I don't think this is an indiviual number thing. It's a basic feature that Videotron de-activated.
Check this article: https://www.techwyse.com/blog/online-innovation/send-sms-through-email-to-usa-and-canada/
An organization I work with comuniticates with it's thousands of members using an Email to SMS gateway, however, doesn't work with videotron, therefor I don't get important messages I need. I currently have them sending to a friends BELL cell number, and then she forwards to me.... but it shouldn't have to be that way.
For example...this works
xxxxxxxxxx@txt.bell.ca
but there is no videotron option.
it's not a service that videotron has desactivated... it's a service that videotron chose not to offer.
