MANILA, Philippines β Deactivated subscriber identity module (SIM) cards after the April 26 registration deadline may still be reactivated within five days after that date, the National Telecommunications Communication (NTC) said Friday. This gives a final chance for SIM card owners who failed to enroll their details within the registration period to keep their mobile numbers. Under the SIM Registration Act, unlisted SIM cards within the registration period will be automatically deactivated after the deadline, which is April 26. But NTC Deputy Commissioner Jon Paulo Salvahan noted that the lawβs implementing rules and regulations (IRR) provide the revival of the deactivated SIM card. Photo from NTC/SIM card. INQUIRER FILES
