Major international ride-hailing apps like Uber and Bolt are generally not widely available or commonly used in the Republic of the Congo, including its main cities of Brazzaville and Pointe-Noire.
While your eSIM will provide reliable data connectivity by connecting to the strongest available major network (such as Airtel or MTN Congo), enabling you to use any app that requires internet, the primary challenge is the limited presence of these specific ride-hailing services. Travelers typically rely on traditional taxis for transport within cities. You may find some local taxi apps, but their reliability and coverage can vary. It's advisable to confirm transportation options upon arrival or through local recommendations.
