For a typical 7 to 10-day Philippines trip covering Manila, Cebu, and an island like Boracay or Bohol, 10 GB is enough for most travelers. A 2 to 3-week multi-island trip with daily Grab, Google Maps, WhatsApp, and casual photo uploads usually needs 25 GB or unlimited. Heavy users uploading island-hopping content from Palawan or working remotely from Cebu cafés should pick the unlimited 15-day or 30-day plan. Ferry rides, island hops, and constant ride-hailing consume more data than expected.
