I'm looking for a phone for my child that can only make and receive calls from the parents, without access to the internet or the ability to install or use other apps. Would a smartphone running a Linux-based or de-Googled Android system, such as LineageOS, be lockable enough to completely disable internet access? Or would a basic feature phone be safer and simpler? I've considered older Nokia-style phones, but I'm concerned that many no longer work on modern carrier networks. Any recommendations?

A smartphone seems like overkill if the only requirement is calling. You could use device-management tools, remove nonessential apps, block app installation, and disable mobile data and Wi-Fi, but it takes more setup and there may still be ways around the restrictions. A phone plan with no data could help, although Wi-Fi would still need to be blocked separately.
You might also consider a calling-enabled watch, but battery life and emergency features can be limiting. Feature phones made for seniors or minimalist users are generally a better fit, although they often cost about as much as an inexpensive smartphone.
A basic flip phone or feature phone is probably the simplest option. There are still current models designed for minimal use, but make sure the one you choose supports 4G LTE and your carrier’s voice technology. Older 2G, 3G, and CDMA-only phones may not work anymore, and some newer feature phones still include limited web browsers.
