Also known as: carry-over
Carrying unused allowance from one billing period into the next. Rare on Usenet subscriptions, where monthly quotas normally reset to zero and unused gigabytes are lost. The behavior is standard on prepaid blocks instead, since block data has no monthly cycle to reset against and sits there until it is spent. Plans advertising rollover usually cap how many months accumulate.
