If I subscribe to Roam Like Home Monthly, does it cover all my roaming/IDD usages within the bill cycle?

Roam Like Home Monthly will be effective only after subscription. Any usage before the subscription will be charged at standard roaming and IDD rates. For example, if your bill cycle is from the 1st to 30th of the month and you subscribe to Roam Like Home Monthly on the 15th of the month at 14:00PM, any roaming and IDD usage between the 1st to 15th before 13:59PM will be charged as per standard rates. Any roaming and IDD usage from 15th at 14:00PM onwards will fall under Roam Like Home Monthly offers.
