Hello, My daughter lost her 5S two weeks ago, and there seems to be no hope of finding it. Find my iPhone cannot find it anymore. So, we're thinking of moving on, and giving her an old 4S or an older Nokia feature phone since we still need to be in contact. Since we will need a new SIM for the same number, I'm hesitant because the SIM in the lost iPhone will be deactivated. This means it cannot connect to AT&T anymore, right? So if by some miracle the iPhone is found and turned on, even if I turn on Lost Mode or Erase iPhone, the commands will never get to the iPhone, right? Hope someone can clarify. Thanks.
