How does Budapest public Wi-Fi compare to CoreESIM reliability?

While some cafes and public areas in Budapest offer free Wi-Fi, its reliability, speed, and security are often inconsistent and can be compromised. For a consistently reliable and secure internet connection, a CoreESIM is far superior. It provides dedicated mobile data access via established Hungarian networks like Telekom HU or Vodafone Hungary. This ensures uninterrupted connectivity for critical tasks such as navigating the city, using ride-sharing services, or securely accessing banking applications, particularly when exploring areas like Margaret Island or the Fisherman's Bastion.
