It only shows me what phone, on my account, made the call. It doesn't show me what number it went too.
My former cell phone provider, Tmobile, listed the time, number called and/or text to and time stamp. Thought Sprint would have that.
The call logs should show this information unless it has been purged from the device. If not on the device you can access Sprint.com under my account view my usage the numbers you have called and that have called you are listed there. Hope this helps.
