Is it safe buying a used iPhone X?

Hello ~ Second hand devices may work well for you but so many variables to consider. The first concern is this…

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

Also:

The All Too Common SAD Reality of Buying a Used iPad/iPhone

I would read through both of these thoroughly. I would encourage you to consider a refurbished iPhone from Apple …it’s a much safer option.

Maybe something to think about.......a used phone comes with no warranty. A refurbished phone from Apple comes with a new AppleCare warranty, which you can extend if you like.

Hello again ~ I think you should definitely take into consideration the information that * Bob Timmons* posted. It should also weigh heavily in your consideration of buying your iPhone. Good luck with whatever you chose.
