You must make sure that the headset is flashing red / blue, that tells you that it is in pairing mode and ready to match with your cell phone.

Try deleting the headset out of your phone and then re-pair it back up and see if that corrects the problem.

You want to remember that newer phones are like small computers, so
they may become corrupt over time and you may need to reset them every
so often. Simply turn your phone off and remove again the battery for
a few seconds, then replace the battery and turn it back
on again. Then carefully follow the pairing instructions in the attached link.
