There is a text message on my Apple phone saying that Huawei's equipment is locked. What happened?

Hello, dear, I'm glad to answer your question. Hello, dear. 1. Generally speaking, the reason why Apple's mobile phone is locked is that someone else locked your mobile phone on other Apple devices or web pages through the "Find My iPhone" function in iCloud. The premise of being locked is that the account password of your mobile phone login is also known by others, so you can lock the phone. You need to prove this yourself. Who knows your account number and password? 2. There is also a case of hacking. After the person who locks the mobile phone obtains the email address information, if the email address is registered with an Apple ID, the password of the Apple ID can be changed by resetting the password by email. Usually in this process, the password of the mailbox will also be reset. Subsequently, the other party can use the reset Apple ID to open "Find My iPhone", turn on the lost mode, lock the phone, and knock money to the owner. Before the phone is locked, the menu of locking and canceling will pop up on the phone page. If you click lock, you will be caught. You should change your password immediately after clicking Cancel. If my answer is helpful to you, you can give me a compliment after the consultation. Wish you all the best.
