After the ID loan locks the mobile phone, only the original ID password can be unlocked. At this time, you need to bring your mobile phone warranty card, invoice, etc. Unlock after sale to prevent it from being locked. ID lock is a function set by Apple system to protect Apple users. After turning on my iPhone, if I refresh or upgrade, I will need to reactivate the Apple ID, otherwise I will be locked. The risk of ID loan being locked is still high. I suggest you apply for a loan from a regular lending institution, not such a risky loan.
