Well most of the telecom service providers have online web-sites which give you billing details, but it is highly unlikely that they will give online caller identification. You can apply for an itemized bill which will provide proper break ups on who had called up your cell phone, along with the date and time.
Caller ID basically is a telephony intelligent network service which broadcasts the caller's telephone number and in certain places the caller's name to the called person's telephone equipment during the ringing signal or when the call is being set up prior to being answered.
In America, CNID is normally broadcasted applying Bell 202 modulation between the first and the second rings, quiet a few systems also apply the "line reversal" method to announce the caller ID.
