Some parents in our social circle have been getting their kids smart watches. This allows talk to text and phone calls, but pretty much no internet. These devices are also good for parental controls like allow listing phone numbers (first thing our friends son did was make crank calls :)
I frequently recommend the apple watch with cellular to families... it has nice built in support to be set up for a child, the watch form factor is nice for lots of kids (harder to lose), and you are still getting a premium product (important for the families that I work with).
Yes, but I thought they still required pairing with a iPhone to set up. Once set-up is complete they can be used independently, but my impression is that it requires pairing to an iPhone, at least initially.
