@Paolo is correct You can use the 514 number to reach us from abroad! That said, since you're back in the fall we can always suspend your account (if you're off agreement) so that you can have the same number and plan once you're back in Canada!
Customer care can do that for you, if you prefer we can also send you a PM on the Community and we can help out!
Let us know
