no brand Elegant Pink Smartwatch for kids

Smartwatch for kids. Can make and answer calls, and send text messages. It has a pedometer, calculator, and games. Was bought from Amazon but never used. Still has the screen protector. It has a SIM card inside, but I never activated it and don't know how. Maybe you just need to buy another one and put it inside. It's great for kids who don't have a phone yet but you need to have contact with your child. No charger, but it's USB-C, fitting most phones.
