Abstract: This disclosure describes a Telecommunications Service Subscription Integration (TSSI) system that generates an integrated service subscription for a client device operating on a telecommunications network. The integrated service subscription may aggregate service features from multiple service subscriptions, and prioritize application of one service subscription within the integrated service subscription over another, or one service feature within the integrated service subscription over another. The TSSI system may also determine whether client eligibility for a service subscription is current or has lapsed. In doing so, the integrated service subscription may be adjusted to remove ineligible service subscriptions and re-prioritize remaining service features. The TSSI system may monitor usage of an integrated service subscription and recommend additional, or alternative, service subscriptions.
