Yes, CoreESIM mobile data offers superior dependability compared to local Wi-Fi, especially given the prevalence of scheduled or unscheduled power cuts in Sri Lanka. While Wi-Fi routers and local internet infrastructure are often directly affected by power disruptions, mobile network towers typically feature robust backup power systems (generators, battery banks). This ensures that your CoreESIM connection remains active, providing crucial access for navigation with Google Maps, emergency communications, or accessing online banking services, even when local power grids fail.
