Stay Connected in Guinea-Bissau

Connectivity in Guinea-Bissau is, plainly put, a work in progress. Bissau itself has decent 4G coverage. You can manage messaging, maps, and the occasional video call, though speeds drop off noticeably once you head toward the Bijagós Archipelago or rural inland areas. Power cuts happen often across Guinea-Bissau, and they take cell towers down with them, so even a strong signal can vanish for an hour or two. Here's what catches travelers off guard. Data is cheaper than you'd expect, but topping up often means tracking down a scratch card vendor rather than tapping an app. WiFi in Bissau hotels runs slow and shared, fine for email but painful for anything heavier. The honest truth: Guinea-Bissau rewards travelers who arrive with a backup plan, whether that's an eSIM ready to activate or a willingness to spend an afternoon sorting a local SIM properly. Plan ahead.

Two carriers dominate Guinea-Bissau: MTN Guinea-Bissau and Orange (which absorbed the former Areeba/Spacetel network). MTN has the broader rural footprint. That matters if you're heading toward Bafatá, Gabú, or the eastern regions. Orange is the stronger pick if you're staying in Bissau and want faster data, with 4G LTE available across most of the capital and in pockets of Canchungo and Bissorã. Speeds in central Bissau typically land somewhere in the 10-25 Mbps range on a good day, which works well enough for video calls, though you might get the occasional dropout. Once you reach the Bijagós Islands, expect to drop to 3G or sometimes 2G-only. On smaller islands like Orango or Bubaque, you may have signal in one corner of the village and nothing fifty meters away. Coverage gets spotty outside the main areas. Fair warning. Neither carrier sells 5G as of now, and roaming agreements with international carriers are limited, which is why most visitors end up with a local SIM or eSIM rather than relying on their home plan.

Hotel and café WiFi in Bissau is usually open or shared with a single password, which means anyone else on the network can potentially intercept unencrypted traffic. Travelers make attractive targets. They log into banking, email, and booking sites from unfamiliar networks, and most won't notice a compromise until weeks later. A VPN like NordVPN encrypts everything between your device and the wider internet, so even on a sketchy café network in Bissau, your passwords and messages stay unreadable to anyone snooping. It's worth setting up before you arrive, since downloading and configuring a VPN on slow hotel WiFi is its own small headache. Use it whenever you're on networks you don't control, above all for banking, work email, or anything tied to your identity. Mobile data on a local SIM or eSIM is meaningfully safer than public WiFi. When in doubt, switch to cellular.
