Is a high-speed data connection from DataESIM critical for GPS navigation in Saint Lucia?

Utilizing applications like Google Maps or Waze with real-time updates is essential for safe and efficient transit, particularly when navigating the less-developed East Coast roads or complex routes around the Pitons.
