I have an iPhone and an Apple Watch. For my elderly mother I want to buy a second Apple Watch, with LTE. This is in case she falls or something else happens and she has to call for help.
However she doesn't have an iPhone and I want to avoid buying an iPhone just for the Watch, since it won't get used at all. Can I associate the second Watch with my own iPhone, but make it use a different Apple ID which I create for my mother?
