Yes, an active data connection via your CoreESIM is highly advisable for utilizing navigation applications like Waze or Google Maps while driving in Bulgaria. Waze, in particular, is popular for its community-driven, real-time traffic updates, hazard alerts (e.g., potholes, speed traps), and road conditions. This dynamic information requires continuous data exchange to provide the most accurate and up-to-date routing, especially on intercity highways and less-familiar roads.
