Prepaid
Paying for mobile service in advance by loading credit, then spending that credit on a data or call promo — with no contract or credit check.
The step people miss is that loading credit and subscribing to a promo are separate actions. Adding ₱300 of load does not give you data; you then spend that credit on a specific promo. Skip the second step and the credit drains at expensive pay-as-you-go rates.
Prepaid dominates the Philippine mobile market, so the promo range is deep and competitive. It is also what almost every visitor will use.
