(Telecompaper) The Federal Communications Commission has announced a settlement with T-Mobile US over the "inadequate disclosures" of its data plans, which were throttled at times of high congestion even though they were sold as unlimited. The FCC said the operator has agreed to pay a total of USD 48 million after its investigation found that "company policy allows it to slow down data speeds when T-Mobile or MetroPCS customers on so-called 'unlimited' plans exceed a monthly data threshold." The FCC added that: "Company advertisements and other disclosures may have led unlimited data plan customers to expect that they were buying better and faster service than what they received."
