Boybi, may hotline ang NTC AFAIK. Pero the usual process is you go to the NTC. You need to have two valid IDs with you and you need to have the original box of the phone with the IMEI sticker intact. The NTC would record your IMEI number, put it in their report. However, the NTC does not immediately block the unit. They still go through an "investigation and processing" phase - your stolen unit would only be blocked 10-15 days after the report. Filing the request is simple and quick. No fees needed.
