The Globe and Mail reports in its Friday edition that most revenue growth in the wireless industry comes from the increasing use of mobile data. The Globe's Christine Dobby writes that during the second quarter, the three national wireless carriers, Rogers, Telus and BCE, together added almost 200,000 new contract wireless customers. The companies are all working to sign up subscribers to more lucrative smart phone plans that include larger monthly buckets of data. BCE chief financial officer Glen LeBlanc explained on an earnings call earlier this month that wireless service revenue in the period "increased 4.6 per cent, driven by higher LTE [4G] data usage," a trend noted by all of the carriers. The companies do not disclose exact figures, but their customer bases are shifting away from prepaid talk-and-text plans to more lucrative contracts, which are usually required to receive subsidies on the most popular smart phones. Ms. Dobby notes that average revenue per user (ARPU) is not an exact proxy for price, but it relates to the prices customers pay. All three carriers reported an increase in wireless ARPU in the second quarter, with Rogers at $60.18, BCE at $64.32 and Telus at $64.38 a month.
