The Financial Post reports in its Tuesday edition that there is no rule governing how wireless providers notify family users of impending data overage fees. The Post's Emily Jackson writes that the CRTC questioned the merits of introducing such a rule as part of wireless code review, which is being debated at a four-day public hearing. The CRTC is tweaking the three-year-old code for an era of skyrocketing data usage. One of the top issues is the explosion of shared plans since the code was introduced. Complaints arise when, for example, a teenager blows the data limit and accepts extra charges without the knowledge of the account holder, typically a parent. Some providers also charge up to $50 in data overage fees per device instead of per account, which consumer groups argue is against the spirit of the code. Chairman Jean-Pierre Blais, who questioned whether children should be allowed to consent to data overage fees and whether the account holder or the device holder should be notified when data limits are blown. Consumer groups are lobbying for a rule that gives account holders the sole power to authorize extra data usage unless they specifically grant that power to other device holders on their accounts.
