How long can the phone records be kept?

In the mobile or Unicom system, the record for routine inquiry is the last 3 months (except this month), and the call information of this number, all information since the use of this number, can be kept all the time (but if the number is cancelled midway, only the owner information will be kept, and the call record will be completely deleted).

Ordinary users can view the call records. As long as they have the password, they can see all the phone records in the last three months through self-service, inside the operator and the police in the form of letters of introduction.

Matters needing attention
