I got my teen kid an iPhone SE 2022 couple years back. It cost me nothing with 24 month bill credits. Carriers usually have an iPhone on us deal on 16E/SE.Which model iPhones would you recommend?
The best option would be to see if he can get one via the carrier - like the option mentioned above by @klasma.
But if we go down the path of buying off of say eBay, for the basic needs I mentioned above, which models would provide reason functionality and not be outdated?
iPhone 8?
iPhone 11?
iPhone 12?
Ideally looking for something under $250...
Try getting an iPhone 12, it will still support security updates longer than earlier iPhones. And budget another 80-90 bucks for replacing battery if it can’t hold charge.
