Is a CoreESIM essential for Rome, or is public Wi-Fi sufficient?

While Rome offers public Wi-Fi in some tourist areas and cafés, its performance is often inconsistent, slow, or requires cumbersome registration. For uninterrupted navigation with applications like Google Maps, secure online ticket bookings, or consistent communication while exploring iconic sites such as the Colosseum or Vatican City, a CoreESIM provides far superior reliability and security. It ensures dedicated mobile data without dependence on shared, unsecured networks.
