THE Cybercrime Investigation and Coordinating Center (CICC) has issued a warning against unknown calls claiming the receiver's SIM card was due for suspension for being used in unlawful activities.

CICC Executive Director Alexander Ramos said his office has received complaints concerning an anonymous caller who would introduce herself as an employee of the Department of Information and Communications Technology (DICT) and say that the receiver's SIM has been recommended for suspension for various violations. In one case, the caller used the name Nikki Garcia.
