Four Canadian cell operators have been making Wi-Fi noises for years: A while ago, they announced a major agreement to interconnect their networks. Only trouble was, they didn't really have any hotspot action going at that point. Now, between them, they have a whopping 500 locations nationwide, with 500 more planned in the indeterminate future.
Meanwhile, smaller and fleeter companies have been eating their lunch by partnering with other networks worldwide. FatPort, a company I have followed for years already, has 300 locations in Canada and at least 3,700 other roaming locations worldwide available at no additional fee to their subscribers. Most recently, they signed a deal with NetNearU.
