How many months can I check the phone records at most? Mobile discount for 6 months, can you learn more?

You can check the phone records of the last six months at most.

All major operators only keep records for nearly six months, so they can't inquire more.

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.

Online business hall inquiry: log in to the online business hall of the operator to which the number belongs, enter the number and service password to log in, and select "Call Record Inquiry". The website will send SMS verification code to the checked number, which can be used to query call records and provide downloading, printing and so on.

Check in the mobile phone business hall, enter the number and service password, and select "Call Details" to check the phone bill. After the inquiry, the system will send a short message to inform the customer that the call list inquiry function has been used.

Offline business hall inquiry: the owner needs to carry his personal ID card, show the owner's identity to the business hall staff, verify the inquiry password, inquire and print the call record, or enter the password in the self-service server for inquiry.
