If you joined us part-way through the month, you may see a part-month charge for the date you joined us until the end of this billing period (plus the usual full month in advance).

If you look at this example:

1. You joined us on 27 Sept.
2. This billing period ends on 17 Oct.
3. Your full month in advance starts on 18 Oct – 17 Nov.

If you've been with us for a while and have changed plans, you may see a part-month charge for your new plan for the period covering the date you switched until the end of the billing period (plus the usual full month in advance).

You may also see a part-month credit relating to your old plan because you had paid the full month in advance on your last bill but only used it for part of the month.

If you look at this example:

1. You upgraded from Small Mobile plan to Medium Mobile plan on 27 Sept.
2. We credited $30 because you were only on this Small Mobile plan from 27 Sept - 17 Oct, but had paid the full month in advance on your last bill.
3. You started Medium Mobile plan on 27 Sept so you were charged from then until 17 Oct.
4. Your full month in advance for your new Medium Mobile plan is 18 Oct - 17 Nov.
