Yes, CoreESIM mobile data offers significantly superior reliability during Ghana's frequent power outages, locally known as "Dumsor." While hotel and cafe Wi-Fi systems are directly dependent on grid power and will cease operation instantly, mobile network towers often possess independent backup power systems, such as generators or battery banks. This enables continued data transmission even when local power is unavailable. A CoreESIM thus provides a critical, stable communication lifeline, ensuring uninterrupted internet access for navigation, urgent communication, and essential online services during power disruptions.
