Hello Goremoreman,
Welcome to the community!
As far as I am aware, there is no text message (SMS/MMS) forwarding service from Fido (or any other provider). I do understand there may be some apps which are able to automtically forward messages. However, since those apps would be installed on the users' devices, the messages would need to be received on those devices before they can be forwarded. Apple devices do have the ability to forward messages to other devices (see here). However, I believe the phone would also need to recieve the text messages first.
Hope this helps 😀
Cheers
