While living in Japan, our kid used a cellphone with 3 buttons.
1. Call mom, 2. Call dad. 3. Call Auntie.
These kid's phones were very common, inexpensive and worked great.
There is an entire ecosystem of kid's watches which do exactly that. Pretty much just a miniature cellphone with restricted functions that goes on the wrist like some sort of a tracking collar.
