Can I use a different AppleID on my Apple Watch? 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?
Apple has a setup guide for precisely this: Set up an Apple Watch for a family member
Since watchOS 7, you can set up Apple Watch for a family member using a new/separate Apple ID joined to the same Family Sharing group as your primary Apple ID. Choose ‘Set Up for a Family Member’ when prompted in the Watch app to begin the setup process.
