Do you mean who has called your phone, including text messages, etc? You could go to your carrier and ask for a by call statement to view online. This will show you all out going and incoming calls and text.

Depends on your service provider, some do not furnish any records beyond a bill. Others will provide a detailed bill, many online,

It will all depend on who your provider is and what type of service you have

I agree with the above poster. My providor proveds me with a list when I receive my statements each month! Depends on your providor and service?
