I have a 9, almost 10 year old daughter. Not really ready to buy a phone for her. I had an Apple Watch Series 3 with mobile and traded it into a Series 4 with mobile. I have not enabled the phone on the series 4. My question is that if I wanted to keep 3 for her, I could have both the bells paired with my phone and have mobile on her watch and use my only for texting and candy. I'm kind of kicking myself for not thinking about this before. She goes to an age where she has more activities and may need to get in touch with me but not ready to go into a mobile phone. Thanks!
