Numerous threads discuss whether and how long cellphone carriers can retrieve info,
which would “place” a victim, suspect or witness (or at least, the phone) in a given location at a given time,
or show their incoming or outgoing transmissions.
For sleuthers, if one of the carriers below provides the cell service in question and
if the info on the list below would be helpful,
then check this link:

Retention spreadsheet (apparently a scan of a fax of a copy, etc.) appears there
(first from a PDF, Dept of Justice).

Retention Periods of Major Cellular Service Providers shows retention schedules for these carriers:
Verizon,
T-Mobile,
AT&T/Cingular,
Sprint,
Nextel,
Virgin Mobile.
Retention for most of the following info are shown:
call detail records,
cell towers used by phone,
text message detail, text message content,
pictures,
IP session, IP destination,
bill copies; payment histories,
(store surveillance videos), etc.
Hope this helps.
