1 Back Up Your iPhone Regularly
Okay, this isn’t an anti-theft measure necessarily. But it is a good step in case your phone does get stolen. An iPhone, though pricey, is ultimately replaceable — but important pictures, messages and videos likely aren’t.
If you regularly back up your iPhone, losing it or having it stolen will be much less of a hassle. Better yet, you can remotely wipe the device using Find My iPhone to prevent thieves from accessing your data without the risk of permanently losing anything important.
