As long as your number is in our coverage area, you can transfer your number in to us. It’ll take about 3-4 weeks for us to get a number working for you once you’ve submitted your transfer request.
Also note, Canadian numbers are not considered as an included number in any plan, so they’ll cost $5 per month each. (If your plan includes 3 numbers, a Canadian number will still cost $5 per month.) Per minute costs are no different from US calls.
