Early Termination Fee

The Formula To Calculate Early Termination Fee*

(50% of the average monthly bill based on the last 3 months’ bills) multiply by (number of unfulfilled contract months)

Example: Supposed your last 3 months bills is $90, $140 and $130. Your average monthly bill is $120. You have 3 months remaining in your contract, when you want to proceed with an early termination, the amount is: 50% x ($120) x 3 months = $180

* Early termination charges are not applicable to Freedom Plans.

Express Closure Fee

For Freedom Plans Only 

Customers who are on Freedom Plans may terminate these plans without early termination charges, by giving us 1 month’s written notice. For termination of the Freedom Plans with less than 1 month’s written notice, an Express Closure Fee of $32.10 (inclusive of GST) will apply.
