I was thinking of doing something like this for text with LoRa. But, having kids I don't have time to do that. This seems really great!
I read the previous discussion, oof:

Make note of the privacy policy[1]. Some users may not like the data they collect. > Information Collected from Children: As detailed in Section 3.C, we collect voice audio during calls, call log information, and utilize the Parent-provided contact list in relation to the Child's use of the Tin Can Device. We may also collect device identifiers and technical usage data related to the Service.
This text does not appear in the link. I do see:
>Call Logs: We collect information about calls made using Phones, including the phone numbers you call or receive calls from, the date/time of the calls, and the length of the calls. We also collect network quality metrics and other technical data related to call performance. Please note that we do not record calls.
The version of the privacy policy cited in the previous discussion cited that voice audio is collected for the purposes of forwarding it to the other phone.
That privacy policy doesn't sound out of the norm for any telco, which will be subjected to laws that require https://en.wikipedia.org/wiki/Lawful_interception
Have you seen some of the Meshtastic hardware with built-in keyboards? https://meshtastic.org/docs/hardware/devices/lilygo/tdeck/
My six year old is a big Meshtastic fan.
I don’t know when that previous comment is from but the text it quotes is not in the linked privacy policy
Also note that if you buy a Tin Can unit, there's a noncompete clause: You agree not to "build, benchmark, or develop a competing product or service." So don't buy this if you work for a telco, or a voice communications service of any kind.
