Apple

You are better off getting a refurbished or a model that’s a little cheaper or older on Amazon. They do sell on there try that. On fb marketplace a lot of them could be stolen and not be able to get it setup and you’re out of cash and stuck with a bricked phone that you won’t be able to activate let alone use. Also they may sell you a fake one too. If you want an I phone but do t have the cash go to Amazon and look up iPhones there that are refurbished
