While some London cafes and transport hubs offer public Wi-Fi, its reliability and security can vary greatly. For consistent, secure, and fast internet access while exploring landmarks like the Tower of London or navigating the Tube, an eSIM is far superior. It ensures you're always connected without hunting for hotspots or compromising data security.
