Teleglobe's charges are substantially higher than for long-distance calls of equivalent length over the North American telecommunications grid, where competition and choice exist, or for overseas telecommunication calls that are routed via the United States, where competition and choice also exist.
It is cheaper to make a long distance call from North American than from at least one other place.
The article only talks about the expense of making calls from Teleglobe vs over the North American grid or via the United States which is part of North America. We don't know where or what Teleglobe is, or how much long distance costs in other places, so this is maybe true or maybe false. I think the system was confused by my wording.
