He overpriced the phone. Good2Go have a 1GB data plan for $5/mo that I use. I only need data when I'm outside the house. You can buy a half-decent Android phone off eBay for $30-50. But, you still need some sort of Internet. If you can't get wired, then that means having to fork out for Starlink or Hughes.
I'm in literally the middle of nowhere in a one-horse town and it has 1Gbps wired to my house and they just put in a second company with 5Gbps the other day, which is wild.
