The bandwidth is applicable 24 hours a day and there is no specific time limitation as to when you can use it. You can use it at any time of the day or night and it will cost you the same.
We do, however, include additional FREE after-hours data (00:00 - 08:00) every day on 100GB or higher monthly Capped DSL packages and bundles. The 1GB DSL capped account is excluded from this offer.
If you have finished up your normal monthly data allocation you will no longer be able to use the free data for the rest of the month, until you top up your account.
