Will I have coverage in the Puerto Princesa Underground River in Palawan, Philippines?

While you'll have reliable signal in the main city of Puerto Princesa and around the visitor center for the Underground River in Palawan, expect the connection to be limited or absent once you enter the cave system itself. The dense rock formations naturally block cellular signals. However, EastESIM ensures you're well-connected before and after your boat tour, allowing you to share anticipation or post your incredible photos of the cave's entrance and surrounding nature. Signal will return once you emerge from this stunning natural wonder.
