A prepaid plan has a minimum term in the same way a bank account has a minimum term: a period the money is committed for, not a period you are contractually bound to. Reading the two the same way is how customers end up surprised in both directions.
What the prepaid table states
The Boost prepaid pricing table separates two term groups: a 7 Day Expiry column and five 28 Day Expiry columns. Those are the expiry terms of the credit you buy. There is no contract tying you to a minimum number of recharges, and the cancellation field reads not applicable.
What the monthly plans state
The TPG Mobile SIM only service is supplied on a rolling month to month basis, so its minimum term is one month, renewable. The early termination charge field on every plan reads not applicable. The Optus prepaid data plan states there are no cancellation fees associated with this plan.
The distinction that decides your exit
- A prepaid recharge commits your money to a term; it does not commit you to the provider.
- You stop paying and the service ends; you do not owe a penalty for stopping.
- What you lose by stopping is the unused balance, not a fee.
- What you lose by stopping late is the number itself, because keeping a prepaid number requires keeping the service recharged or transferring it.
So the real minimum-term question for prepaid is not a contractual one, it is a practical one: how long will you be somewhere for this service to be worth keeping alive? That is the number to compare against the term, and it is the only one that varies per customer.
