The National Suicide Prevention Lifeline will be shifting to its new three-digit dialing code across the United States starting this Saturday, July 16.

The company, which is currently seeking the FCC's permission to merge with T-Mobile, claimed monthly credits for as many as 885,000 customers under the US government's Lifeline program. But Sprint was ineligible to claim the federal funds, the FCC said, because it failed to report that the customers were not actually using the subsidized service. "It's outrageous that a company would claim millions of taxpayer dollars for doing nothing," said FCC Chairman Ajit Pai. The investigation into Sprint comes at a delicate time for the company as it seeks to complete its merger with T-Mobile. "When companies abuse the Lifeline program, we should throw the book at them," Jessica Rosenworcel, a Democratic FCC Commissioner, tweeted.
