The Financial Post reports in its Monday edition that Verizon and AT&T made their legacy unlimited data plans less desirable last week. The Post's Emily Jackson writes that Verizon is forcing its heaviest users to switch to limited plans or face disconnection, while AT&T raised its price for the grandfathered plans by $5 (U.S.) for the second time in a year. Their reasoning hints at why Canada's top three carriers have refused to offer unlimited data plans despite consumer demand. T-Mobile throttles speed after a data threshold, so some critics say it is not truly unlimited. In Canada, consumer advocacy group OpenMedia has pushed the idea of eliminating data caps. OpenMedia's David Christopher is confident his organization made a good case for mandating at least an optional unlimited plan so Canada can catch up with the United States and Europe where unlimited plans are "perfectly normal" despite the recent moves to pull back the benefit. "The telecom companies certainly have been dragging their heels when it comes to unlimited data," Mr. Christopher said. Rogers and Telus argue eliminating data caps would cause the rates to go up for most users, meaning light users would subsidize heavy users.
