Check Find My or Find My Device from another phone first: the last known location is stored even after the battery dies, and that is where the search starts. If it is not lying in plain sight there, a metal detectorist nearby can walk that ground, because a dead phone is still a battery, a frame and a board that a detector hears clearly. Here is what to do in the first hour, and how to get someone nearby to walk the ground.
From any other device, or a friend's. The last known location is stored even after the battery dies, and it is usually within a few dozen metres. Screenshot it before you do anything else.
People search where they remember being. The phone is where the map says it last was. Drop a pin there, and a second one where you last used it if that is different.
Put it in lost mode so it locks and shows a contact number on the screen. Do not erase it: an erased phone can no longer report where it is, and a searcher who finds it can't reach you.
If there is any battery left, the sound gives it away in grass or leaves. Turn the volume up remotely if you can, and walk the spot slowly, once.
A phone is a battery, a frame and a circuit board: a big target that a detector hears clearly. In long grass, under sand or in leaf litter it is invisible to eyes and obvious to a coil. Dead or alive makes no difference to the machine.
A back pocket, a sit down, a towel shaken out. The phone is in the sand, face down, exactly where that happened.
A pin on your phone, a photo of the spot, the story. Searchers nearby see only a rough area, never the pin.
A detectorist who already searches that ground offers. You pick them, and only they get the exact spot.
They hand it back in person. Any thank-you is between the two of you; nothing goes through us.
How soon the request goes up and how tightly you can draw the area decide most of it. Same day, with a spot somebody can stand on, is a very different job from a whole beach a fortnight later. Retrievly is free, and it handles no money at all. The full version.
You can post without an account; we just ask where to reach you at the end. Signing in is for searchers.
