Will Unicom receive a reminder of arrears before the mobile phone is in arrears? Can the call and SMS records during the arrears be displayed after the payment is resumed? Please be as detailed as possible. Thank you! The mobile phone will receive SMS reminders before the arrears or arrears stop.

There will be no call record during the arrears period, and users who make arrears calls will only prompt that the phone has stopped;

Because SMS can be stored in the message center for 72 hours, if the downtime of arrears does not exceed 3 days, SMS will be sent from the message center to the mobile phone after the mobile phone resumes service.
