Can the mobile phone accept the other party's information after setting the family number?

Hello: it is only a privilege to apply for a family number. As for the mutual inquiry between call records and SMS sending records, it has nothing to do with whether to apply for a family number.

If you want to check each other's records, you need to have their mobile phone password and get their mobile phone. Because no matter whether you check the records on the mobile Internet or in the business hall, you will receive a second verification code on the other party's mobile phone after entering the mobile phone password. You must enter the verification code again within 10 minutes, otherwise you cannot query. As for those who often send text messages outside to publicize that they can monitor conversations and check records, I don't know if they can really be found. Anyway, false scams have been exposed on TV and the Internet, so it is not recommended to believe them.
