T-Mobile owes a large part to its 2015 successes to competitors like AT&T, CEO John Legere said Wednesday.
"The biggest donator last year was AT&T. AT&T contributed to the benefit of the rest of us with 1.5 million [postpaid customer] losses on the [year]," Legere told CNBC's "Squawk on the Street." Postpaid phone plans are those where the consumers' monthly bill is dependent on their usage.
"Now, Sprint has been kind of a long-term contributor [to us] of postpaid phones [although] lately, they've had a small gain," he said. "All of them, dumb, dumber, and yellow, contribute heavily to the un-carrier revolution."
Legere made his remarks after the company reported fourth-quarter earnings per share of 34 cents, on revenue of $8.25 billion. Analysts polled by Reuters expected 15 cents EPS on revenue of $8.20 billion.
