Adding an Apple Watch to my account for a child
I have the Magenta Max plan with 3 lines with an iPhone on each (me, wife, son). I want to add an Apple Watch for my daughter as a standalone device so she can call us in an emergency and so we can see her location when going to/from school (she is too young for an iPhone). When I try to buy a watch from T-Mobile online, the site keeps asking me which existing line I would like to add the watch to. I can't find any way to buy a watch and add a standalone line for it. I was hoping to take advantage oftheApple Watch SE 2 deal (24 monthly credits when adding a line) but it seems to be for a Digits line only, paired with an existing number. Is there a specific process for this? Or do I need to go to a store? thanks!
