Is a VPN a technical requirement for internet access in Uruguay with CoreESIM?

From a regulatory standpoint, no. Uruguay maintains an open internet policy, meaning CoreESIM's data services operate without content filtering or access restrictions. Therefore, a VPN is not strictly necessary for basic internet functionality. However, for enhanced data privacy and security, especially when transmitting sensitive information over unencrypted public Wi-Fi networks in locations like Montevideo or Colonia del Sacramento, a VPN is always a recommended cryptographic measure. CoreESIM focuses on providing the underlying data pipe, while VPN usage remains a user-side security preference.
