There are, but it comes with the baggage of contracting an additional phone line, and more importantly having it charged at all times and on the kid.

Even just the risk of breaking, losing or getting it stolen is not negligeable.

It’s a viable option depending on the kid and the environment , I just feel kids phone are still too clunky to be worth it. I’d prefer to go straight for a regular smartphone once the kid is big enough to properly take care of it.
