For all Kogan Mobile prepaid plans and add-ons, internet usage deducted from your included data is rounded to the nearest KB.
Both downloads (data you receive) and uploads (data you send) count toward your data usage.
Unused data expires on next recharge or the expiry date, whichever is earlier.
If you use up your included data before its expiry date, access to data will cease until you recharge or purchase a data pack.
Information about your call and data usage can be viewed in the Kogan Mobile members area here.
