I apologize if this is the wrong place, but I am hoping someone here can help with ideas.

One of my step-daughters, (7 years old) has expressed concerns about being at her dad's. I would like to get her an old iPhone (like an 11 or 12 maybe?) that we can setup for her to be able to video call us at least if there's any issues there. If there's any way to setup wifi calling without a cell number to tie it to, that would be a huge bonus!

I prefer an iPhone only because I already have an Apple family thing setup, and I can share her location and such.

I don't really think she needs cell service, at least not yet, but I don't really know. So maybe an unlocked phone is better? I'm flying a little blind here to be honest.

Anyway, searching online I can find stuff around $200-$250, which we don't really have right now.

Does anyone know a way I can get her a decent phone that's not tied to an account, and not end up getting scammed or a stolen device?

Thank you to anyone who can help in advance!!
