With Locale and the SMS Plug-in, your phone can send SMS messages automatically based on conditions like location and time.
Keep your family up-to-date. Control your home automation system. The possibilities are endless!
Note: Sent SMS messages will not appear in your Android SMS app, due to restrictions in Android that forbid this plug-in from accessing your sent messages.
This is a plug-in: it requires "Locale" from the Google Play store.
