Purchasing a used iPhone is cost-effective and convenient. You can enjoy the superior iOS system while saving your cash. We highly recommend you to buy the used or refurbished iPhone from an authorized Apple reseller since many lost iPhones have been sold on some chaos second-hand markets. If you find that the iPhone you just bought is already linked to an Apple ID,  you are likely to purchase a lost iPhone.

If the iPhone is in Lost Mode, you can see the contact information of the previous owner. In this case, we recommend you to contact the previous owner and return the iPhone because there is no way to unlock the Lost Mode. If the iPhone is activated or has iCloud activation lock, you can refer to the unlocking ways from here. But we still recommend you to return the iPhone if possible.
