Hello. My name is***** can help you with your question.
You haven't given us much information to go on, but I can provide you some basic information until you do. If your cell phone has a removable battery, please remove the battery momentarily, but the battery back in and then start the phone back up. If it does not have removable battery, then hold down the power button for several seconds until the phone shuts off completely. Then press the button to start the phone back up and when it completely starts, see again if you can receive a call. Also, are you able to place a call? Are any other sounds working on the phone? Any detail you can provide will help me help you.
