A Supplemental Plan is an optional plan offering associated with a Master Plan that can be purchased in combination with its parent Master Plan. Supplemental Plans provide the ability to add a variety of additional services that are not offered in a Master Plan. Any number of Supplemental Plans can be associated to a Master Plan. And a customer can purchase any number of Master Plans and Supplemental Plans, even the same Plan offerings.
In the following example, a customer purchases the “Mobile Phone” Master Plan and two(2) of it’s related child Supplemental Plans, “Data Plan”, and “SMS Test Plan”. Once a Master Plan and any of its child Supplemental Plans are purchased, it is then considered to be a Master Plan Instance on the account. An account can have multiple Master Plan Instances.
