How do I use an Onstar Mic for a bluetooth phone?

IPhoneMy bluetooth headset or any other mic when used on my phone works i can hear people but thy cant hear me?

• I can use the mic that came with the iphone that is just the standard ear phones that have the mic on them or i can use my bluetooth headset and both of them i can hear the person im talking to but they cant hear me no matter what headset i use. so i don't think it is the headset because i used my friends headset which we both know works and it still has the same problem so i know its not the headset its the phone... so what can i do to fix this?

• Answer:

  i would take it to your network which is probably at&t and have themm look at the problem.... or you could try to take it to a shop to get fixed.... but i would go with option one.... plus bluetooth sucks on all iphones
