Comcast and Charter Communications appointed Michael Willner, the co-founder of Insight Communications Inc., as the chief executive officer of the new cable carrier they’re creating.

Willner was CEO of Insight, one of the 10 biggest US cable operators, until 2012 when he sold the company to Time Warner Cable, according to a statement. Since then, he has been CEO of closely held Penthera Partners, a software licensing venture focused on cloud-to-mobile technology. He also was the chairman of the National Cable and Telecommunications Association twice.

T-Mobile US introduced a mobile-phone plan that will prevent users from exceeding their data limits and incurring extra charges.

For $40 a month, a customer can get as much as 500 megabytes of fourth-generation LTE data service, along with unlimited talk and text messages, T-Mobile said on its website. The Simple Starter plan, which starts April 12 and doesn’t require an annual contract, won’t charge overage fees because customers won’t be able to use more than their data allotment. Instead, they will be prompted to pay more if they want additional access.

Chief Executive Officer John Legere said the plan is designed to be a “predictable, affordable solution” for new, price-sensitive customers. “People shopping at the $40 level want to pay that amount, not get surprised with overage charges,” said Mike Sievert, chief marketing officer of Bellevue, Washington-based T-Mobile. A customer who reaches the 500-megabyte limit and wants additional data allotments would pay $10 for an extra gigabyte, Sievert said.
