How can Apple's mobile phone check last year's call records?

If you need to inquire about the details of mobile phone calls, log in to the online business hall/click on the phone bill inquiry > details inquiry > call details to inquire about the details of calls in the last six months (including the current month). You can't query beyond the time limit, because local policies are different. Please refer to the local conditions for details.

Tips: The specific functions and paths of the online business hall are subject to the corresponding actual pages.
