It is possible for multiple LifePaks to be active at any given time. However, there are limitations to this, based on the type of Subscription Plan and type of LifePak. How you choose to operate within these limitations is completely up to you!
For those with Basic plan, only one Public LifePak may be active at a time.
With the Personal plan, two Private LifePaks can be active at a time.
Finally, for the Premium plan, unlimited Public LifePaks are allowed, but only five active Private/Semi-Private LifePaks are permitted at any given time.
