Looks like Koodo won't get this one...link to Motorola site.
Moto G5 exclusive to Bell/Virgin/Videotron.
Moto G5+ so far in US market, not yet in Canada.
This doesn't mean you cannot use the Moto G5 with Koodo. If you wait long enough, Virgin Mobile will offer crazy incentives for the phone with $0 upfront on a silver plan, keep the service with Virgin for 90 days, then cancel (or cancel next day if you want to stick it to the sales rep), and buy out.
Unlock code on ebay for $2-5 for the phone. It's $250 retail, but can be promo'd out nicely coming back to school followed by the holiday rush.
