The CRTC sent a request to wireless firms across the country this week asking for more information on their roaming agreements with other carriers. In a note sent by email on Feb. 12, John Macri, the commission’s director of telecommunications policy, said the request for information was intended to assist the CRTC’s ongoing review into whether there is “unjust discrimination” or “undue preference” in the way wireless firms deal with other carriers on roaming. The notice to carriers asked for information on traffic volumes received from Canadian carriers they provide roaming services to for the years 2007 to 2012, broken up between voice minutes, data in megabytes and the number of text messages. It noted carriers were already asked for information about the revenues they receive from other Canadian carriers for roaming in a request that went out Aug. 30 last year. The latest order also asks for revenue and traffic numbers received from U.S. carriers for roaming, also broken out by voice, data and texting, as well as the money paid and volumes associated with roaming services on U.S. networks during the years 2007 to 2012. The letter said the CRTC must receive responses by March 5. Thirty-six companies are listed as recipients of this request, including incumbents Telus Corp., Rogers Communications Inc. and BCE Inc. The federal government, in its budget released Tuesday, reiterated its intention to amend the Telecommunication Act to “cap wholesale domestic wireless roaming rates to prevent wireless providers from charging other companies more than they charge their own customers for mobile voice, data and text services.” Those rules, the budget document added, will remain in place until the CRTC concludes its consultation on wholesale wireless roaming rates and decides on its own policy framework.
