Should I rely on Barcelona public Wi-Fi or use a CoreESIM data plan?

CoreESIM strongly recommends utilizing a dedicated data plan over public Wi-Fi in Barcelona for superior security and consistent performance. While 'Barcelona Wi-Fi' offers basic connectivity in some public spaces, it often operates on shared, unencrypted channels, posing potential privacy risks. Furthermore, bandwidth can be highly variable. A CoreESIM data plan ensures a private, high-speed connection via established carrier networks like Vodafone or Orange, essential for secure transactions, reliable navigation with apps like Google Maps, and uninterrupted communication across the city, from Gothic Quarter to Sagrada Familia.
