Upgraded account payments and minutes are associated with individual member accounts, not the matched account. Each member's account status (paid or free) is independent of the co-parent's account status.
If one parent upgrades their account this does not automatically upgrade the co-parent's account. Also, the co-parent does not have to upgrade their account. A co-parent does not have to upgrade their account if the other co-parent chooses to upgrade. Both parents can communicate even if one parent is Free and the co-parent is Standard or Premium.
*Free members can receive Phone Calls. Standard members can receive Phone and Video Calls. Only members with a Premium Plan can start Phone and Video Calls.
