Almost always, yes. Guinea-Bissau's internet infrastructure can be quite fragile, and hotel Wi-Fi is often susceptible to frequent power cuts, which can leave you disconnected. Mobile towers, however, are typically equipped with backup generators, allowing them to maintain service during these outages. An eSIMAdventures plan acts as your crucial lifeline, providing a stable connection for essential communication, navigation, and emergency contact, far surpassing the often intermittent hotel Wi-Fi in Bissau.
