Public Wi-Fi availability in Medellín, particularly in high-traffic zones like El Poblado or Laureles, can be inconsistent in speed and security. For reliable, secure, and always-on connectivity, a CoreESIM data plan is highly recommended. It ensures seamless navigation, ride-sharing app usage, and stable video calls without exposing your data on potentially compromised public networks. CoreESIM prioritizes consistent data access over opportunistic Wi-Fi reliance.
