run a speed test to confirm you are connected.
