For the first one, sabi ng Globe Customer Service (about 5 years ago), naka link ang 112 sa local police hotline. Sabi ko walang sumasagot. Di na daw nila problema yun. (I felt my life was in danger at the time.)

For the second one, I doubt it. Di ba RF ang alarm remote?

The third one actually just turns on/off the EFR or enhanced full rate mode. If it is turned off, the phone uses less power.

Fourth, nasagot na nung iba.
