hello

I have a question??

About three months ago, my iPhone 7 Plus phone was stolen, so I immediately locked the phone through my iCloud and left a contact number.

Two weeks after the theft, I received this message on the mobile number that I had left when locking the phone.

I wanted to know if this text message was from Apple or from a phone thief

Please answer me carefully because I am looking for the phone from the security police.

Thanks
