If you are wondering how to check call record of other mobile number or to get call record of any mobile number let me guide you that only law enforcing agencies have the access to it and if any one gets or tries to get call detail record of any mobile number it is considered to be a crime as it is against the privacy of someone. However call history of any mobile number can be obtained by the orders of the court or competent authority and they can also permit to check sim call record of any number. Any access through private channel is a crime an FIR can be lodged against you.
