There are a few different ways you can try to locate a dead AGM A7:
Check the last known location: If you have a smartphone, there are several ways you can track its location. One way is to use the "Find My Phone" feature on Android or "Find My" on iPhone. This will show you the last known location of your phone on a map.
Ask people you know: If you think you left your phone at a friend's house or at work, try contacting people you know and ask if they've seen your phone.
Check common places: Look in all the usual places where you might leave your AGM A7 such as your car, your purse or backpack, or your kitchen counter.
Contact your phone carrier: If you're unable to locate your phone, you may be able to get help from your phone carrier. They may be able to track the location of your phone or block it from being used by someone else.
If you're still unable to locate your AGM A7, it's possible that it's lost or stolen. In this case, you may want to consider contacting the police to report it as lost or stolen.
