Ouagadougou: Expect reliable 4G connectivity across most of the capital, especially in the central business district and the administrative Ouaga 2000 neighborhood. The signal is strong around major landmarks and transport hubs like the main bus stations. Indoor coverage can be weaker inside large concrete buildings or the more crowded, covered sections of major markets.

Bobo-Dioulasso: As the country's economic hub, Bobo-Dioulasso offers good 4G service in its city center, around the Grand Marché, and the historic Grande Mosquée. The network is generally stable for browsing and navigation. You might find a weaker signal inside older, thick-walled buildings in the old town (Kibidwe district) or on the city's peripheries.

Koudougou: This major city provides dependable 3G and 4G coverage in its core areas, particularly around the university campus and central commercial zones. While service is generally good for calls and basic data, high-speed 4G can be less consistent than in the two largest cities. Signal strength typically diminishes in outlying residential areas.

Banfora: The town center of Banfora is well-covered with a stable mobile signal suitable for daily use. However, this is a key local quirk: when you travel to nearby natural attractions like the Karfiguela Waterfalls or the Domes of Fabedougou, expect mobile service to become very intermittent or completely unavailable. Be sure to download maps before leaving town.

Major National Roads: Connectivity is strongest along the N1 highway connecting Ouagadougou and Bobo-Dioulasso, with reliable 4G in cities and 3G coverage for most of the route. On other key roads like the N2, N3, and N4, signal quality degrades significantly outside of towns, often dropping to 2G or disappearing completely in remote stretches.

Abidjan-Niger Railway: The Sitarail train service between Ouagadougou, Koudougou, and Bobo-Dioulasso has intermittent mobile coverage. You can expect a usable signal when passing through or stopping at towns along the route, but service is frequently lost for extended periods in the rural areas between stations.

Southwestern Escarpments: In the southwest region around Banfora, including the Chaîne de Banfora, the hilly terrain and sandstone cliffs can create signal shadows. While service is generally available, you may experience more frequent and unpredictable signal drops here compared to the flat central plateau.

Eastern and Sahel Regions: Travel in the vast Est and Sahel regions in the east and north of the country presents significant connectivity challenges. Outside of the main provincial towns, large areas have very limited or non-existent mobile network coverage, particularly near the borders with Niger, Mali, and Benin.

National Parks and Reserves: Expect little to no cellular service inside protected areas such as Arli National Park, W National Park, and the Nazinga Game Ranch. These remote conservation zones are largely off-grid, and visitors should not rely on a mobile signal for communication or navigation.
