Americans have been enjoying number portability for a while now (though not without its fair share of hiccups), but some surprising names make the list of countries that haven't yet taken the plunge; Japan, for example, just flipped the switch for fickle customers this month. It appears that next up will be our neighbors to the North, with Fido noting on their website that all major Canadian carriers will be allowing number transfers in "all metropolitan areas" no later than March 14 of next year. Regional carriers will still be on the hook to allow outbound transfers by the same date, but are given a reprieve until next September to get the inbound side working. Any Canadian readers out there anxious to make the switch? Tell us all those heart-wrenching stories in comments!
