A Faraday phone for Facebook

I found an old iPhone and I wiped it. I joined it to my guest wifi network. I logged into the App Store and downloaded Tiktok, Instagram, and Facebook.
I then logged out of App Store.
No iCloud
No notifications
No other apps that I typically use
I logged into Instagram
I can airdrop to the Faraday phone for when I want to post an image to Instagram

Is this as isolated as can be?
