End Taxpayer Funded Cell Phones Act of 2017 This bill prohibits a provider of commercial mobile service or commercial mobile data service from receiving universal service support through the Lifeline program, which provides subsidies for discounts on monthly telephone or broadband service to qualifying low-income consumers. For 2018, telecommunications carriers must contribute to the universal service fund based on mobile service support provided in 2017. The amounts collected for mobile services must be used for deficit reduction.
