IN October 2022, President Ferdinand Marcos Jr. signed into law Republic Act (RA) 11934, or the Subscriber Identity Module (SIM) Card Registration Act. This became the first law that President Marcos signed since becoming the country's chief executive.

The law was passed to address the proliferation of spam and scam messages that have been targeting subscribers. SIM-related fraudulent activities and smishing, short for SMS phishing, occur when scammers send text messages to mobile phone users, tricking them into sharing personal information, making money transfers or getting involved in malicious schemes.
