If at this time you do not hear a tone out of the earpiece your phone needs to be replaced or repaired
If you do hear a tone, the there must be a setting that needs to be changed
If you do not know someone who can fix your phone, your service provider can normally replace it for you at a nominal fee assuming you have no "Physical or Liquid damage" ... Service plans are great, a lot of times you can get away with signing up, having the phone replaced then canceling a month later with no penalty. ASK BEFORE you try: Is there a service plan? How much Monthly? Is there a penalty at any time if I decide to stop participating with the service plan?
