I want to check the billing amount after cancellation

I want to check the billing amount after cancellation (for those whose au ID was the same as their mobile phone number when they signed the contract)

Even after cancellation, you can check your billing amount by logging in to My au
Please see below for detailed steps

This page provides information about cases where au IDs have not been merged (one au ID has one au/UQ mobile contract line registered).
Regarding au ID when logging in after cancellation
If you switch from au to UQ mobile/povo, or from UQ mobile to au/povo: There will be no change to your au ID.

If you did MNP porting: If you have performed MNP porting after August 18th, 2021, there will be no change to your au ID. If you have performed MNP porting before August 17th, 2021, your au ID will change to "au ID" +" _ (half-width underscore)" + "date of cancellation (YYYYMMDD)".

If you cancel, transfer, or inherit the contract: Your au ID will change to "au ID_(underscore)" + "date of cancellation (YYYYMMDD)".

If you have any questions regarding the cancellation date, etc. please contact our customer center.
