Use the Soktaku self-position notification function

How to know the position when your smartphone is lost

If you are a Sokutaku user and there is no other person to notify you of your location,
If you register your own address, in the unlikely event that you lose your smartphone,
From other smartphones (smartphones with Soktaku installed)
You can check the location of your lost smartphone by logging in with the address.

However, Soktaku must be running on the lost smartphone.
(I think it’s a good idea to start it in the background)
