If i go on cricket's website and register a cricket phone, will I be able to check on my account activity, such incoming and out going calls. Is this feature available on a cricket online account?
No, One of the reasons that cricket is unlimited account info, is because they don't track your usage like other companies. You can order your caller ID log, but its limited on the amount of time you have
i believe the official policy on call logs is that they require a subpoena, and a $35 fee to get the list, although I have heard of people having success getting it from a direct store by payong the fee, no subpoena required.
