How can Apple's mobile phone check the phone records two months ago?

IPhone can't save the phone records of several months ago, but it can query the phone records of several months ago through the operator's client. Take China Mobile as an example:

Log in to the mobile client APP with the mobile phone and service password.

After logging in, click Query-Detailed List Query-Call Record Query.

Enter the second verification code received by the mobile phone to select the query time (generally only records within 6 months can be checked).

Call record refers to all kinds of information recorded on the operator's switch by calling, called, calling short messages, called short messages and roaming calls initiated by fixed telephone users and mobile telephone users.

Call records provide a basis for operators to charge fees, and also provide a basis for users to verify their calls. There are usually three ways to query the call records, that is, online business halls and mobile phone business halls in the last six months (including the current month), or offline business halls of major operators.

Before querying, you need to confirm that you have the ownership and right to use the searched number, otherwise you can't query.

When inquiring online in the business hall, the owner needs to bring the original ID card for inquiry.
