To register, you need to visit the official DITO Registration Portal or use the DITO APP on your phone. You'll need to provide your personal details, take a photo of a valid Government ID (like a Passport, Driver’s License, or National ID), and upload a selfie for verification. This is required by the Philippine SIM Card Registration Act to keep your number active and prevent it from being deactivated. Once you submit the form and receive a confirmation message, your SIM is fully registered and ready for use with their high-speed 5G/4G data services.
