Is public Wi-Fi reliable in Berlin, or should I use an eSIM?

While some cafes, hotels, and public transport hubs in Berlin offer Wi-Fi, its reliability and security can be inconsistent. For dependable, secure, and fast internet access while navigating the U-Bahn, exploring Museum Island, or using ride-sharing apps, an eSIM is far superior. It ensures you're always connected without searching for hotspots or compromising data security.
