Abidjan: As the economic hub, Abidjan boasts strong and reliable 4G/LTE coverage from major networks across key districts like Le Plateau, Cocody, and Marcory. Connectivity in tourist zones and business centers is excellent. You may experience slightly weaker signals inside large shopping malls or older concrete buildings, but service is generally consistent throughout the metropolitan area.

Yamoussoukro: The political capital offers solid mobile connectivity, particularly around the Presidential Palace, major government buildings, and the famous Basilica of Our Lady of Peace. While the city center is well-covered, signal strength can be less consistent on the far outskirts or deep within the large conference centers.

Grand-Bassam: In this coastal UNESCO World Heritage site, you'll find good 4G coverage throughout the historic French Quarter and along the main beach hotel strip. The signal is generally strong for outdoor use, but can sometimes be weaker inside the thick-walled colonial-era buildings or further down the less developed parts of the coastline.

San-Pédro: This major port city provides dependable network coverage in the city center and around the bustling port area. The main town and nearby beaches are generally well-served. However, venturing further into the surrounding cocoa plantations or to more isolated coastal areas may result in a less stable connection.

Bouaké: In Ivory Coast's second-largest city, expect reliable 4G service in the central business district, around the university, and at major transport hubs. The connection is typically stable for day-to-day use, though you might notice reduced speeds in densely populated market areas during peak hours or on the city's periphery.

Autoroute du Nord (A3) and National Roads: Mobile coverage is generally reliable on the Autoroute du Nord (A3) connecting Abidjan, Yamoussoukro, and Bouaké. On other major national roads, like the coastal A100 or the A4 eastward, the signal remains consistent near towns but can become intermittent or drop to 2G in long rural stretches between them.

Sitarail (Abidjan-Ouagadougou Railway): Connectivity along the main railway line is inconsistent. You can expect a stable signal when passing through or stopping at major towns like Dimbokro and Bouaké, but the signal frequently drops out for extended periods in the agricultural and forest areas between stations.

Dix-Huit Montagnes Region: In the western highlands around the city of Man, mobile signal is significantly weaker than in the country's central and southern regions. While service is available within Man itself, expect frequent signal loss when traveling through the surrounding mountainous and forested terrain, particularly near the borders with Guinea and Liberia.

National Parks and Remote Savanna: Vast protected areas like Taï National Park in the southwest and Comoé National Park in the northeast have virtually no mobile network coverage. Similarly, traveling in the remote northern savanna regions, especially away from main roads and towns, will result in prolonged periods without a signal.
