ACF is short for Airtime Carried Forward – and it’s something we think is pretty awesome. ACF is any unused commitment (or airtime you haven’t used from previous months) that you accumulate over time.
On Contract, Top Up and BYO, you can accumulate airtime from previous months up to a maximum of three 3 times your monthly airtime inclusions. Pretty cool, right?
When you wave goodbye to your contract, you don't immediately lose your airtime.
However, any airtime carried forward will be removed upon cancellation and all unused airtime you receive in the current month will be removed after 30 days from cancellation.
Any included SMSs and Data will be removed immediately from the effective date of cancellation.
