If I get an LTE watch and pair it to my iphone Xs but then take an old iphone 5 and swap in my sim card from the Xs, will I still have wireless service and all that on my watch?
So does my iphone have to be on for the handoff to work. What if I leave it at home and the battery dies, does my watch service stop?It won't screw up your watch but you want have service on it nor will it get any notifications. The cellular works as a handoff from the phone its paired to. If its not paired to an active phone the cellular won't work and neither will any of the notifications.
