The Philippines just enacted Republic Act 11934 which prevents anonymity of any cell phone users. This includes “burner phones”. This effectively turns the Philippines into a police state as this new law could be used to target specific individuals or groups for political reasons. Here is the relevant section in the act:
The state shall promote responsibility in the use of Subscriber Identity Modules (SIM) and provide law enforcement agencies tools to resolve crimes which involve the utilization and a platform to deter the commission of wrongdoings.
Towards this end the state shall require the registration of SIM by all users.
