T-Mobile has agreed to pay a $15.75 million fine and improve its security in a settlement over a series of data breaches over three years that affected tens of millions of customers.

"T-Mobile suffered data breaches in 2021, 2022, and 2023," the Federal Communications Commission Enforcement Bureau said in an order approving a consent decree yesterday. "Combined, these breaches affected millions of current, former, or prospective T-Mobile customers and millions of end-user customers of T-Mobile wireless service resellers, which operate on T-Mobile's network infrastructure and are known as mobile virtual network operators (MVNOs)."
