1. Is your current Maxis account a family plan? 1 primary account with multiple sublines? If so, you need to tell Celcom to port them all out simultaneously in 1 application. Not 1 number could be remained behind. e.g. if your account has 4 numbers and you are only porting out 3, it will fail. This needs to be in 1 application, as separate applications will cause it to fail too.

2. No such thing as need 1 month time after your contract before you can port out. If this really happened, you can contact MCMC at https://aduan.skmm.gov.my/ as this is against the law.

3. Your outstanding balance must be 0. If you are porting out at your billing date, wait a few days and pay your bill before attempting to port out.

There is a cooldown period for MNP, if you MNP from Maxis to Celcom, you need to wait for at least 1 month before MNPing to other Telco again. No such thing as need to wait 1 month after contract finishes before you can MNP out - I MNPed to Celcom on the day I cancelled my contract with Unifi Mobile.

For outstanding charges, you can call Maxis hotline to confirm you do not have any. You do not have to pay first any unbilled amount that you may have before MNP out. Good luck bro!
