Does CoreESIM recommend public Wi-Fi or a dedicated eSIM for connectivity in Lisbon?

Updated May 30, 2026

CoreESIM's technical assessment indicates that while public Wi-Fi is present in certain Lisbon establishments, its service level agreements often entail variable speeds, intermittent availability, and inherent security vulnerabilities. A CoreESIM profile provides a dedicated, encrypted mobile data connection, essential for secure transaction processing and consistent application functionality. This ensures uninterrupted navigation through the historic Alfama district or along the Tagus River, bypassing the inefficiencies of searching for and authenticating public hotspots.
