Why isn't my HTC One mic working?

[AC Question]

Htc one mic not working

The mic on my htc was working fine, as I imputed the SIM card any calls I make would not work and no one could hear me, after this the mic was not working at all. Without my SIM card phone is fully functional, please advice on how to fix this problem.

Thank you,

Welcome to Android Central! With the SIM card in, did you try making calls on speakerphone, or with a headset (wired or Bluetooth)?
