The new plan will apply from the 1st of the month following the date of the change procedure.
For example, if you do the change procedure in March, the new plan will be applied from April 1st, and the charges will apply from your May bill.
If you change your plan at the same time as upgrading your model/adding a device, the new plan will apply from the day of application.
You can check the status of your plan on My au (Web).
