You may be blacklisted because you did not pay all of your bills after terminating your Celcom/ Digi line. When you terminate, you must pay two types of bills:
1. Outstanding bill
Charges up to the point where you requested to terminate or port-out from Celcom/ Digi.
Must be settled:
Celcom: Before you initiate the port-out request.
Digi: During the port-out process, you will receive an SMS notification. To successfully port-out from Digi, you will need to make payment within 2 hours of receiving the SMS.
2. Final bill
Charges incurred between the outstanding bill and the date of termination.
Must be settled at the end of billing cycle upon receiving the final bill.
Please note that once blacklisted, you will be unable to sign up for any postpaid plan from CelcomDigi or other service providers in Malaysia until you have settled the final bill. To remove your name from the blacklist record, pay the outstanding bills via these available payment channels.
