I have the SMS enabled across devices though. If the SIM is in my iPhone, my Mac, iPad, Watch, and iPod touch all receive the messages if the phone gets them. When I yank the SIM out of the phone, put it back into an Android phone, sure, the Mac, iPod, Watch and so on stop getting messages but again, all my family's texts still come to the Android phone as SMS, not being 'captured' by Apple.
I am not sure what everyone else is doing but I just pop the SIM into another phone and carry on.
