Yes, CoreESIM mobile data is significantly more reliable than hotel Wi-Fi during frequent power outages (known locally as "délestage") in Guinea. When the electrical grid fails, hotel and café Wi-Fi routers cease to function. However, mobile network towers are typically equipped with robust backup generators, allowing them to maintain operation. CoreESIM, by connecting to these resilient mobile networks, provides an essential and stable data connection for critical communications, navigation, and other online activities, even when local power is unavailable.
