In compliance with the SIM Registration Act in the Philippines, all mobile users, including TNT (Talk 'N Text) subscribers, must register their SIM cards to continue enjoying mobile services like calls, texts, and data. This mandate, effective since December 2022, aims to enhance national security, curb text scams, and prevent fraudulent activities.
