SafeLink is run by a subsidiary of América Móvil, the world’s fourth largest wireless company in terms of subscribers, but it is not paid for directly by the company. Nor is it paid for with "tax payer money," as the e-mail claims. Rather, it is funded through the Universal Service Fund, which is administered by the Universal Service Administrative Company, an independent, not-for-profit corporation set up by the Federal Communications Commission. The USF is sustained by contributions from telecommunications companies such as "long distance companies, local telephone companies, wireless telephone companies, paging companies, and payphone providers." The companies often charge customers to fund their contributions in the form of a universal service fee you might see on your monthly phone bill.
