It successfully kept its average phone price up and managed to increase its net new subscribers, but its dependence on sales beyond North America has become evident in the long term. The addition of total subscribers has virtually flattened in the continent, and service revenue has kept dropping as more of its sales depend on prepaid access outside of Canada and the US, especially in Europe.
