"Our ability to move quickly to take costs out of the business in response to changing market conditions helped offset declines from our MTS wholesale wireless revenues, and legacy revenues at Allstream," chief executive Pierre Blouin said in a statement.
The company said its MTS business earned operating revenue of $243.5 million, down slightly from $243.7 million a year ago, while its Allstream business saw operating revenue drop to $171.7 million from $200.2 million.
Included in the MTS operations was $91.5 million, up from $89.8 million in the first quarter of last year as total wireless subscribers grew to 493,216 from 488,571 a year ago. Average revenue per user was $60.25, up from $59.78.
Local access revenue, the company's traditional telephone business at MTS, fell to $64 million from $66.9 million a year ago, while long distance and legacy data revenue fell to $18.1 million from $19.1 million.
