We (his parents) are on apple devices so figured maybe an older SE model but if there's a good Android option that's fine too.
I figured for connectivity I would just stick with something pre-paid since he won't be using it often.
Thanks!
There are el-cheapo Nokia models, as an example.
If you are going the smartphone way, there are just a handful of "right" (small) sized phones, Unihertz and Cubot come to mind.
There are also a couple of companies that sell purpose-build wearables for this, but their privacy situation is sometimes murky.
It's probably worth buying the cheapest pre-paid android phone you can and doing some test runs. When my kids were that age, battery management was the biggest issue we ran into (that and trying to explain Spam calls).
As a bonus, it gets them into radio. “Why can’t I hear you down the block?” “Maybe there’s a thunderstorm on the way.” “Huh?”
