Key takeaways
Guinea-Bissau is one of West Africa's least-visited and most naturally spectacular destinations, with the UNESCO-listed Bijagos Archipelago as its centrepiece. Connectivity is improving but limited: Orange has the strongest coverage in Bissau and main towns, while the Bijagos islands have very limited signal. A Roamix Guinea-Bissau eSIM gives you the best available local network on arrival at Osvaldo Vieira Airport. Budget 2 to 4 GB and download everything before heading to the islands.
- Orange Guinea-Bissau has the best coverage in Bissau city and main towns; MTN provides secondary urban coverage.
- The Bijagos Archipelago has very limited mobile coverage; download all maps and guides before the boat crossing.
- Guinea-Bissau uses the West African CFA Franc, also used in Senegal and most of francophone West Africa.
- Portuguese is the official language; Creole (Kriol) is the everyday lingua franca across ethnic groups.
- A Roamix eSIM activates on arrival at Osvaldo Vieira Airport without a SIM kiosk visit.
Best way to get data in Guinea-Bissau
For visitors to Guinea-Bissau, a Roamix eSIM is the most practical option, connecting to Orange for the best available coverage in Bissau and the accessible parts of the mainland.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Connects to Orange Bissau on arrival, no SIM visit required and no surprise roaming bill. |
| Local Orange SIM | Best for: Extended stays needing a local number | Available at the airport and Orange stores in Bissau. Requires passport registration. |
| Hotel wifi | Best for: Stationary use in better Bissau hotels | Unreliable outside the capital; unavailable in the Bijagos. |
| Carrier roaming | Best for: Emergency fallback only | International roaming rates in Guinea-Bissau can be very expensive; a Roamix plan is far more economical. |
Better hotels in Bissau have wifi, though speeds are often slow. Guesthouses on Bubaque have very limited wifi. On most Bijagos islands, there is no wifi or mobile coverage.
How much data you need
Data needs in Guinea-Bissau are modest and focused on essential logistics. WhatsApp is the primary communication tool; navigation apps are critical for Bissau's unstructured road layout and the Bijagos boat connections.

How to set up a Guinea-Bissau eSIM
A Roamix Guinea-Bissau eSIM is best installed over wifi before departure. It activates on arrival at Osvaldo Vieira Airport, connecting to Orange Bissau.
- 1
Buy your plan on the Roamix Guinea-Bissau eSIM page before departure.
- 2
Scan the QR code or tap to install the eSIM over wifi.
- 3
Label it Roamix and keep your home SIM as primary for calls and texts.

Roamix sets the correct APN automatically on most devices. If data does not start on arrival, apply the APN from your order and toggle airplane mode.
No data on arrival usually means data roaming is off for the Roamix line. Check settings, select Orange Bissau manually and restart.

When you land in Guinea-Bissau
0 of 5 done
How people message here
WhatsApp is the dominant messaging platform and essential for all logistics in Guinea-Bissau. Kriol is the daily vernacular across all ethnic groups; Portuguese is used in formal settings.
Do you need a local number?
A local number is not strictly required for tourist visits. WhatsApp with your home number covers all practical communication with guides, hotels and boat operators.
Save your hotel, guide and emergency contacts in WhatsApp before landing; coverage can be very limited in the Bijagos and rural areas.
Airports in Guinea-Bissau
OXB
Osvaldo Vieira International Airport
Bissau
No reliable public wifi in the small terminal; mobile data is the only practical connection on arrival.
Activate your Roamix eSIM before landing to communicate with your pickup driver via WhatsApp and navigate into Bissau from the terminal.
BQE
Bubaque Airport
Bubaque, Bijagos Archipelago
Very small airstrip with no public wifi or facilities.
Domestic flights from Bissau to Bubaque bypass the lengthy Geba River boat crossing. With very limited island coverage, download your Bijagos accommodation details and island maps over Roamix data before departure.
Apps and internet access in Guinea-Bissau
Guinea-Bissau has a fully open internet, so all common apps work normally on a Roamix eSIM.
There is no systematic censorship of social media or messaging in Guinea-Bissau.
WhatsApp, works
The primary communication tool in Guinea-Bissau; widely used by guides, hotels and transport operators.
Google Maps, works
No restrictions; download offline maps for Bissau, Bijagos main islands and the eastern region.
Social media, works
Facebook and Instagram work normally on Orange 4G in Bissau.
FaceTime and video calls, works
Works over Orange 4G in Bissau; quality degrades on 3G outside the capital.
Getting around Guinea-Bissau
Guinea-Bissau has very limited public transport. Bissau itself can be navigated by shared taxis (candongas) or motorcycle taxis. Between towns, bush taxis run infrequently. For the Bijagos, the only options are pirogues (dug-out boats) and occasional motorboat services.
Bush taxis and shared transport
Bush taxis link Bissau to Bafata, Gabu, Canchungo and Cacheu. Departure times are unpredictable; use WhatsApp over Roamix data to coordinate with your guesthouse on the current schedule.
Boat to the Bijagos
Regular boat services run from Bissau port to Bubaque. Once in the archipelago, pirogues and motorboats connect the islands. Download all information before boarding as the islands are largely off-grid.
Private car hire
Private vehicles with a driver can be arranged through Bissau hotels for mainland trips. Use your Roamix eSIM to coordinate with your driver and navigate.
Bissau has no public bus system. Shared taxis (candongas) run fixed routes within the city. Negotiate prices before entering any private taxi. For intercity travel, arrange transport through your guesthouse.
Money and payments in Guinea-Bissau
Guinea-Bissau uses the West African CFA Franc (XOF), the same currency as Senegal, Mali, Cote d'Ivoire and other ECOWAS francophone countries. EUR can be exchanged at Bissau banks. CFA is essential for all transactions.
- Cards and cash
- Cards are not widely accepted outside a few Bissau hotels. Cash is required for all markets, transport, guesthouses and island services.
- ATMs
- ATMs exist in Bissau from Ecobank and BCEAO-affiliated banks but are unreliable. Withdraw sufficient cash before any travel outside Bissau as ATMs are nonexistent in the Bijagos and rural areas.
- Payment apps
- Mobile money services exist but are not accessible for tourists. Cash is the only reliable payment method outside Bissau hotels.
- Tipping
- Tipping is not culturally expected but is appreciated. Leave a small tip for guides and drivers; 5 to 10 percent is generous.
Daily budget
Budget travellers can manage on USD 30 to 60 per day; Bijagos island packages including boats and guides cost USD 80 to 200 per day.
Local tips for Guinea-Bissau
- Language
- Portuguese is the official language but only used formally. Kriol (Guinea-Bissau Creole) is the daily lingua franca spoken by virtually everyone. Some knowledge of French helps in border areas with Senegal and Guinea.
- Food
- Guinean-Bissauan cuisine features rice and jollof rice dishes, grilled fresh fish from the coast, caldo de mancarra (peanut stew), fried plantains and cashew fruit juice during the April to June cashew season.
- Plugs
- 220V, Type C plugs
Apps worth having
WhatsApp
communication
Essential for all logistics in Guinea-Bissau, from boat bookings to guide coordination and accommodation confirmation.
Google Maps
navigation
Download offline maps for Bissau city, Bubaque and main Bijagos islands; street navigation in Bissau without a map is very difficult.
XE Currency
finance
Track CFA Franc and USD exchange rates to ensure fair money exchange transactions.
Safety and health in Guinea-Bissau
Guinea-Bissau is relatively safe for tourists by regional standards but requires preparation. The country has a history of political instability; check your government's travel advisory. Petty crime exists in Bissau. Medical facilities are very basic.
- Stay reachable
- Keep your Roamix eSIM active to stay in contact with your guide and accommodation. In the Bijagos, inform your boat operator of your island schedule and planned return to Bubaque.
- Health
- Yellow fever vaccination is mandatory for entry. Malaria prophylaxis is essential. Cholera and typhoid vaccinations are recommended. Medical evacuation insurance is essential as local facilities are very limited.
- Tap water
- Tap water is not safe. Use bottled water for drinking and tooth brushing. On Bijagos islands, ensure your guesthouse provides safe drinking water.
Networks and coverage in Guinea-Bissau
Guinea-Bissau has two main mobile operators: Orange Bissau and MTN Guinea-Bissau (operating as Spacetel). Orange has the stronger coverage and provides limited 4G in Bissau, while MTN covers urban and semi-urban areas on 3G. A Roamix Guinea-Bissau eSIM connects you to Orange on arrival, providing the best available network without a SIM kiosk visit.
Orange Bissau
Strongest coverage in Bissau city and the main towns of Bafata, Gabu and Canchungo. Provides limited 4G in Bissau and 3G in major provincial centres.
MTN Guinea-Bissau (Spacetel)
3G coverage in urban areas of Bissau and main provincial towns. Weaker rural reach than Orange but competitive in city coverage.
- Typical speeds
- Orange 4G delivers 5 to 20 Mbps in central Bissau; 3G delivers 2 to 5 Mbps in provincial capitals.
- 5G
- No 5G network exists in Guinea-Bissau. Orange limited 4G is available in Bissau; nationwide travel relies on 3G and 2G.
Orange is the recommended carrier for data. In the Bijagos, expect to be largely off-grid; download island maps, boat schedules and accommodation details in Bissau before the crossing.
Outside Bissau and the main provincial towns, coverage drops to 2G voice only or disappears. The Bijagos Archipelago has very limited signal on most inhabited islands and no coverage on uninhabited islands. The eastern Gabu and Bafata regions have significant rural gaps. Orange Guinea-Bissau 4G operates on standard West African LTE bands. Recent unlocked GSM phones will work; check your device supports Band 3 (1800 MHz) for 4G.
Where to go in Guinea-Bissau
Guinea-Bissau is a tiny, rarely visited country with extraordinary natural riches. The Bijagos Archipelago is a UNESCO Biosphere Reserve of labyrinthine mangroves, green turtle nesting beaches and forest buffalo. The mainland blends Creole coastal towns, cashew forests and Fulani and Mandingo interior villages. A Roamix eSIM is essential for navigation and logistics in a country with minimal tourist infrastructure.
Best time to visit
November to May (dry season) is ideal. December to March is the best period with cool Harmattan conditions. Turtle hatching season at Orango and Joao Vieira islands peaks from October to February.

Through the year
- Spring
- March to May is warm and dry, with cashew harvest underway from April. The harvest season brings community activity to villages across the country.
- Summer
- June to September is the rainy season. Heavy rains from July to September make many bush roads impassable and complicate Bijagos boat crossings. The country is lush and very green.
- Fall
- October to November marks the end of the rains and the beginning of the cashew harvest preparation. Turtle nesting season begins at Joao Vieira. Good wildlife conditions.
- Winter
- December to February is the dry season and best travel time. Cool Harmattan breezes make the climate very pleasant. Turtle nesting peaks at the Bijagos islands.
Working remotely from Guinea-Bissau
Guinea-Bissau is not a practical remote work destination. Power cuts are frequent, internet is slow outside Bissau and co-working infrastructure does not exist.
- Connection
- Orange 4G in Bissau can handle email and WhatsApp. Video conferencing is unreliable. Use your Roamix eSIM as backup when hotel wifi fails.
If remote work is necessary from Bissau, choose a hotel with a generator and confirm wifi speeds. Use early morning hours when network congestion is lowest.
