The app is intended for use with Wear OS.
Send current location via SMS using the watch's default messaging app. Allows you to use the LTE network when the mobile is not nearby.
It can be used as SOS or location sharing.
So far, Google does not provide availability on the watch to use another application to send emails or any other messaging, but its messaging application is very effective. You can use it as shipping history.
The application has an automatic SMS location launcher tile.
*Check the SMS messaging plans with your operator, it may be subject to charges.
