Ask about local public transport
Filipinos are quite pleasant and courteous, especially in regions that aren't inundated with tourists. Almost everyone you meet will refer to you as "ma'am" or "sir." "Ma'am sir" is another option. They will appreciate your respect if you use the terminology when addressing them. Also, make an effort to meet and mingle with the locals; you will not be disappointed!
While app-booked automobiles in Metro Manila are very efficient, smaller provinces usually have their own public transportation infrastructure. Locals in some places can move around on a tricycle, jeepney, or multicab (all modified English phrases referring to Filipino public transportation vehicles) for very cheap. To prevent being overcharged, ask around when you arrive at a new location for the best means of transportation in the region and know the approximate cost of a trip.
