You already support Apple Watches but not Family Setup (https://support.apple.com/en-us/HT211768) so that I can let my kids have a watch without them getting my phone calls and messages. Please add support for Family Setup like Verizon already has.
Second this! I'm switching to Visible for my phones and within about 6mo plan on getting Apple Watches for my young kids (Family Setup, withOUT phone service for them though). So, supporting this would be HUGE!
