It was a frustrating evening for Rogers Communications’ wireless customers across the country when part of the company’s network went dark.

The telecom giant restored its wireless voice and text messaging services late Wednesday night after a major outage.

The company’s data services did not appear to be affected by the outage.

Rogers’ spokeswoman Jennifer Kett said customers with wireless carrier Fido, Rogers’ lower-priced label, were also affected.

In a statement on the company’s website, Rogers president and CEO Nadir Mohamed says he recognizes the outage was ”unacceptable” for customers.

He said technicians worked as quickly as possible to restore service and sincerely apologizes for this ”significant inconvenience.”

Rogers has not yet determined what caused the problem, which produced a torrent of negative customer reaction on social media networks.

”We’re continuing to investigate the root cause of the issue to help ensure it doesn’t happen again,” said Mohamed.

”To thank our customers for their patience, Rogers and Fido will proactively credit all of its postpaid wireless customers for one day of service.”

Rogers has about 10 million wireless customers across Canada.

Rogers is the parent company of City, CityNews and CityNews.ca.
