DALLAS (AP) — Cellphone company MetroPCS Communications Inc. said Tuesday that its fourth-quarter net income tumbled 65 percent, hurt by a drop in subscribers.

The Dallas-based low-cost carrier earned $32 million, or 9 cents per share, for the three months ended Dec. 31, down from $91 million, or 25 cents per share, in the same quarter last year. Excluding charges related to its pending combination with T-Mobile USA, MetroPCS said it posted an adjusted profit of 11 cents per share.
