Stay Connected in Bissau

Connectivity in Bissau works, but unevenly. Set expectations before you land. Mobile data is how most people get online, currently 4G in central Bissau and patchy 3G once you head toward the suburbs or out to the Bijagós ferry terminal. Fixed broadband exists in upmarket hotels but tends to wobble during evening peak hours. Here's the catch. Power cuts knock WiFi offline regularly, so even a paid hotel connection is no guarantee. The flip side is that mobile networks generally stay up through outages. That's why most residents and seasoned visitors to Bissau treat a local SIM or eSIM as the primary connection, and treat hotel WiFi as a bonus on top. As of now, prepaid mobile data is affordable by regional standards, registration is straightforward, and English-speaking staff at carrier shops are limited in number. Bring a few words of Portuguese or French.

Guinea-Bissau has two main mobile carriers worth knowing: MTN (the market leader, with the broadest 4G footprint in Bissau and along the main road to Gabú) and Orange, which arrived more recently and has been pushing aggressive data pricing to win share. A third, smaller player, Telecel, operates but with thinner coverage outside the capital. In practice, MTN tends to be the safer default if you're moving around the country, mainly toward Bafatá or the Bijagós islands, where Orange thins out. Inside Bissau itself, both networks deliver speeds that work well enough for video calls, maps, and social media. You might still get the occasional dropout in the Bandim and Belém neighborhoods during evening peak. Don't expect fiber-grade speeds anywhere. Fair warning. Upload speeds in particular tend to lag, which matters if you're sending photos or backing up to cloud storage. Coverage gets spotty once you're outside the main population centers. Plan offline maps first. Bring them for the islands.

Public WiFi in Bissau hotels, the airport lounge, and cafes around Praça Che Guevara is usable but worth treating with caution. Open networks are leaky. Anyone on the same access point can potentially see unencrypted traffic, and travelers make attractive targets because you're likely logging into banking, booking sites, and email from unfamiliar networks. The practical fix is a VPN, which encrypts everything between your device and a trusted server, so even on a sketchy hotel network your traffic looks like noise to anyone snooping. NordVPN is one well-regarded option that works reliably on Guinea-Bissau's mobile and WiFi networks. Past the VPN, basics still matter. Keep your phone's OS updated. Avoid logging into your bank from cafe WiFi when you can use mobile data instead, and turn off auto-connect to open networks so your phone isn't quietly joining whatever it sees.
