REPUBLIC ACT NO. 10639 – SECTION 4 says, “In the event of an impending tropical storm, typhoon, tsunami, or other calamities, mobile phone service providers are mandated to send out alerts at regular intervals as required by the National Disaster Risk Reduction and Management Council (NDRRMC), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Philippine Institute of Volcanology and Seismology (PHTVOLCS) and other relevant agencies.”
“The alerts shall consist of up-to-date information from the relevant agencies, and shall be sent directly to the mobile phone subscribers located near and within the affected areas. The alerts shall include contact information of local government units and other agencies required to respond to the situation. The alerts may contain other relevant information such as, but not limited to, evacuation areas, relief sites and pick-up points.”
“The alerts shall be at no cost, whether direct or indirect, to the consumers; and shall be included as part of the service providers auxiliary service. The alerts may be in the form of SMS (text messages), MMS, or email, as needed and appropriate.”
“President Aquino signed into law Republic Act No. 10639, which mandates telecommunications service providers to send free mobile alerts in the event of natural and man-made disasters and calamities,” said the New Media Team under the Presidential Communications Operations Office.
