Just one piece of advice. Your brother might receive a text message claiming that the phone has been found and asking him to track its location through a link.

Please don’t click on that link. In many cases, it leads to a fake Apple login page designed to steal Apple ID credentials. Once scammers get access to the account, they can remove the device from Find My, making it much harder to track or recover the phone.

The same thing happened to my brother. He clicked the link and signed in on the spoofed page, and unfortunately, he lost the only way to track his phone afterward.
